CHAPTER 1: INTRODUCTION 1.1

Title of the Project DAILY EXPENSE TRACKER

1.2

Topic Background The system itself defines its task, “Daily Expense Tracker” means it is a tracking system

which will save our daily expenses, credits i.e. from whom we have to get money, debit i.e. to whom we have to give and how much. Not only this but almost every work which involves transaction of money will be stored in this system and based on the data stored this expert system will give some predictions and reports. There are so many people who used to maintain dairy for their daily expenses so that they can use it for future. There are some people who used to remember their expenses but there counting is very less as in today’s scenario where there is no time for an individual to eat properly, sleep properly walk with their belongings for a moment then think for a moment how can they maintain their dairy which will again put a burden on their mind to remember those activities which they have done. Those people who want to save their daily expenses in such a place which will be handy to use. One of the most appropriate places to store the data is the mobile phone. Also in the dairy system, if the dairy is lost then it will be a heart locking situation.

1.3

Purpose of Implementation Developing a financial plan is important to your success. Regardless of your income,

financial planning WORKS. (Morgan(Admin)) We are in such an era today, that our most of the work has been shifted to computer; we are surrounded by the computer system which has harmed our memory. We feel hard to jot down every expense we do every day, due to lack of time and we used to forget the expenses made during the day. We used to forget whom we have to give money and how much as well as from whom we have to get. For this scenario this system is very much helpful to the user as you can write down the name and money at the same time. There is no need to memorize everything basically cost related tasks and expenses made during the course as this system provides you with all these facilities.

PT0981128


Daily Expense Tracker 1.4

Target Audience Anyone, ranging from home users to office user and any businessmen or professionals

interested in tracking their daily expense. People who want to schedule their budget. A person who wants to find his saving at the end of the day, month and year, as well as for him who wants to see his progress based on today’s saving. The system can be used by them who are careless in handling the device e.g. who usually finds their device stolen, broken etc. they can recover their data from the server. On the other hand, the system could be used to guide the user for being more expensive by providing notifications. All types of users aging more than 13-14yrs. This system will be used by administrator as well who will be manage the website and create a back-up plan if required.

1.5

Problem Context As almost all users are connected with each other with mobile, the trend to save small

pieces of data into mobile in logs, notes, reminders has increased. So users need a system which will make automatic calculation based on their expenses. It’s not so that there does not exist any system for the same but there are some problems which are listed below. There is lack of research and functionalities in the current system as well. We are in such an era today that our most of the work has been shifted to computer; we are surrounded by the computer system which has made our memory powerless. We feel hard to jot down every expense we do every day due to lack of time and we used to forget the expenses made during the day. We used to forget whom we have to give money and how much as well as from whom we have to get. For this scenario this system is very much helpful to the user as you can write down the name and money at the same time. There is no need to memorize everything basically cost related tasks and expenses made during the course as this system provides you with all these facilities. If you lost your device then the data can be easily downloaded from the website and hence you can be saved from a disaster.

1.5.1 Problem Area 1.5.1.1 Unable to know savings[PB1] 1.5.1.2 Unable to put limit on expense according to budget[PB2] 1.5.1.3 No offline-online data synchronization[PB3] 1.5.1.4 Slow data retrieval while searching[PB4] 1.5.1.5 Lack of security [PB5] PT0981128

1.5.1.8 Report generation [PB8] 1.5.1.9 No Prediction[PB9] 1.5.1.10 Only one session per mobile[PB10] 1.5.1.11 Cannot know the position from where the expense has been done[PB11]


Daily Expense Tracker 1.5.1.6 No backup and recovery for the data[PB6] 1.5.1.7 Manually scheduling[PB7]

1.5.1.12 No option to contact the developer in case any problem happens[PB12] 1.5.1.13 Manually sending of email or SMS to report someone about our expense [PB13]

Note: These problems are described in details in problem background.

1.6 Rationale This application provides benefits in many ways, like it allows users to save their daily expenses in a customized manner. It allows users to save their task in the system along with the position from where they saved the data. It allows users to save their wastage of money by providing notifications whenever required. It allows the users to know their future benefits by doing calculations based on their savings. The system to be implemented could bring about significant tangible and intangible benefits. Given below is a list of tangible and intangible benefits expected from the system:

1.6.1 Tangible Benefits 1.6.1.1

One time investment: Users will have to invest their money for just once to use this system on android mobile but to use the web services they will have to pay according to the plan.

1.6.1.2

Saving on Internet Data usage: there is no need to start the internet all the time when you want to save the expense details as this can be done offline. User can synchronize their data during their off time i.e. just once in a day or a week internet is needed. Hence wastage of data usage can be saved.

1.6.1.3

Accessibility of system: System can be accessible anywhere if the user has got the mobile. If mobile is not with him/her then the system can be accessible with the help of website if the user has a login id and password.

1.6.1.4

Reduces the stress: this system will directly reduce the stress from the user as the user will not have to calculate each and every thing ex. How much they have balance in their hand? Etc.

1.6.1.5

Data can be recovered: As the system database is online i.e. on remote server so if the user lost his/her device then they can get the desired data from the server again.

1.6.2 Intangible Benefits

PT0981128


Daily Expense Tracker 1.6.2.1 Economic Benefits: with the help of this system we can save our lot of money which goes in waste land due to the lack of planning. 1.6.2.2 Save time: this system will save our time as we can do hours of work in a minute. E.g. if we need to search a person whom we have to give money from our notebook then it will take hours if there are thousands of record but with the help of this system it will take less than a minute.

1.7

Project Objectives The objective of this system is to design such a system for users which will resolve the

problems related with daily expenses and save a lot of money by providing them necessary notifications and by showing their profit or loss based on daily expenses.

1.8

Functionalities of DET (Daily Expense Tracker) Functionalities of this system are divided into three categories namely Core, Enhanced

and Special functionalities. These are given below.

1.8.1 Core Functionalities of the System Core feature of any project is the heart of that project or you can say the features without which system is incomplete.

Feasibility study is further sub-divided into four categories as described below. 1.14.1 Schedule Feasibility Report It shows that whether the project development is going as per the schedule or not. This system is being developed as per the time given in the Gantt chart. All the major and minor activities are shown in the Gantt chart with completion date for all major activities within the project that meets organizational deadlines and constraints for affecting change. The main part of schedule feasibility report is-Gantt Chart- Developer has used this chart for the time estimation. (Refer to appendix)

1.14.2 Technical Feasibility Report PT0981128


Daily Expense Tracker Technical Feasibility mainly involves the hardware and the software requirements of the system regarding all the tasks of the system to be done. All the major technologies used to develop this system are described in section 4.2.1. From the report of section 4.2.1 we can easily know that this system is technically feasible. 1.14.3 Operational Feasibility Report: It may be defined as, the process of assessing the degree to which a proposed system solves business problems or takes advantage of business opportunities. Problems addressed and advantages of this system are provided in the documentation. 1.14.4 Economic Feasibility Report: The purpose for assessing economic feasibility is mainly to identify the financial benefits and costs associated with the development project. Economic feasibility is referred as cost and benefit analysis for any system. Once the technical feasibility is established, it is important to consider the monetary factors also. Since it might happen that developing a particular system may be technically possible but it may require huge investments and benefits may be less. Cost Benefits are included under Rationale (Section1.6) by the developer.

1.15 Ethics Commitment It ensures that the project won’t do any harm to the society or anyone in anyways. It contains issues like no animal harm & no copying of data without prior permission etc. and to ensure that the developer has filled up an ethical form and it will be provided in documentation. It also ensures no information of user will be leaked outside the system.

Critical Appraisal As per the problem context and functionalities given above the system is going to be developed in a systematic manner. This system will be very much helpful to the users and users will be going to enjoy this system very much. This system is feasible in every aspect whether it is technical or operational. User will be able to save his/her expenses into four categories i.

Income- amount which the user says it his/her income from various sources.

ii.

Expense- amount which the user will spend

iii.

Credit- amount which the user has given someone else and he/she will get in future.

iv.

Debit- amount which the user needs to pay other person in future.

CHAPTER 2: PROBLEM DESCRIPTION 2.1 Introduction to Problem Area Today there is a drastic change in livelihood of each and every people of this world. Either he/she belongs to a small family or middle family or why not from a large family. All are addicted to technology directly or indirectly. They do not have time to note down their income and expenditures on a piece of paper, in PCs, in mobile notes etc. and count them one by one to know their total budget. The developer do not say that there is no such systems which handles all these problems. Yes there are various systems to handle those problems but they are either time consuming or hard to work on. For e.g. we can save our data on excel sheet also but who have got the time to open the PC and remember all the expenses which we have done on that day. It’s really time consuming and boring. There is lack of research and functionalities in the current system as well. We are in such an era today that our most of the work has been shifted to computer; we are surrounded by the computer system which has made our memory powerless. We feel hard to jot down every expense we do every day due to lack of time and we used to forget the expenses made during the day. We used to forget whom we have to give money and how much as well as from whom we have to get. God shake it doesn’t happen with anyone but what if the hard disk crashes, files which we have saved are destroyed in natural disasters, or due to some other problem we lost our data then we are completely going to be mad. These are just the glimpse of the problems which is going to be solved with this system.

2.2 Problem Description and solution Following are the problems which are present in the current system. 2.2.1. Unable to know savings[PB1]

User is not able to know his/her savings without calculations. We have to do it either manually or with the help of calculator. Solution: this problem is solved by using the functionality CF2 i.e. save daily expenses in the system. Alternative solutions: user can save his/her daily expenses in excel sheet, notebook, PCs etc. 2.2.2. Unable to put limit on expense according to budget[PB2]

We are unable to put limit on our daily expenses on a particular thing and hence we do over expenses on a particular item. Solution: this problem can be solved by using the functionality CF4 i.e. by putting limit on a particular item. PT0981128


Daily Expense Tracker Alternative solutions: we can achieve this goal by making a different section for noting down the tasks on which we have to be cautious while over spending. 2.2.3. No offline-online data synchronization[PB3]

Current system only provides the either of the offline or online data saving feature. If the internet is not working then online system will not work and hence the user has to suffer a lot. Solution: this problem can be solved by using the functionality EF2 i.e. by synchronizing data between mobile apps to the web server. Alternative solutions: we can send our data on the mail ids, or server if we have manually. We can store the data in file of a particular user whenever system is communicating with the server. 2.2.4. Slow data retrieval while searching[PB4]

Data retrieval is slow in case of online systems depending upon the speed of internet connection. Hence user will have to wait for a long time for even searching a name of the item. Solution: using functionality CF7 i.e. by searching our daily expenses in the system we can easily achieve this target. Alternative solutions: by using CF6 i.e. viewing the reports of the system we can get the desired output. 2.2.5. Lack of security [PB5]

When the system supports only offline task then if the data is deleted or the mobile gets stolen all the data will be lost and user has to suffer again. Solution: by using functionality CF1 we can achieve this target i.e. by registering our self to the server and by getting a user id and password. Alternative solutions: by using functionality CF7 i.e. account management we can secure our account by being misuse. 2.2.6. No backup and recovery for the data[PB6]

There is no backup and recovery facility in the current system. That means once the device is lost or file is corrupted then there is no way to recover it. Solution: by using functionality CF8 we can easily make backup of our data and recover it whenever required. Alternative solutions: we can make duplicate copies of files and store it at different locations for backup in traditional file system. We can use file system which will get the desired data from the server and store it in the mobile till the internet connection does not comes. We

PT0981128


Daily Expense Tracker can use that data further as offline data. If our mobile gets lost then we can use the internet connection and download the app and get the data back again. 2.2.7. Manually scheduling[PB7]

In traditional file systems there was no option of scheduling along with tracking budget and provide notification when necessary. Solution: using functionality EF3 i.e. task manager we can schedule using our mobile. Alternative solution: we can make set alarm or remainder for the same purpose. 2.2.8. Report generation [PB8]

The report generation format is not up to the level. Only data which has been saved are shown. No customized report is possible. Solution: by using functionality CF6 we can generate reports in as per the requirement. Alternative solutions: reports can be generated in graphical format as well as textual format. 2.2.9. No Prediction[PB9]

The current system does not provide us any facility to view the future benefits. No prediction is there. Solution: by using enhanced functionality EF1 i.e. future prediction we can foresee our future benefits. Alternative solutions: we can predict manually by multiplying our savings in a month with 12 and so on. 2.2.10. No option to add items in customized manner and customize notifications [PB10]

There is no option to add our own customized items as per our requirement. Solution: we can add items in a customized manner using functionality SF1 e.g. if user is from outside India they can put their own currency symbol for their favor. Alternative solutions: we can assume that this and that symbol is for this purpose. 2.2.11. Only one session per mobile[PB11] There is only one user account in the current system. If there exists multiple users to work on the same mobile then there are no criteria for that. Solution: this problem is solved as user can “sign in” in the system using functionality CF1 and save their expenses. Hence multiple users can work with this system on a single mobile. Alternative solution: users can purchase dedicated mobiles for themselves so that no conflicts can occur. 2.2.12. Cannot know the position from where the expense has been done[PB12]

PT0981128


Daily Expense Tracker In earlier system we cannot know our position from where we saved the particular piece of information. Solution: while we are saving our data, system will automatically save the location using GPS technology which is given in functionality EF4 and hence we can find our exact location in future in case we require that detail. Alternative solutions: we have to write down the location from where we have saved the data manually. 2.2.13. No option to contact the developer in case any problem happens[PB13] We are not able to contact the developer in case of problem. Solution: using functionality CF10 we can contact the developer in need. Alternative solution: we can contact to another developer in local to solve our problem. 2.2.14. Manually sending of email or SMS to report someone about our expense [PB14]

When we have to send our expense report as email or SMS to our guardians we have to send it manually but with the help of this system auto sending of mail and SMS will be done. Solution: auto generation of mail and SMS will take place in the system using functionality SF3. Alternative solution: we can send the mail using Gmail manually. 2.2.15. No normalization process is followed: There is also a concern that the traditional file management system results in a lack of consistency when it comes to storing data, though this very much depends on the user and the nature of the data they are filing. (NA, Disadvantages of File Processing System, 2010) Solution: normalization process will be followed to develop this system whenever required. Alternative solution: We can remove duplicity of data whenever possible.

2.3 Challenges and Learning Opportunities The primary challenge in building this system is customizing the various user requirements based on their category e.g. students, businessmen, home users etc. the data which has to be customized should be gathered from various users. Some off the other challenges are given below

2.3.1 Challenges

PT0981128


Daily Expense Tracker Further challenges involved in this system are described below. 2.3.1.1 Saving data on external database other than SQLLite from android device: data which is in the device should be synchronized with the server so that the user can access it from anywhere. Challenging part here is that if the user saves any data in mobile when there is no internet connection and after sometime user saves another data from web browser then it’s very hard to make data consistency in the system. 2.3.1.2 Offline and online facility: providing both of the facility to the user so that user will feel free to work with this system. It was one of the most challenging part of this system as it covers 2.3.1.1 challenge also. The problem was to execute the query placed in JSP page i.e. web application with the help of android device. Initially the developer was working with the localhost with port no. 8080 but he found error as server not found. Then after a lot of research work he found instead of writing localhost in android we have to write 10.0.0.2. This is the path to the localhost from emulator. This was just a single problem, more problems are described in implementation part.

2.3.1.3 Graphical data: Showing graphical data to the user so that user can understand his/her expenses easily. It was really a hard nut to crack for the developer as there is no tool in android to draw graphical reports. So developer did a lot of research on this part and after trying many API’s developer had decided to work with Google graph. 2.3.1.4 System portability: making the system to be portable on various android devices. This issue made the developer a lot to worry as many functions which are available in the android newer versions are not compatible with older version of android say API level 8 does not have isEmpty() function to check the string whether it is empty or not. So developer had to make his own function to do the same. 2.3.1.5 When the screen orientation is changed the data provided to the system is lost which has not been saved in android application hence managing this screen orientation to be compatible with the system is one of the challenge in developing this system. 2.3.1.6 Managing reports and sending them on mail: various types of reports will be made and sent to the user’s mail so that user can get a clear and more detailed view of the reports. 2.3.1.7 Apart from these one of the challenges is making the GUI follow HCI principles. 2.3.1.8 Future saving prediction: on the basis of saving of the week/month predicting the future savings is one of the challenges to implement. 2.3.1.9 Knowing the user: To understand the spending habits of people. The manner in which they spend the money, decisions they take before spending on something. Other challenge would be of how to make this application make effective to make people use

PT0981128


Daily Expense Tracker the application, as some people would consider the application as ineffective in respect to the amount of time they give in use of the application. 2.3.1.10

Interaction design and coding is also one of the major challenges of this system.

2.3.2 Learning Opportunities Following are the learning objectives while developing this system. 2.3.2.1 Learning and practices of XML and Android Technology As this system is going to be developed entirely on android technology so learning of android technology is obvious. And XML is one of the core features of android to create the layouts then its knowledge is also most required. 2.3.2.2 Learning of synchronization of data between offline-online One of the toughest features of this system is to synchronize the data between mobile and server. So to achieve this target I need to learn the algorithm for the same. 2.3.2.3 Learning Web services To implement the web-services developer has to learn the web services also. With the help of web-services this system will be able to synchronize the data between server and mobile. 2.3.2.4 Learning to integrate android with web to develop a single system. After learning the web-services and android basic I will be able to implement the both to create a single integrated system. 2.3.2.5 Learning and practices of the advance JSP-servlet and android to make graphs In order to provide graphical report I have to learn advance JSP-Servlet. 2.3.2.6 Learning of JSON(JavaScript Object Notation) In order to interchange the data from android mobile to the server JSON is required. So it should be studied to implement the web services. 2.3.2.7 Knowledge about DBMS or Databases To save the data in database knowledge of DBMS is required so that no duplication of data occurs in the system. 2.3.2.8 Concept of Human Computer Interaction. HCI principles will make the system easy to be used by the user and hence it can play a vital role in the growth of the system in future. 2.3.2.9 Leaning for a development of Real time bug free system. In order to make the system bug free various testing approaches should be learnt and implemented in this system e.g. unit testing. 2.3.2.10

Learning and Practices of SQL Query

To insert the data and fetch it SQL queries should be learnt.

PT0981128



Learning algorithm for smart prediction based on inputs of a month

In order to perform future prediction which is one of the functionality of DET i.e. EF1 one of the best algorithm should be implemented. So learning algorithms will help me out. 2.3.2.12

Learning of Google graph

In order to produce graph in android as well as in web pages Google graph is very much efficient to be used. 2.3.2.13

Learning file handling

In order to save small chunks of data in mobile and access it later on developer needs to learn file handling.

2.3.3 Nature of Challenge As described above the challenges are really going to make the developer a lot from this system. Some of the challenges are really tough to implement e.g. implementing the webservices in this system, showing graphical reports in order to make users understand their profit and loss etc. this system will be complete if and only if all the functionalities given in core (Refer to Section 1.8.1) are completed. This is also one of the major challenges i.e. to complete the system within given time frame.

2.3.4 Challenges in terms of Theory and Software 2.3.4.1 Challenges in terms of Software Challenges in terms of software are small as eclipse has given the developer the frame work, where the developer can work on this project. It has also provided the developer ADT (Android Development Toolkit) on which he has developed the system. And of course it is free of cost. No licensing is required for it. But yes the developer has to register himself to the Google MAP API to get a free developer key which has been used during the development of the system to use Google GPS services. Also while deploying the project developer need to register each individual for a specific key so that they can use the same. Apart from android software like Apache tomcat will be used which is also free for the developer point of view. For the backend process MYSQL database is used and to access it, developer has worked on Wampserver. Wampserver is a tool which provides MYSQL database. To debug the program developer has used emulator so that errors can be rectified as soon as possible.

2.3.4.2 Challenges in terms of Theory The main challenge comes in terms of theory for this system. E.g. how to implement web-application with android device, how to use efficient graph theory for smart prediction,

PT0981128


Daily Expense Tracker how to use graphs, how to customize the options etc. but yes these all problems are the real challenge which the developer is going to really enjoy. Critical Appraisal There were many problems in the current system, which have been sorted out during the development of this system. All the challenges which were listed above were critical and have taken a lot of time of the developer. Not only had this, even to solve a single problem of the user developer had spent a lot of time. The most challenging part was to execute the query on JSP page with the help of emulator i.e. android device. A lot of errors were hampering the system to be completed. Most of them are defined in implementation part of the system. One of the major challenge was to get the data after clicking on the report button and then show them in Listview (just like list in HTML). Initially developer was expecting the JSONObject to return all the values in list but it failed to return so developer had used File Handling for the same. Data from the server is saved in File in android and then it is fetched as per the requirement. This is the reason why developer has given a limited choice to the user to get less than 20-30 no. of records at a time.

PT0981128



CHAPTER 3: LITERATURE REVIEW 3.1 Advanced Preliminary The idea of this system came into developers mind when he was unable to find his expenses when his guardians asked him for the expense report. His guardians asked him to give them the details of expenses which he had done during a month after taking some amount from them. Developer was unable to remember all those expenses. So, he thought why not to develop a system where he can put his incomes and expenses and get the report whenever it is required. Before starting this project he did an extensive research on this topic and found some facts i.e. a lot of system has been developed on this type of project. But all of them had some problem in them which are listed in the problem description section i.e. Chapter 2. Some of the websites and their functionalities are given in section 3.4.1. Also the developer took a lot of ideas from various websites to sort out these problems. For the various options which should be there in the system for saving expenses this website i.e. http://www.nhco.org/budget_packet.pdf is very much helpful. This is a spreadsheet which is provided by NHCO (North Hills Community Outreach) for saving daily expenses.http://www.newhavenlibrary50plus.com/uploads/07_1043_4_Income__Expens es_01-07.pdf this link will also be providing the various options to be saved in the database. Location Marker

3.1.1. Global Positioning System (GPS) tracking The most accurate procedure to find the exact location of a place is by only GPS and if we could attach GPS with Google-Map then the users can find the exact location of anyone and as these devices are on everybody’s android mobile. The developer thought to use the GPS service in the app because he thought it would be easy for users to find out from where they made that expense.

Daily Expense Tracker 3.2 Domain Research As this project is a website as well as android application. The development of this system needs a great research work. With research work done properly one can make out the success or failure of the project, as it provides complete exposure of knowledge, business, human networking, better insights and understanding of the required area. Domain research deals with the whole method of a Website building. Then the developer will include the study of J2EE, XML, Android, SQL Queries. To make the research better, developer has divided it in the following domains: 1. Android Research – The developer should have knowledge of the Android trends and web-applications. 2. Site Development - The primary domain research of project will be choosing the website development methodology as well as android application development. The entire methodology should be clear in mind so as to have clear picture of what next steps to follow for a successful completion of this project within specific time period.

3.2.1 Literature Review on Technical Research 3.2.1.1 Key Concepts of Mobile Technology (As application will run on mobile)

3.2.1.1.1 Why mobile technology? Why not PCs or file system? At the end of 2011, there were 6 billion mobile subscriptions, estimates The International Telecommunication Union (2011). That is equivalent to 87 percent of the world population. And is a huge increase from 5.4 billion in 2010 and 4.7 billion mobile subscriptions in 2009. (Favell, 2012) . From the given facts one can easily understand why we should develop a mobile application. Also in the problem description area I have mentioned many reasons why we should not opt for file system. This is the main reason behind choosing mobile technology.

3.2.1.1.2 Why android mobile technology? Why not some other mobile? 48.5% people in US owns android device. Out of 51.5 all other mobile companies are fighting for their existence (Nielsen, 2012). At the 2012 Mobile World Congress, Google released a startling statistic: There are now around 850,000 Android activations made each day. When close to one million phones are being turned on every day, you're doing something right. Yet, Google and its mobile operating system, Android, still get a bad rap because of different versions coming out. (Scott,

PT0981128


Daily Expense Tracker 2012). Still it is going to play a vital role in the future mobile era. This is why I have chosen android technology to implement this system. Conclusion: The proposed system is an android mobile application which will communicate with web application.

Developers are free to take advantage of the device hardware, access location information, run background services, set alarms, add notifications to the status bar, and much more. This will be helpful to the developer in developing the application.

Libraries

Android provides developers with a set of C/C++ libraries through the application framework itself and some of the examples are mentioned above. These libraries are accessible to the developer for developing feature rich applications.

Android

Android development can only be done in Java. Generally, after compilation of a

Runtime

java program its .class file is executed using JVM but the Android application though developed in java are executed using DVM i.e. Dalvik Virtual Machine.

Linux Kernel

Android depends on Linux kernel for system services such as security, process management.

TABLE 2 ANDROID ARCHITECTURE (LAYER)

3.2.2.2. Security and Permissions Every Android application runs its own process and security among these applications are applied with the help of Linux installations. Android is a safety mechanism restricts processes to perform various operations. Based on the permissions may be that a process can access data from other applications or other operations. This concept will help developers to maintain the security of the application and get all the access permissions for the application. According to the Android mechanism continues, the developer specify access to the Bluetooth function of the device by the application.

Daily Expense Tracker 3.2.2.3 GSM The proposed system uses GSM services to send the message from the app to those whom the users wants to share expense report. 3.2.2.4 GPRS The proposed system can access the internet by GPRS and the speed of net should be 2G or 3G enabled. 3.2.2.5 Wi-Fi (wireless fidelity) The proposed system can access the internet by Wi-Fi also if it there is Wi-Fi connectivity.

3.2.2.6 Design Principle: The design principles that need to be studied in order to provide are as follow: 3.2.2.7 Visibility: Visibility is one of the most important design principles and what it means is that, as and when the user looks on the system screen he/she may feel the possibility for action. The developer will keep an eye on this principal in order to provide better visibility. Conclusion: The developer will provide color schemes in a way that users of this system can easily find suitable content. 3.2.2.8 Feedback: Feedback is the response to the user of the action performed. Most of the feedback has been provided by using Toast in Android and Message box in Web application. Conclusion: The developer has provide appropriate message box (Toast in android) to provide feedback. 3.2.2.9 Constraints: Constraints are some universally accepted conventions which notify some specific actions. Conclusion: 

Inclusion of warning messages to show the errors



For exiting from the application, use of back button as followed by all mobile applications

3.2.2.10. Consistency: Consistency means maintaining similar color schemes, backgrounds, font color and size etc.

PT0981128


Daily Expense Tracker Conclusion: The developer has provided Consistent Colour, Same background, same font size and colour for headings. 3.2.2.11. Affordances: Affordance means expected behavior like cursor of mouse changes into hand symbol on roll-over the link. Conclusion: The developer has provide features like long press key so that user can get the details from the list view. Developer has also provided date picker for the user so that user can select the desired date for reporting. 3.2.2.12. Programming Language Research 3.2.2.12.1. Android  Android OS specific programming, as it is better for customization  Android is well supported with JSP  Android Support with Google-Map and GPS technology  Android has Multi-threading, Handler, Exception Handling, Encapsulation which can be used in the system for various functions like fetching friends data while showing their location on Google-Map. 3.2.2.12.2. J2EE 3.2.2.12.2.1To develop the web application developer has used J2EE. There are a number of patterns that have been identified by the Sun Java Centre for the presentation tier i.e. which is visible to the users. Various patterns are described below in details. 3.2.2.12.2.2Intercepting Filter: Facilitates pre-processing and post-processing of a request. 3.2.2.12.2.3Front Controller: Provides a centralized controller for managing the handling of requests. 3.2.2.12.2.4Composite View: Creates an aggregate View from atomic subcomponents. 3.2.2.12.2.5View Helper: Encapsulates logic that is not related to presentation formatting into Helper components. 3.2.2.12.2.6Service to Worker: Combines a Dispatcher component with the Front Controller and View Helper patterns. 3.2.2.12.2.7Business Delegate: Reduces coupling between presentation-tier clients and business services. It hides the underlying implementation details of the business service, such as lookup and access details of the EJB architecture.

PT0981128


Daily Expense Tracker 3.2.2.12.2.8Service Locator: Multiple clients can reuse the Service Locator object to reduce code complexity, provide a single point of control, and improve performance by providing a caching facility. 3.2.2.12.2.9Transfer Object Assembler: It is used to build the required model or sub model. The Transfer Object Assembler uses Transfer Objects to retrieve data from various business objects and other objects that define the model or part of the model. 3.2.2.12.2.10 Composite Entity: It model, represent, and manage a set of interrelated persistent objects rather than representing them as individual fine-grained entity beans. A Composite Entity bean represents a graph of objects. 3.2.2.12.2.11 Data Access Object: Abstracts and encapsulate all access to the data source. The DAO manages the connection with the data source to obtain and store data. (Satarkar, 2004) E.g. DBAdapter class. Note: More about technical research is given in chapter 4 under Techniques used.

3.3.1 Critical Appraisal of Literature Review The literature review concludes with the final results regarding the development of Android applications. To develop methods and applications of Android architecture follow. The layers in the architecture are discussed above. The developer has been developing the application using open source software. The user can use the app for free for a year by simply downloading and installing the application. The application is developed using the Eclipse IDE and Android SDK for android app. J2EE has been used as framework to develop web application. Netbeans IDE and Wampserver has been used to implement the web application and connectivity to the android app. Only Java programming language has been used to develop Android applications. This gives the developer the main unit and the stage on which to build the application. The current set of Android application development provides positive reasons for developers to develop a game application. The growing number of Android users is another positive aspect to develop the application.

3.3.2 Other academic research areas that need to be looked into are: 3.3.2.1 Human Computer Interaction – to concern with the design, evaluation and implementation of interaction computing systems, HCIU guidelines will be studied.

PT0981128


Daily Expense Tracker 3.3.2.2 Software Methodology – We have different types of methodology to develop a project. In order to make the system best and perfect and feasible, the developer has selected VModels.

3.3.3 Information and Resources 3.3.3.1 Information

For gathering information and user requirements, some technique have to be used which will provide developer an idea and information about the needs of user. To do so there is a need of using data gathering technique. Techniques are listed below: 3.3.3.1.1

Interview

The interview session gives an outline of people response towards the system. Which type of system they require? What should be the option in the expense field? The interview process will be held for a group of users so that more and more opinions will come out for the system. 3.3.3.1.2

Questionnaire

The short, structured and grouped questions according to purpose of the system was very helpful in gathering usage statistics E.g. what and what not to be done. These questioners has been used to collect both qualitative and quantitative data. The questionnaire were distributed to IT personnel who were having some experience and insight into the development of such a mobile applications and web development as well as to the users of the system. The main reason of the questionnaire was to seek and gather all the necessary information that was beneficial for the development of proposed system. 3.3.3.1.3

But in case of interface developer lags behind them. This system also provides almost same functionalities like this system but lags in providing web application, providing location of the user etc. Provides calculator, bar chart, currency converter, other than saving expense but lacks in saving expenses in category e.g. credit, debit, income etc. as well as there is no web application for the same. It provides web interface to save details, but in it we can just save expenses and incomes there is no category wise saving option. It provides graphical layout wherever possible e.g. symbol of cash instead of writing it in textual format. This is handy for the casual user but hard to learn for the novice user.

CHAPTER 4: RESEARCH METHODS 4.1 Primary Research Primary research was conducted by the developer during the initial phase of the system for gathering the information from the potential users of the system so that the developer can make a system that is directly acceptable by its users; primary research was conducted by following techniques.

4.1.1 Techniques used In order to gather the data techniques used in this system are already defined in the section 4.1 and they are questionnaire, interview and by observations.

4.1.1.1. Questionnaire Questionnaire (Refer to appendices for questionnaires) is a part of data gathering technique in which a series of questions designed to gather specific information. Questionnaires will specially be designed for users who would use the system which will include people who are interested in social networking websites. They have few advantages as Questionnaire – 4.1.1.1 Can be used to collect both qualitative and quantitative data 4.1.1.2 Can be distributed manually or electronically 4.1.1.3 Can reach a vast number of people regardless of physical location or geographical dispersion 4.1.1.4 Can be distributed quickly and cheaply 4.1.1.5 Can be used when human and financial resources are not available to conduct interviews 4.1.1.6 Why Questionnaires? As this application is targeting a large number of persons who are going to use the proposed system, so they are enormous in number, so it is not possible to take interview of them because it will be very time consuming. These are some reasons for using Questionnaires4.1.1.6.1. The analysis of questionnaire is most efficient than other techniques as we can draw the graphs and analyse the data. 4.1.1.6.2. It can reach a vast number of people regardless of physical location or geographical dispersion. 4.1.1.6.3.

It can be distributed quickly and cheaply.

4.2.1 Technical Research This part is going to research the proposed system technically means what programming language or database the system is going to use. Some technical research work includes:

4.2.1.1 Platform This part is going to research the proposed system about the programming language, the system is going to use. 4.2.1.1.1 Android Android is the world's most popular mobile platform. With Android you can use all the Google apps you know and love, plus there are more than 600,000 apps and games available on Google Play to keep you entertained, alongside millions of songs and books, and thousands of movies. Android devices are already smart, and will only get smarter, with new features you won't find on any other platform, letting you focus on what's important and putting you in control of your mobile experience. (corp., 2005) 4.2.1.1.1.1 Android OS programming Android powers hundreds of millions of mobile devices in more than 190 countries around the world. Android gives us a world-class platform for creating apps and games for Android users everywhere, as well as an open marketplace for distributing to them instantly. (NA, Android, the world's most popular mobile platform, n.d.)

PT0981128



TABLE 8 ANDROID DEVELOPERS

“Every day more than 1 million new Android devices are activated worldwide.” (NA, Android, the world's most popular mobile platform, n.d.) Android is an open source mobile operating system that is based on the Linux kernel. Using Android, device manufacturers can customize the OS to suit their particular hardware design, thereby allowing them to innovate without limitations. For developers, Android programming uses the Java programming language, and familiarity with the language immediately opens the platform to every Java programmer in the world. 4.2.1.1.1.2 Why Android? Android Support with Google-Map: Android and Google Map both are initiatives of Google itself and for ease of use they

have provided the packaged libraries bundled with Android platform

so use of Google-Map in android application is without compatibility issues, exceptions and well PT0981128

Refer to 4.2.1.1.3 for more language details Android uses Java Language which is an object oriented language enriched with features of4.2.1.1.1.4 Multithreading A program or process can contain multiple threads that execute instructions according to program code. Like multiple processes that can run on one computer, multiple threads appear to be doing their work in parallel. Implemented on a multi-processor machine, they actually can work in parallel. Unlike processes, threads share the same address space; that is, they can read and write the same variables and data structures. . (IBM Team, 2006) 4.2.1.1.1.5 Handler A Handler allows sending and processing Message and Runnable objects associated with a thread's MessageQueue. Each Handler instance is associated with a single thread and that thread's message PT0981128


Daily Expense Tracker queue. When user creates new Handler, it is bound to the thread / message queue of the thread that is creating it -- from that point on, it will deliver messages and runnable to that message queue and execute them as they come out of the message queue. (Google Team, 2007)

4.2.1.1.1.6 Exception Handling Exceptional conditions in traditional environments often arise in situations such as division by zero or “file not found,” and they must be managed with clumsy and hard-to-read constructs. Java helps in this area by providing object-oriented exception handling.

Daily Expense Tracker 4.2.1.1.3 Justification for Selection of Programming Language 4.2.1.1.3.1 Mobile Application

Developer thinks that for developing propose Mobile application Android will be used, as Android is a feature-rich OS programming which contains Exception- Handling, Multithreading, Handlers which will help in developing the proposed project, also it is easy to learn. Android has Google-Map and JSP support as all of these three are backed by Google itself like Google-Map is packaged with the Android SDK so using Google-Map doesn’t poses any unwanted situations and performance issue also they have thoroughly checked and developed functions so it gives a great relax to the developer and maximize the chances of success.  Android is well supported with JSP  Android Support with Google-Map,  Android has Multi-threading, Handler, Exception Handling, Encapsulation which can be used in the system for various functions like fetching friends data while showing their location on Google-Map.  OS specific programming is critically needed as accessing the GPS of mobile device is an OS specific function also mobile notification and alert can only be customized if the developer is using OS specific programming. 4.2.1.1.3.2 Server-Side Application

Developer thinks that for developing proposed Server-Side application JSP-servlet will be used, as J2EE is a feature-rich server-side programming(and all we need from JSP-Servlet is to send and receive the data) which contains Exception- Handling, object oriented concepts, which will help in developing the proposed project. JSP has Android support as these two are backed by Google itself like JSP supports JSON objects that will be responsible for data communication between these two. JSP-Servlet with Android  It is well-compatible with android data sending and receiving with the help of JSON objects which is dedicated for this particular operation.  JSP-Servlet and Android both are well-backed by Google so there won’t be any compatible and performance issues  It has all the capabilities like database connectivity, receiving and sending data, Validations needed for the project.  It is well-supported with Android.

V-MODEL Selected Software Development Methodology: V-model

Advanced waterfall methodology follows V model in development stages. It is an extended waterfall model, adding more details on the validation and verification side. Vmodel gives relationship between each development stages and Testing stages. Reasons for selecting this methodology are: 4.2.3.1.1. The requirements are almost identified and can be changed and DET is such a system whose requirement will go on changing on time to time. 4.2.3.1.2. Any bug can lead back to the initial phase to the model. So it provides a great flexibility to the developer and as the technology used in this system is Android and developer is new to this technology as well, so bugs are inevitable. PT0981128


Daily Expense Tracker 4.2.3.1.3. The Android technology is new and deep, the developer has less experience of development tool as mentioned above so there are more chances of going back to initial phases. 4.2.3.1.4. The developer needs to test at each milestone i.e. for example if the developer is working on reading data from computer, the developer will first have to test it so to perform searching on it. 4.2.3.1.5. The system will be used by a single user so it has to be specific according to the requirement. 4.2.3.1.6. This mobile application has its own specified requirements based on which the developer is going to build the applications, other phases such as design, coding etc. is done with proper testing keeping in mind the requirement specification of the application. 4.2.3.1.7. In v-model developer and tester works in parallel. So developer can test it while implementation and design phase.

4.2.3.2.

Phases of V-Model

This methodology has following phase that developer will follow while developing the system. 4.2.3.2.1. Requirement Analysis- This is the first step in the verification process. During this stage, the developer is not going to discuss how the system is to be built, but it will be a general discussion and user requirements document is put forth. This document will be information regarding the system function, performance, security, data, interface, etc. This document is required by business analysts to transmit system function to users. Therefore, simply be a guide. (NA, Waterfall Model, n.d.) 4.2.3.2.2. System Design-Like the name of the phase suggests, here the possible design of the product is formulated. It is formulated after keeping in mind the requirement notes. While following the documents, if there is something that doesn’t fit right in the design, then the user is made aware of it and changes are accordingly planned. 4.2.3.2.3. Architecture Design-The architecture design, also known as the computer architecture design or the software design should realize the modules and the functionality of the modules which have to be incorporated. 4.2.3.2.4. Module Design-In the module design, the architectural design is again broken up into sub units so that they can be studied and explained separately. The units are called modules. The modules can separately be decoded by the programmer. 4.2.3.3. PT0981128

The Validation Phases of the V model (NA, Waterfall Model, n.d.) Asia Pacific Institute of Information Technology 57

Daily Expense Tracker 4.2.3.3.1. Unit Testing-A unit in the programming system is the smallest part which can be tested. In this phase each of these units are tested. 4.2.3.3.2. Integration Testing or Interface Testing-In this phase the separate entities will be tested together to find out the flaws in the interfaces. 4.2.3.3.3. System Testing-After the previous stage of interface testing, in this phase it is checked if the system meets the requirements that have been specified for this integrated product. 4.2.3.3.4. Acceptance Testing-In the acceptance test, the integrated product is put against the requirement documents to see if it fulfills all the requirements. 4.2.3.3.5. Release Testing-It is in here that judgment has to be made if the product or software which is created is suitable for the user. 4.2.3.4 Justification After some deliberation and discussion the developer settled upon using Waterfall Model for the development of this system. The most tempting factor for selection of V-Model is4.2.3.4.1. Stable project requirements: As in our project most of the user requirements are freeze at the time of PSF so it indicates a stable project requirements and Waterfall methodology completely supports a project which has requirements decided in advance. 4.2.3.4.2. Progress of system is measurable: After each step it produces the documentation and as the structure of our Final year project we need to submit the documentation after each phase so it will be best suitable. 4.2.3.4.3. Strict sign-off requirements: As the developers goal will be to satisfy the user and until the user will be satisfied the developer will be providing the user desired functionalities and proper features so this methodology will be best suitable. 4.2.3.4.4. The emphasis on requirements and design before writing a single line of code ensures minimal wastage of time and effort and reduces the risk of schedule slippage, or of customer expectations not being met. 4.2.3.4.5. In modified waterfall model life cycle phases are permitted to overlap. Because of the phases overlap, a lot of flexibility has been introduced in the modified waterfall model in software engineering. At the same time, a number of tasks can function concurrently, which ensures that the defects in the software are removed in the development stage itself and the overhead cost of making changes to the software before implementation is saved. (Satalkar, 2010) PT0981128


Daily Expense Tracker 4.2.3.4.6. Making changes to the basic design is also possible, as there are a number of phases active at one point of time. In case there are any errors introduced because of the changes made, rectifying them is also easy (Testing can be done). This helps to reduce any oversight issues.

4.3 Critical Evaluation of Research After going through the research work developer was able to find out the in-depth knowledge of the languages which has been used to create the system. This system has been developed on Android OS which supports core java. From core java value is passed into J2EE web application and the returned data is again shown on whenever required. The data base which has been used in this system are SQLLite for offline tasks e.g. Task Manager and MYSQL database for online tasks. Tomcat Apache has been used as a server which communicates between MYSQL database and Android Emulator.

CHAPTER 5: ANALYSIS & DESIGN 5.1 Questionnaire and Interview Questions Refer to appendices for analysis of questionnaire & interview question

5.1.1 Critical Evaluation of Questionnaire and Interview Questions After analysis of questions, the developer concluded on some points which are as followsThe developer has decided to make the system for offline using SQLLITE database and online using MYSQL database. Developer has decided to make the system for Android device with higher configuration than Android version 2.0 and for desktop and other devices with the help of web application. Multiple logging has been provided in a single system. Along with the expense; income, credit and debit will be saved in the system. The developer has decided to provide metaphors for increasing learning ability also the developer will try to provide shortcut-keys, so that users can get quick access of the application. The developer has decided to provide limit on the expenses so that if the users crosses the limit it will generate a notification reminding the user has crossed the limit of the month. The developer will provide an option to upload the profile pic in the system. Developer will be providing both types of reports i.e. graphical as well as textual report. Developer has decided to provide the option to view the location where the expense was saved using latitude and longitude, which will be used in future for visiting the same location using Google map. The developer has decided to provide the future saving prediction feature in this system. Developer will be providing SMS feature in the system so that user can send the expense report to another mobile.

5.4 Critical Evaluation of Analysis After the analysis of the questionnaire the developer has come to the point that to make a system efficient and handy a suitable data gathering technique must be used. And hence after the analysis developer has found answer of many questions on which he was not sure about. Initially the developer had thought of the system which will consist of only saving and that too on webserver but according to the feedback of the users, he decided to make it for saving credits and debits as well and make the system for both offline as well as online. Developer has reached the conclusion because of the feedback of the users which has been gathered by the questionnaire and interview questions.

PT0981128



CHAPTER 5 (PART-2): DESIGN After completing the analysis developer collects sufficient amount of data to model the system. Requirement models allow people to share a common vision of solving the system before the actual implementation. They confirm that the system is flexible enough to accommodate the level of quality of future business needs. Based on the needs of users and the detailed analysis of a new system, the new system has been designed. This is phase System Project, which is the most crucial step in developing a system. This developer will provide Structural Design System normally, the design proceeds in two stages Preliminary or general design and Structure or detailed design Preliminary or general design: In the preliminary or general design, the features of the new system are specified. The costs of implementing these features and the benefits to be derived are estimated. If the project is still considered to be feasible, we move to the detailed design stage. Structure or Detailed design: In the detailed design stage, computer oriented work begins in earnest. At this stage, the design of the system becomes more structured. “Structure design is a blue print of a computer system solution to a given problem having the same components and interrelationship among the same components as the original problem. Input, output and processing specifications are drawn up in detail.” (Anonymous, 2010). So Developer analyzes the requirements and problem and decided to provide Structural Diagram or Detailed Design for these functionalities.

Daily Expense Tracker 5.2.1 Design Methodology Used There are basically two types of design methodology we have: function-oriented and object oriented design. Here developer selects Object Oriented Design Concept.

5.2.1.1 Justification of Selecting OO Design The emphasis on defining software objects and how they collaborate to fulfill the requirements. As a developer uses an object-oriented language (Java) as a platform for this application so that glass is removed from the system needs to be modeled in the form of classes and objects. As a developer result concludes that the DET has to be designed using principles of objectoriented design. To implement the project developer chose to make use of UML (Unified Modeling Language). Why use UML? Developer chooses UML because he has chosen Object Oriented Design Methodology.

5.2.2 Use Case Use case diagram is used to describe the functionality of the system, which mainly include the target users and perspective. It helps in the search for “who is using the system, what are the common scenarios and what they are trying to achieve your goals or” instead of how it will achieve. After analyzing the system, use case are used by developer to document the requirements of the proposed system. Use cases are divided according to different scenario that shows how the system interacts with the user. In the case of use-case we do not use any technical language, so they are easy to understand. Use cases are not used to represent the inner workings of the system, but showing the step that the user will take to perform any specific task. The system requirements will be evident after developing use cases of different modules. Below are additional reasons why you need to indicate use cases for project developers 1. Use Cases helps in finding out the challenges involved in making the Project Planner System and to decide the functionalities to be included in system. 2. Use cases will be helpful for non-technical person to understand the flow of system. 3. Moreover, to give the overview of the system it is necessary to include use case.

Daily Expense Tracker Why Sequence Diagram? Sequence diagrams model the flow of logic within your system in a visual manner, enabling you both to document and validate your logic, and are used for both analysis and design purposes. Sequence diagrams are the most popular UML artifact for dynamic modeling, which focuses on identifying the behavior within your system. FIGURE 21 SEQUENCE DIAGRAM FOR USER LOGIN-SD-01

Mapping the ERD to Relational Database The developer mapped the database designed from ERD to relational database model which

is implemented in RDBMS (MySQL). Mapping ensures that one entity can be stored only in one table and other table can be referenced through that entity by using foreign key or multi-value attributes.Developer found that none of the tables in the database have primary key that uniquely represent a table or multi-valued attributes. Therefore, developer mapped each entity with primary and foreign key.

5.6.2.1 Normalization It is process of efficiently organizing data in a database. It ensures two goals of the normalization process: Eliminating redundant data (Storing same data in more than one table Ensuring data dependencies make sense (only store related data in table).

5.6.2.2 Normalization Criteria: Functional Dependency A functional dependency is denoted by AB , between two set of attribute A and B that are subset of universal relation R which specifies a constraint on possible tuples that can form relation state r of R. The constraint is that for any tuples X1 and X2 in r they have X1[A] =X2[B], they must also have X1[B]=X2[B] Although normalization process is covered when ERD is converted into relations using mapping rules, there are still ways to improve efficiency by following the normalization process.

In the above table to save primary contact details and secondary contact details user needs to save the same data e.g. first name, middle name etc. again and again. Therefore it is well understood that one task have to be repeated for each action. So there is nested relationship present in this table. So there is violation of normalization as data redundancy is there and a particular tuple has more than one non-atomic attributes present in the give un-normalized table. First Normal Form (1 NF) To achieve first normal form developer has to reduce duplicate data and eradicate all non-atomic attributes and nested relationship from the un-normalized table.

Now in each cell there is just one value. Hence 1st NF is achieved here. In the table,{Userid,Contact id} are primary key in the table. Userid uniquely determine some of the attributes. So it determine partial dependency exist here. There is no full functional dependency as Contact id also determine attributes which violates principles of normalization. It determines there is no full functional dependency. Partial dependency Present: Userid{firstname, lastname, fname, gender, doj, dou} Contact id{mobile, village, state, pincode, country, contact type}

Implementation Plan

Developer divide the project into modules and then set the priority for each module and module that has the highest priority, the developer focuses on the first and then proceed to the bottom. Below is the graphical representation shown as a developer divides its work and prioritize the different modules. Priority ranges 1-10 for one with 10 points has the highest priority.

Daily Expense Tracker is a combination of two applications: a) Android Mobile Application b) Web Application Some of the steps that are required to be followed in order to complete the system are: 1. Foremost priority has been given to the Mobile application as the main purpose of this system is to make a mobile based saving app. Then login screen and registration screen has been given the highest priority as without it no one can enter the system. 1.1

Now after registration user will be able to complete his details if he has got time else

he can perform later on. PT0981128



After registration user will be able to perform the tasks given in app.

1.3

Next priority is given to save expense, income, credit and debit as these are the core feature of the system.

1.4

Same priority is given to task manager in android as it also requires a lot of coding

to do. Priority of 7 is given to all types of reports as they would be able to visible only after saving some records. 1.5

Quick expense and account setting has been given same priority i.e. of 6 because

they can be performed later on also. 1.6

User manual has been given the lowest priority because it has been created after the system is complete only.

1.7

Web system and mobile system both have almost same priority as after sending the data from mobile, web system will accept that system and pass it to database. START

FIGURE 32 IMPLEMENTATION APPROACH

According to the flowchart of the developer starts executing the entry and document design, i.e. conducting research and analysis and document then create the database architecture and the implementation is done. Developer started application modules one by one and integrates all PT0981128


Daily Expense Tracker modules as one. The result of the application will not work as input to the next phase of testing and after testing system is ready to be implemented in an organization.

6.1.1 Implementation Methods Test Driven Development Advantage

Avoid re-testing of codes and performed in less time. Disadvantage Testing require efficient approach

Pair Programming

Source Code Control & Build

Code typing and reviewing take place simultaneously Loss of productivity as require two people

Least complex way to integrate the project Sometimes may result in redundancy

Incremental Coding Approach Simplest method to follow a linear approach. As it is not iterative so it creates chances of Risk.

Justification of selected implementation method Developer analyzes the advantages and disadvantages of the above implementation methods and found that Test Driven Development method is best suitable for the project implementation. As it avoid retesting of codes and also favors the implementation of V-Model.

6.2

Program Standards Followed

6.2.1 Naming Convention 

Developer

uses

English

descriptors

that

Implementation of Modules

Save Expense Module Implementation

Objective

This is the one of the main functionality of this system which will save all the daily expenses which the user will like to save. Along with the expenses the location of the place using GPS technology will also be saved so that if the user wants to know from where they saved this detail they can easily know. User can save credits, incomes and debits detail as well in this system.

Problems Occurred Graphical Report: when there is no internet connectivity or internet is slow then android activity which is drawing the graphical report crashes and hence user has to login again. Solution The developer tried to rectify the problem by using try and catch method to prevent system in from being crashed and show proper message.

Problems Encountered

Solution: Developer changed the name of Open() method in DBSql class to OpenConnection() by doing refactoring the whole name. The changes were made in the java File associated with it. But wherever that name was used in JSP file was not refactored. And was not showing error too. But after running that jsp file user encountered the following error. This error was resolved by the developer by changing the name manually.

Functionality not implemented

Upload/Downloading File(Image) from Mobile: As it is mentioned that DET will work on both mobile and web but it is unable to provide Uploading and downloading features on mobile as files may be very large and unable to support mobile data and developer is successful in getting path but unable to maintain contact with server for long time. Code for implementing file upload feature For Uploading/Downloading

FileConnection fileConn = (FileConnection) Connector.open(url, Connector.READ); InputStream fis = rivate void displayAllRoots() { PT0981128

System.out.println(e.getMessage()); } catch (SecurityException e) { fileConn.openInputStream(); long overallSize = fileConn.fileSize();


Daily Expense Tracker setTitle("[Roots]"); deleteAll(); Enumeration roots = rootsList.elements(); while (roots.hasMoreElements()) { String root = (String) roots.nextElement(); append(root, null); } currentRoot = null;} private void openSelected() { int selectedIndex = getSelectedIndex(); if (selectedIndex >= 0) { String selectedFile = getString(selectedIndex); if (selectedFile.endsWith(FILE_SEPARATOR)) { try { if (currentRoot == null) { urrentRoot = (FileConnection) Connector.open("file://" + selectedFile, Connector.READ);

int length = 0; byte[] filedata = new byte[0]; while (length < overallSize) {//converting the selected file to bytes byte[] data = new byte[CHUNK_SIZE]; int readAmount = fis.read(data, 0, CHUNK_SIZE); byte[] newFileData = new byte[filedata.length + CHUNK_SIZE]; System.arraycopy(filedata, 0, newFileData, 0, length); System.arraycopy(data, 0, newFileData, length, readAmount); filedata = newFileData; length += readAmount;} fis.close(); fileConn.close(); //here u can write a code to connect with the server for sending the selected file } catch (Exception e) { //showAlert(e.getMessage()); } finally { }

Explanation (What developer is trying to do)

Developer developed the code to download and upload the file from the web server. So to accomplish it he made a class called FileSelection having the property to find the actual path where the file is stored in mobile to upload. File Selection is calling execute() function when select the file. Execute() will help in append the file to the mobile screen and show the actual path and send data length to byteConverter where it will check length of data and send to the server for uploading. Developer is successful in searching the path and covert data to byte code but unable to communicate the server to the send the large bunks of file and download and save to mobile.

Upload Image) for Profile: Developer had thought to provide the feature of saving profile pic on the device app. But he was not able to do so because after clicking the photo from the camera he was not able to save it in database. Code for implementing image upload feature For making image the profile pic.

InputStream is = getResources().openRawResource(R.drawable.flower);//to get the pic which is already saved in app. bmp = BitmapFactory.decodeStream(is); wall = (Button) findViewById(R.id.bSet); take = (Button) findViewById(R.id.bTake); pic = (ImageView) findViewById(R.id.ivImage); Explanation (What developer is trying to do)

Developer is trying to find out the path of gallery and save the pic downloaded from the database to the sqllite database. And use it future.

Implementation of Complex Modules

PT0981128


Daily Expense Tracker In the Primary research developer found that all the users wants to use the mobile version of this app. So Developer decided to develop this module after completing the web module. Android platform. Android is the world's most popular mobile platform. With Android you can use all the Google apps you know and love, plus there are more than 600,000 apps and games available on Google Play to keep you entertained, alongside millions of songs and books, and thousands of movies. Android devices are already smart, and will only get smarter, with new features you won't find on any other platform, letting you focus on what's important and putting you in control of your mobile experience. (NA, Android, n.d.) Problem Faced By Developer in Developing This Module 

Main task is to maintain the consistency between Web and Mobile Module so Developer Design the whole system but how to maintain the integrity.



How to display data from server to mobile screen.



How to make the mobile work as offline system too.



Draw graphical report on mobile.

Solution 

Developer had initially created separate jsp files to handle request send by web page as well

as android app but later on he realized that same file can do the work for both after making a little modification. E.g. instead of redirecting all requests to other pages developer has checked whether the request is coming from web page or android app. From android app one more parameter has been sent which is used to find from where the request is coming. And if the request is coming from android there is no need to redirect to other pages. Developer has just provided the output as response.getWriter().print(“insert success”). For more information please check the file CompleteRegistration.java line no.117. Code Snippet: if (from.equalsIgnoreCase("android") & i > 0) { response.getWriter().print("userid"); } else { response.sendRedirect("index.jsp"); } 

Another solution which developer has found is the use of jquery. With the help of jquery user can pass the data to the servlet and get the output on the same file. Which has been

PT0981128


Daily Expense Tracker shown in toast in android and Toast like alert box in web page. There is no need to redirect to other page and hence the web page is very light to be loaded. 

Developer first Stores all the data on JSP page and then read data by input stream reader, here it stores data in byte form and then data is appended from byte array to stringbuffer, which is then finally displayed on screen. Pseudocode: START Read Data from Mobile form Pass data to jsp page Call desiredClass servlet Return data in NameValue Pair In mobile class read data through input stream Store all data in byte array in File Read data from array till it ends Now show the data in ListView one by one. Data displayed on mobile screen STOP

Problem with Graphical Reports: Developer finds in research that users want reports in both format texts as well as graph and to implement the graphical module developer has to do extensive research on it as java doesn’t provide any inbuilt tool for that and developer has to use third party tool to implement this functionality Solution Developer Uses third party tool Google Graph API to implement this module

6.10 Conclusion Developer goes through many of the problems while development stage and most of the problems are rectified. As developer uses some third party tools such as e-mail, Google chart, which is currently in demo for display purpose. Developer has made the system in such a way so that if it is not working any tools 3rd party it will not give the error and the user can continue to use the system on the Internet. Now the system is ready to be in the testing phase to finally find errors which still exists in the system.

PT0981128



CHAPTER-7 TESTING 7.1 Test Plan Testing is the process of Identifying defects and correcting errors, where a defect is any variance Between Current and expected result. It a specific part of the software development to check the robustness of software. It is used to evaluate-the reliability, usability, maintainability of software. Why to do Testing: •

Identify area of weakness in the system.

•

Establish degree of quality of the system.

•

Free from bus and system errors.

•

Improve consistency and efficiency of the developed system.

The strategy to cover the full system test of “Daily Expense Tracker” is described above. Developer just uses the system documentation to cover all the test cases, procedures and design. Some Users involve in this testing phase are Students of APIIT, Developer himself and the Group Members so that changes can be made according to user choice and a quality system can be provided to the user as the success of any system depends on the its quality and quality is depends on the customer satisfaction. The type of testing that is to be carried out is as follows 1. Unit Testing (White Box Testing & Black Box Testing) 2. Integration Testing 3. System Testing

4. User Acceptance Testing Point of Contact for Troubleshooting Purpose Name: Durgesh Kumar Designation: Project Developer Contact Number: +91-7206391375 Email id: [email protected]

PT0981128


Daily Expense Tracker USERS INVOLVED IN THE TESTING 

Durgesh Kumar (System Developer) is the test manager and analyst for the Project Planner System. Most of the tests are conducted by the developer itself. The other user which involved in the testing are mentioned in the test cases.



The implementation of test data along with reported errors and measures taken also listed below in the test cases.

PASS/FAIL CRETERIA The system must justify certain standard requirement for system pass/fail criteria. Some of the identified requirements are:    

Daily Expense Tracker modules must work properly Response time of the system should be less than 30 sec GUI must be consistent and follow the HCIU principles Administrator must have control over the system and can do anything he wanted to do.

7.2 Unit Testing The primary goal of unit testing is to take the smallest piece of testable software in the application, isolate it from the remainder of the code, and determine whether it behaves exactly as you expect. Each unit is tested separately before integrating them into modules to test the interfaces between modules. Unit testing has proven its value in that a large percentage of defects are identified during its use. (Unit Testing, 2013) This testing is usually performed by the software developer while developing the software. The set of test cases output and input will determine whether it is according to the requirement or not. Unit testing is divided into two components White Box (also called Logical Testing) and Black Box (also called Functional Testing). Justification for Using Unit testing in the project It is done at the initial level. It is easy to locate any error easily as the size of module is enough. And it also avoids confusion and interaction of multiple errors in different module of the project.

As when user saves the record from the web application then there is no option to find the location with website. Save location facility is only available for the mobile as GPS is only present in the mobile. So Developer found that it is not possible to show the route to those expenses which are saved from web app. User is advised not worry for the same as it’s not a major fault. It can be rectified if the user saves the expenses only from mobile application that too after turning ON the GPS. Review Test Case for failed Obligations Module

Cyclomatic complexity V(G) can be computed as: V(G) = E – N + 2 . Where N is the number of nodes of the control flow graph and E is the number of edges in the control flow graph. For the CFG of example shown in above fig, E=21 and N=16. Therefore, the cyclomatic complexity = 21-16+2 = 7.

7.3 Integration Testing

PT0981128


Daily Expense Tracker It is a logical extension of the unit test. In its simplest form, the purpose of unit testing is to validate the operation of each unit but gives little area to determine whether the interaction between units operate properly. So here integration testing come into existence.

7.3.1 Integration Approach The developer is following the Top-down integration approach. This approach is followed where control and interference are the most important part of the project. DET demands proper flow on the actions. There is restriction on user on the access of resources. So to implement this, a managed control is required for which Top-Down Integration testing is most suitable. Whereas Bottom-up approach is not followed as it is most suitable at structural and machine level. (Aggarwal, 2008)

CHAPTER-9 CONCLUSION 9.1 Limitations of Daily Expense Tracker 1. Platform Dependency in Mobile: This system is specific to some of the Java enabled mobile having Android OS. 2. While using some of the functionalities of this system e.g. graphical report internet connectivity is required. 3. Messages to other mobile will not go automatically as charges from the users account will be done for messaging. 4. There is no option to download or upload pic from this app.

9.2 What more could be done if more time was given? 1. If more time is given developer will definitely focus on enhancing the project’s scope and services. 2. The very first thing developer will provide Bluetooth assistance to add data to the mobile as well as desktop to see the reports. 3. Jasper Reports would be provided 4. Developer could provide the reports converted into pdf format 5. Minutes of meeting can be provided after every meeting. 6. Offline and online synchronization of data could be enhanced more. 7. Future prediction functionality could be more accurate. 8. Graph theory could be implemented for searching of reports. 9. GUI of the system could be enhanced more.

9.3 Future Enhancements 1. Enhanced GUI of android application: It will be changed in platform to a more open source platform so that it can be in reach of mobile users. 2. Auto Reminder: A reminder in Mobile which can store data in mobile so even if user is not connected alarm of mobile can ring and sent notification to user. 3. Finance Module: Right now developer implements only task management module but this can be integrated with finance which includes resource management, which will be an addon for this project. 4. Resource Module: Due to time constraint Developer isn’t able to develop the Resource Module in which System will maintain the Resources used in completing the Tasks assigned by user. 5. Stenography: Developer wants to use stenography concept to secure data theft from users account. 6. Updating Version: Developer developed this module on J2EE, in future he would like to upgrade it to Struts and also integrate spring to enhance the functionality of this system. 7. Chat Module: Developer like to integrate chat module so to give this system a nice look, so that user who are saving expenses and using this system can chat with each other.

PT0981128


Daily Expense Tracker 9.4 Conceptual Challenges: 1. Implementation of project with the technologies like J2EE (JSP, Servlet) and Android. As J2EE implements security so it was a tedious task to implement modules with the technology. 2. Implementing security in the system as it is important pages don’t show their exact property and the path to which they were redirecting. 3. Synchronization of mobile and web was a task to be handle efficiently as user is creating different session at a particular time so there may be chances of data redundancy which is effectively handle by this system. 4. Using third party tools like Google Graph to implement report functionality of system 5. Managing screen rotation in android so that data could not be lost while saving. 6. Use of file handling to manage session in android because after rotation of screen each time a new activity is loaded and to give it new session is typical. Apart from this the biggest challenge developer face is integration of different pages in the DET. As it consists of many activities interlinking with each other and can cause problem in handling the user’s activity. Apart from computational challenges developer faces challenge of innovativeness as it a customized project for users so developer spent a lot of time to research the modules specific to suite the user needs. Testing has been elaborated specially unit testing thoroughly. As it is a customize project so developer also need to take care of the limitation of the project.

9.5 Learning Experience From the start to the end of the project developer get the opportunity to learn new skills, acquire knowledge of the system development phase. Few of the experience are 

Time Management: Time management is the foremost developer learned throughout the development of project. Developer learns how to manage time even in the most stressful time during the project. It gives developer a working experience on how to plan our time to obtain the task.



Tools and Techniques: Developer learned the most competitive language present in current market J2EE and Android for his project which gives developer a competitive edge in the market.



Project Management and Communication Skills: Various project management methodologies are applied to the proposed system. From here developer learn how to handle the tasks and deliver a quality product in the end.

 Work Flow Process: Developer learns how the work flows in an android, how to manage activity, how to pass data from one activity to other, how to manage screen rotations, how to send request and get response from web server etc.

PROJECT PROPOSAL FORM Title: Daily Expense Tracker Please describe the type of the system being developed. Daily Expense Tracker is an Android based software, which helps you to TRACK your every penny waste on different cost heading. It saves your money, saves your time - organizing your finances. Helps you to budget better by giving you control of your money. It provides complete solution for students, businessmen and for all of them who feel laziness in tracking down their daily expense and those who know how to use a simple android mobile. You can enter your own items and save them in the system along with their cost and quantity. This is software which has been made for tracking down the expenses which you do daily. This software is operable 24x7 hours. This can be used to schedule your budget also. It enables you to watch out the future saving based on the saving done till date. It provides backup for the users so that if the device is destroyed accidently then the data can be recovered from the server itself with the help of username and password. If you forget your device to take with you and you need an urgent use of the data saved on the device then it can be done with the help of website on which data has been synchronized. You can plan your daily expense to do with this software. You can provide limit to some of the items say, you have put a limit on petrol as 500 and you are exceeding the petrol limit say 600 then automatic notification will be sent on your mail as well as on the device screen. The system provides both offline as well as online facility. If you have no internet facility then there is no need to worry, you can simply use the system without internet and when you get the internet facility you can synchronize your data with the server. Reports will be sent on your mail as per your preferences made in the system setting. Who is system being developed for? Anyone, ranging from home users to office user and any businessmen interested in tracking their daily expense. People who want to schedule their budget. A person who wants to find his saving at the end of the day, month and year, as well as for him who wants to see his progress based on today’s saving. The system can be used by them who are careless in handling the device e.g. who usually finds their device stolen, broken etc they can recover their data from the server. On the other hand, the system could be used to guide the user for being more expensive by providing notifications. Why is such a system required? We are in such an era today that our most of the work has been shifted to computer; we are surrounded by the computer system which has made our memory powerless. We feel hard to jot PT0981128


Daily Expense Tracker down every expense we do every day due to lack of time and we used to forget the expenses made during the day. We used to forget whom we have to give money and how much as well as from whom we have to get. For this scenario this system is very much helpful to the user as you can write down the name and money at the same time. There is no need to memorize everything basically cost related tasks and expenses made during the course as this system provides you with all these facilities. If you lost your device then the data can be easily downloaded from the website and hence you can be saved from a disaster. What will be the main challenge for you in building the system? The primary challenge in building this system is customizing the various user requirements based on their category e.g. students, businessmen, home users etc. the data which has to be customized should be gathered from various users. Some off the other challenges are i.

Synchronization of data with the server: the data which is in the device should be synchronized with the server so that the user can access it from anywhere. ii. Offline and online facility: providing both of the facility to the user so that user will feel free to work with this system. iii. Graphical data: Showing graphical data to the user so that user can understand his/her expenses easily. iv. System portability: making the system to be portable on various android devices. v. When the screen orientation is changed the data provided to the system is lost which has not been saved in android application hence managing this screen orientation to be compatible with the system is one of the challenge in developing this system. vi. Managing reports and sending them on mail: various types of reports will be made and sent to the user’s mail so that user can get a clear and more detailed view of the reports. vii. Apart from these one of the challenges is making the GUI follow HCI principles. viii. Future saving prediction: on the basis of saving of the week/month predicting the future savings is one of the challenges to implement. What new ideas and theory will you need to learn to build the system? In technology I need to learn android technology which is being widely used in the market today. To complete the above challenges I will have to learn how to synchronize the data with the server, how to provide online and offline facility that too with mobile device. To create graphs I need to learn graphs and use its component to show the data on cursor movement. I will have to use the best algorithm to develop the graph as well as do the future prediction. To make the prediction I need to learn cost-benefit formulas and implement it in this system. <<<<<<<<<<<<<<< End of PPF >>>>>>>>>>>>>>>

PROJECT SPECIFICATION FORM A. Name : Durgesh Kumar Student ID: PT0981128 Title : Daily Expense Tracker (DET) Supervisor: Mr. Ankur Singla B. Brief description on project background.(.i.e. problem context, rationale, description of problem area, nature of challenge) Brief Description of Project Background: Firstly question arises what is this DET? The system itself defines its task, “Daily Expense Tracker” means it is a tracking system which will save our daily expenses, credits i.e. from whom we have to get money, debit i.e. to whom we have to give and how much. Not only this but almost every work which involves transaction of money will be stored in this system and based on the data stored this expert system will give some predictions and reports. Project background: There are so many people who used to maintain dairy for their daily expenses so that they can use it for future. There are some people who used to remember their PT0981128


Daily Expense Tracker expenses but there counting is very less as in today’s scenario where there is no time for an individual to eat properly, sleep properly walk with their belongings for a moment then think for a moment how can they maintain their dairy which will again put a burden on their mind to remember those activities which they have done. Those people who want to save their daily expenses in such a place which will be handy to use. One of the most appropriate places to store the data is the mobile phone. Also in the dairy system, if the dairy is lost then it will be a heart locking situation. Problem Context: as almost all users are connected with each other with mobile, the trend to save small pieces of data into mobile in logs, notes, reminders has increased. So users need a system which will make automatic calculation based on their expenses. It’s not so that there does not exist any system for the same but there are some problems which are listed below. There is lack of research and functionalities in the current system as well. We are in such an era today that our most of the work has been shifted to computer; we are surrounded by the computer system which has made our memory powerless. We feel hard to jot down every expense we do every day due to lack of time and we used to forget the expenses made during the day. We used to forget whom we have to give money and how much as well as from whom we have to get. For this scenario this system is very much helpful to the user as you can write down the name and money at the same time. There is no need to memorize everything basically cost related tasks and expenses made during the course as this system provides you with all these facilities. If you lost your device then the data can be easily downloaded from the website and hence you can be saved from a disaster. Description of Problem area:         

No offline-online data synchronization: Current system only provides the either of the offline or online data saving feature. If the internet is not working then online system will not work and hence the user has to suffer a lot. Slow data retrieval while searching: Data retrieval is slow in case of online systems depending upon the speed of internet connection. Hence user will have to wait for a long time for even searching a name of the item. Lack of security: When the system supports only offline task then if the data is deleted or the mobile gets stolen all the data will be lost and user has to suffer again. No backup and recovery for the data: there is no backup and recovery facility in the current system. That means once the device is lost or file is corrupted then there is no way to recover it. Manually schedule: In traditional file systems there was no option of scheduling along with tracking budget and provide notification when necessary. Report generation: The report generation format is not up to the level. Only data which has been saved are shown. No customized report is possible. No Prediction: The current system does not provide us any facility to view the future benefits. No prediction is there. No option to add items in customization: There is no option to add our own customized items as per our requirement. Only one session per mobile: There is only one user account in the current system. If there exists multiple users to work on the same mobile then there are no criteria for that.

Recommended Solution: The solution for the current system is to develop a system which will sort out all the above problems. The solution can be provided via four ways  Via Desktop Application  Via Web Application  Via Mobile Application  Via combination of Mobile and web services If the system is developed for the desktop application then each system of the user must be installed with the new software, this would again been a cumbersome activity. PT0981128


Daily Expense Tracker If the system will be made web based then user needs to access the internet for each time they have to save the data. It’s havoc for the user. Any user cannot afford this if they to save a small chunk of data they will not wish to login to the internet again and again. If the system is made for the mobile i.e. mobile application then it would be a perfect system for the user as user can easily save their expenses while on road, bus or say wherever they are. But this system has lot problems in it e.g. If the mobile is lost or database is crashed then user can go out of mind. If the system is made via the combination of Mobile and web services then it would be a perfect system. This system is combination of both web services and mobile services. Rationale: as mentioned above we clearly find out that there is a need of such a intelligence system which will save a lot of money and time behind searching a particular data of a particular person based on mobile devices. To provide security and services to the layman so that they can save and fetch their expenses whenever they require it is one of the main mottos of this system. Tangible benefits  One time investment: Users will have to invest their money for just once to use this system on android mobile but to use the web services they will have to pay according to the plan.  Saving on Internet Data usage: there is no need to start the internet all the time when you want to save the expense details as this can be done offline. User can synchronize their data during their off time i.e. just once in a day or a week internet is needed. Hence wastage of data usage can be saved.  Accessibility of system: System can be accessible anywhere if the user has got the mobile. If mobile is not with him/her then the system can be accessible with the help of website if the user has a login id and password.  Reduces the stress: this system will directly reduce the stress from the user as the user will not have to calculate each and every thing ex. How much they have balance in their hand? Etc.  As this system is using external server to save the user details so there is no need to give an option to backup and recovery the data this choice will be given to the admin. Intangible benefits:  Economic Benefits: with the help of this system we can save our lot of money which goes in waste land due to the lack of planning.  Save time: this system will save our time as we can do hours of work in a minute. E.g. if we need to search a person whom we have to give money from our notebook then it will take hours if there are thousands of record but with the help of this system it will take less than a minute. Target Audience Anyone, ranging from home users to office user and any businessmen or professionals interested in tracking their daily expense. People who want to schedule their budget. A person who wants to find his saving at the end of the day, month and year, as well as for him who wants to see his progress based on today’s saving. The system can be used by them who are careless in handling the device e.g. who usually finds their device stolen, broken etc they can recover their data from the server. On the other hand, the system could be used to guide the user for being more expensive by providing notifications. All types of users aging more than 13-14yrs. This system will be used by administrator as well who will be manage the website and create a back-up plan if required. Challenges in the Projects: The primary challenge in building this system is customizing the various user requirements based on their category e.g. students, businessmen, home users etc. the data which has to be customized should be gathered from various users. Some off the other challenges are  Saving data on external database other than SQLLite from android device: the data which is in the device should be synchronized with the server so that the user can access it from anywhere.

Offline and online facility: providing both of the facility to the user so that user will feel free to work with this system. Graphical data: Showing graphical data to the user so that user can understand his/her expenses easily. System portability: making the system to be portable on various android devices. When the screen orientation is changed the data provided to the system is lost which has not been saved in android application hence managing this screen orientation to be compatible with the system is one of the challenge in developing this system. Managing reports and sending them on mail: various types of reports will be made and sent to the user’s mail so that user can get a clear and more detailed view of the reports. Apart from these one of the challenges is making the GUI follow HCI principles. Future saving prediction: on the basis of saving of the week/month predicting the future savings is one of the challenges to implement. Knowing the user- To understand the spending habits of people. The manner in which they spend the money, decisions they take before spending on something. Other challenge would be of how to make this application make effective to make people use the application, as some people would consider the application as ineffective in respect to the amount of time they give in use of the application. Interaction design and coding is also one of the major challenges of this system.

C. Brief description of project objectives. (I.e. scope of proposal and deliverables) Project objectiveThe objective of this system is to design such a system for users which will resolve the problems related with daily expenses and save a lot of money by providing them necessary notifications and by showing their profit or loss based on daily expenses.

Users those who will test the system and give evaluations will also be involved in whole process of development of the system. These users can be: Students, Random Online Users having internet accessibility, Business People, Administrator E. Academic research being carried out and other information, techniques being learnt. (I.e. what are the names of books you are going to read / data sets you are going to use) Domain Research: As this project is a website as well as android application. The development of this needs a great research work. With research work done properly one can make out the success or failure of the project, as it provides complete exposure of knowledge, business, human networking, better insights and understanding of the required area. Domain research will deal with the whole method of a Website building. Then the developer will include the study of J2EE, XML, Android, SQL Queries. To make the research better, developer has divided it in the following domains:  Android Research – The developer should have some knowledge of the Android trends and web-services.  Site Development -- The primary domain research of project will be choosing the website development methodology as well as android application development. The entire methodology should be clear in mind so as to have clear picture of what next steps to follow for a successful completion of this project within specific time period. Other academic research areas that need to be looked into are:  Human Computer Interaction – to concern with the design, evaluation and implementation of interaction computing systems, HCIU guidelines will be studied.  Software Methodology – We have different types of methodology to develop a project. In order to make the system best and perfect and feasible, the developer has to research for the methodology which best suited the mobile based application. Information and Resources Information For gathering information and user requirements, some technique have to be used which will provide developer an idea and information about the needs of user. To do so there is a need of using data gathering technique. Techniques are listed below:

PT0981128


Daily Expense Tracker  Interview The interview session will give an outline of people response towards this system. Which type of system they require? What should be the option in the expense field? The interview process will be held for a group of users so that more and more opinions will come out for the system.  Questionnaire The short, structured and grouped questions according to purpose will be very helpful in gathering usage statistics i.e what and what not to be done. These questioners can be used to collect both qualitative and quantitative data. The questionnaire will be distributed to IT personnel who having some experience and insight into the development of such a mobile applications and web development as well as to the users of the system. The main reason doing the questionnaire for this project will be to seek and gather all the necessary information that might be beneficial for the development of proposed system. Books:  Android application development for dummies-Donn Felker  Beginning Android Application Development -Wei-Meng Lee  Human Computer Interaction- Alend Dix, Janet Finlay, Gregory D. Abowd, Russell Beale.  Data Structure- Schaum’s outlines, TMH Website:  www.W3Schools.com  www.wrox.com  www.eclipse.org.in  http://daily-expense-tracker.fyxm.net/  http://itunes.apple.com/in/app/daily-expense-tracker-income/id502080453?mt=8 People:  Online Users  Mobile users  Students  Business People Technical Research: For successful development of any project, developers programming and technical skills must be sound as without this the functionality of the system could not be achieved. Some technical research work includes: SQLlite Database It will be used by developer as backend for his project or websites. MYSQL Database It will be used by developer as backend for the online website and to provide synchronization of data in mobile and web. SQL Query SQL Query will be used for interacting with DBMS in order to fetch the data or maintain records in backend databases. XML: XML is a light weight database used to transport and store data, contains its own tags as well as we can even add our own tags. This will be used for storing and fetching the images and other data. File Handling: This will be used to save login information and small chunks of data whenever required. Android Technology To run the system on android platform developer needs to manage the memory as well as learn more about this technology. F. Brief description of the development plan for the proposed project. (i.e. which software methodology and why, the major areas of functions to be developed and the order in which developed) PT0981128


Daily Expense Tracker Methodology refers to the set of methods or procedures by which developer is going to achieve the goal of project. To start a project developer has to identify a suitable software methodology to develop the system. System development methodologies are promoted as a means of improving the management and control of the software development process, structuring and simplifying the process, and standardizing the development process and product by specifying activities to be done and techniques to be used. It is often tacitly assumed that the use of a system development methodology will improve system development productivity and quality. However, there is little empirical evidence to support this assumption. That’s why we use system development methodology. Selection of methodology is a vital activity in software development phase as all other steps of the system will be dependent on this step itself. Each and every phase of development methodology helps developer to determine what to do, how to do and when to do in this project. Methodology also tells us how to handle the challenges and how to solve the problems. Selected Software Development Methodology: V-model It is an extended waterfall model, adding more details on the validation and verification side. Vmodel gives relationship between each development stages and Testing stages. Reasons for selecting this methodology are:  The requirements are almost identified and can be changed and DET is such a system whose requirement will go on changing time to time.  Any bug can lead back to the initial phase to the model. So it provides a great flexibility to the developer and as the technology used in this system is Android and developer is new to this technology as well, so bugs are inevitable.  The Android technology is new and deep, the developer has less experience of development tool as mentioned above so there are more chances of going back to initial phases.  The developer needs to test at each milestone i.e. for example if the developer is working on reading data from computer, the developer will first have to test it so to perform searching on it.  The system will be used by a single user so it has to be specific according to the requirement.  This mobile application has its own specified requirements based on which the developer is going to build the applications, other phases such as design, coding etc is done with proper testing keeping in mind the requirement specification of the application.  In v-model developer and tester works in parallel. So developer can test it while implementation and design phase. This methodology has following phase that developer will follow while developing the system.  Requirement Analysis-This is the first step in the verification process. It is in here that the project and its function are decided. So a lot of brainstorming and documentation reveals what all will be required to produce that program or product. During this stage the developer will not be going to discuss how the system is going to be built; it is going to be a generalized discussion and a user requirement document is put forth. This document will carry information regarding the function of the system, performance, security, data, interface etc. This document is required by the business analysts to convey the function of the system to the users. So it will merely be a guideline.  System Design-Like the name of the phase suggests, here the possible design of the product is formulated. It is formulated after keeping in mind the requirement notes. While following the documents, if there is something that doesn’t fit right in the design, then the user is made aware of it and changes are accordingly planned.  Architecture Design-The architecture design, also known as the computer architecture design or the software design should realize the modules and the functionality of the modules which have to be incorporated.  Module Design-In the module design, the architectural design is again broken up into

The Validation Phases of the V model  Unit Testing-A unit in the programming system is the smallest part which can be tested. In this phase each of these units are tested.  Integration Testing or Interface Testing-In this phase the separate entities will be tested together to find out the flaws in the interfaces.  System Testing-After the previous stage of interface testing, in this phase it is checked if the system meets the requirements that have been specified for this integrated product.  Acceptance Testing-In the acceptance test, the integrated product is put against the requirement documents to see if it fulfills all the requirements.  Release Testing-It is in here that judgment has to be made if the product or software which is created is suitable for the user.

Daily Expense Tracker G. Brief description of the evaluation and test plan for the proposed project. (I.e. what is the success criteria and how will be evaluated & implementation will be tested, indicate the estimated size of the demonstration/test database) Evaluation involves judgment of the quality of an object against certain specified criteria. Whether evaluating fine wine, art, or an educational software program, the evaluator is making observations or collecting information, and comparing or interpreting that information in order to make a decision as to the value of that object. Formative evaluation is the process of evaluating the effectiveness and efficiency of multimedia/Partial system during the development process. Main points of formative evaluation are as follow:  It is done at different stages of development- After each milestone developer will be doing formative evaluation to check whether the system is going to made according to the user or not.  To check that the product meet user’s needs-as mentioned above it is done to check whether the product is meeting the user’s need or not.  Focus on the process-as mentioned earlier this evaluation is done at process level. Summative evaluation, in contrast, is the evaluation of the completed product. The worth of a program or the overall effectiveness of the finished software product is judged.  To assess the quality of a finished product-it is done to check whether the complete system meets the requirement or not if yes then whether its quality is good or not.  Focus on the results-its main focus is on the final result. Effectiveness of the system:- Developer will be choosing from observational and co relational methods for demonstrating whether desired effects occurred, and quasiexperimental and experimental designs for determining whether observed effects can reasonably be attributed to the intervention and not to other sources. Evaluation on Success Criteria: Easy navigational features  User is able to read data from mobile  User is able to store his/her expenses in his/her mobile  User is able to search expenses on various parameters  User is able to save daily expenses, incomes, credits and debits  User is able to view the reports based on expert system  Multiple users are able to login with the same application  User is able to put limitation on his budget i.e. expenses should not be more than this amount. Evaluation can be done using any of the four strategies  SCIENTIFIC-EXPERIMENTAL MODELS  MANAGEMENT-ORIENTED SYSTEMS MODELS  QUALITATIVE/ANTHROPOLOGICAL MODELS  PARTICIPANT-ORIENTED MODELS Testing is done throughout the implementation phase and even in design phase. Various testing techniques are as follows:Black-Box Testing: What is the application going to do is tested here, but how it will do is not an issue to concentrate upon in Black Box testing. Testing without knowledge of the internal workings of the item being tested is called Black Box testing. Black Box testing method is applicable to all levels of the software testing process:  System Testing: Testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic.  Integration Testing: Testing in which modules are combined and tested as a group. Integration Testing follows unit testing and precedes system testing. For ex, after testing each unit individually all the modules should be combined and then tested that if any module is interrupted by other or may be not working in integration with another. Like searching and updating module working together or not.

Acceptance Test: Acceptance testing is a test conducted to determine if the requirements of a specification or contract are met. It may involve chemical performance tests also. White-Box Testing: This application is having complex functionality which involves white box testing. White Box testing is mainly concerned with the internal functionalities of the application. Testing based on an analysis of internal workings and structure of a piece of software. The tests can be conducted based upon the designs, programmed functionalities etc by the developers to make the system error free.  Unit Testing: Testing of individual software units i.e. for testing paths within a unit. Typically done by the programmer and not by testers, as it requires detailed knowledge of the internal program design and code. Functional and reliability testing in an Engineering environment. Producing tests for the behavior of components of a product to ensure their correct behavior prior to system integration. For ex, in searching module, searching of student on various criteria should be tested individually.  Integration Testing: This testing is used for testing path between units so that there will be no problem in the system by the developer.  System Testing: Testing conducted on a complete, integrated system to evaluate the system's compliance with its specified requirements. System testing falls within the scope of black box testing, and as such, should require no knowledge of the inner design of the code or logic. For ex, when the developer just focus on results of all modules with no navigation errors, display error etc and not focusing on coding or how it is implemented than System testing is been performed.
