This will help accounts department in maintaining the details related to the fees & basic details like their security deposits, conveyance and etc, it will also help management or we can say administration department in maintaining students basic details as well as keeping a check on fees details. This package is basically developed for the authorities of the school/institute to make their task easier or we can say this package automate their tasks like maintaining students personal details, marinating cash details, printing of receipts. This package helps the administrative & accounts department in maintaining the students personal & fees related details. The details of the system are as follows: It is basically a Database management package for the authorities of the school/institute like management, accounts & administrative department. All the details of the students & the daily work of various departments are managed by the package i.e. Personal details, Cash details, Fees status, printing of receipts etc. The package is by the name of School/institute Data Management Package. Package helps the various departments in maintaining & manipulating the data. School/institute data are divided into Personal information, Cash details, fee status & etc it helps in manipulating the divided parts of the data. Modules of the system: • • • •
Personal Information / Student details Fees Details Fees Status Report Generation
Personal Information / Student details: This module helps in managing the personal information of the students like their Name, Address, Phone no., Roll no & etc. The package helps in adding the personal records, editing the records, retrieval of records, report generation & etc.
Fees Details: This module helps in managing the fees details of the student like their tuition fees, security, late fees & etc. The basic purpose behind the development of this module is printing of receipts of the fees paid by the students. Fee Status: This module helps in managing the fees records of the students like how many have paid their fees & how many are yet to pay their fees & what is the receipt no. of the student who have paid their fees. Basically this module generates the list of all the students who have paid their fees & it also generates a list for those students who haven’t paid their fees.

NEED OF THE SYSTEM
The Package is developed to help the department maintaining the student details, earlier the records where maintained manually, with the help of this package the concerned departments will be able to improve the productivity, reduce the time, cost factors associated with the system. The automation of the system will help the organization in proper maintenance of the record, less manpower, less man-days, less cost, proper & accurate functioning. The basic need for the package was to automate the whole procedure of maintaining of student details, earlier it was all done manually. By developing this package lot of burden was removed from the department, which was maintaining students details. It improved the efficiency, reduced the cost, and reduced the time need to do the work manually. With the help of this package the past details of the students can assessed and reports can be generated on this details. In brief we can say this system was required to automate the processing of students details, which was done manually before the development of the package. Earlier all the information / data pertaining to the students was maintained manually or we can say it was on paper, hence it created a problem for the organization/ school, how to manage it properly. With the help of this system the organization/school is able to maintain the data properly & accurately. Why System was build…? • • • • • •
Earlier, data pertaining to students was maintained manually. Manual system was not efficient. Cost of maintaining data manually was bigger or huge. Large manpower was required. The procedure was error prone, it was not accurate. Manual system was not suited for electronic exchange of data.
Solution…? The solution for all this problem was to automate the system, automation of the students data maintenance would reduce the manpower, man days will result in accurate data & above all increase the efficiency of the concerned department.

FEASIBILITY STUDY
Feasibility is the test of the system it helps in deciding whether it is viable to go through the project or not. Feasibility study studies the system & tells whether to develop the system or not. In lay mans terms it can be described as the test of the system & if the system passes in the test then it is viable to develop the project otherwise not or we can say feasibility study check’s whether project is feasible or not. Feasibility has four solid dimensions: 1. 2. 3. 4.
Technology Finance Time Resources
The feasibility of the system “ SCHOOL Data Management System ” is viewed with the help of these four dimensions. Technology: This system uses one of the simplest technologies in use, for the development purpose it uses simple to use & easily available technology. This system is based on windows like interface, which is very easy to use. The package is been developed for the department, which is not very familiar with software hence technology used, must be easily understandable, because of which windows like interface has been chosen. The technology used in this project is VB i.e. Visual Basics 6.0, M S Access & DAO controls. Visual Basic helps in providing windows like environment. This system uses menu-based approach in which every thing is given with the help of menus. Finance: This dimension measures the system in respect to money or we can say funds. This dimension checks whether its viable to spend the required amount on the system or it will be a waste. There is no problem of finance in this project because it uses simple technology, which is very easy to install. This system is been developed for a standalone computer hence for this system hardware requirement is very low. For this system to be developed & installed properly we require very easily available technologies & very basic hardware and all these requirements doesn’t cost much. Time:
This particular dimension measures the systems worth in respect to time, which is one of the most important factors to be considered. In this project time factor is very important this system is scheduled to be installed in one months time. This system is not very big & hence can be completed within the time period it requires approx. 30 man-days of work. Time is a crucial factor to be considered & we can say this system can be developed within the required time period.
8
Resources: This dimension takes into count the recourses required to develop the system. For this particular system the resources required are quite nominal which can be fulfilled, the resources required for this system are basic hardware, an operating which is compatible with VB.
With the help of all these dimension we can measure the feasibility of the system & can decide whether to go forward with the project or not. By take in count the dimension & their role in this particular system we can say this system is feasible from all these dimension point of view & it is viable to go through the project.

SCOPE OF THE SYSTEM
Scope of the system measures the scope of the project, which is going to be developed. Answering following aspects can answer the project scope: 1. 2. 3. 4.
Context Information objective Function & Performance Interfaces
The system “SCHOOL data management system” is a data management of students. All the details of the students are managed with the help of this package i.e. their Personal information, fees information & their report generation, with the help of this package the organization can maintain & manipulate students data. This package has the provision for adding new records, editing old records, viewing the database, searching facility, report generation, help i.e. how to use the package & etc. Scope of the system can be measured with the help of the dimensions. Context: This project is related to management of students data and the daily activities of the authorities with the help of this package the user of this package, which is the department i.e. administrative will be able to maintain the data through the computer which will help in increasing he efficiency, accuracy of the department as well as help in electronic inter change of the data. Administrative department can use this package to check for the details of the students, whether they have paid their fees amount or whether it is due to them, through which receipt no. it was paid they can study the past records analyze the trends. Information objective: Basically this is related to the Inputs & Outputs to the system. In other way we can say it is related to the inputs required by the system & outputs generated by the system. This package is basically data management package, in which the inputs given by the user is itself the output of system it performs few calculation like the total cash received from the students. We can say it is data management package, it provides the user with front end which is very easy to use. 1. Inputs: The input to the system is username & password for the system security, their Personal details like Name, Address, Phone number, admission details, roll no for data management, their fees details like admission fees, tuition, computer fee & etc . 2. Outputs: The output for this system is the maintained records, personal details, fees details, fee status & report generated. The outputs of the system are the records that were added in the database as well as the reports that are generated with the help of he data in the database.
10
Function & Performance: This dimension measures the scope of the system with the help of functions & performance of the system. The basic function performed by the system is of data management & report generation. The system performs various functions like: 1. Security:
The first function of the system is to provide security from unauthorized access to the data, which is provided with the help of user name & password at the beginning of the package. This system is been developed for a single user hence no rights are employed or we can say administrator is only the user. 2. Data maintenance: The most important function of the system is to maintain student data, the data is maintained with the help of different menus like adding, editing, viewing, searching & etc. There are different kinds of data in the system like personal information, fees information & cash details with the help of the front end data is managed. 3. Report generation: The last function of the system is to generate reports of the data like student details report, cash report, fee status report & etc. With the help of this report the data can be electronically exchanged as well as the reviewing of policies can be done with the help of reports. These are some of the basic function performed by the system “Student Data Management”. Interfaces:
Interfaces are the link between the user and the system, basically we can say interfaces are the objects through which user of the system interacts with the system. This system has different interfaces through which user interacts with the system they are: 1. Login interface: This is the first interface in which user is required to enter the username & password if the password is correct then access is granted otherwise not. User has got three attempts to enter the correct password; if he is not able to enter the correct password in three attempts then the system is exited. 2. Data maintenance: This is the most important interface in the system in which the user interacts with the system to store the data or to retrieve the data from the database, this interface has got many sub parts like addition of records, editing of records, searching of records & etc. 3. Reports: This interface is the output for the system in which the user receives the results or output, which is required in the form of reports like cash details, student details & fee status.
11
OBJECTIVE The following are the main management ":
objectives

OPERATING ENVIORNMENT
The system is developed in Visual Basics 6.0 / M S Access and run under windows 95/98 & upper versions. Visual Basics: Visual basics is event driven programming language, which is used to develop front end for the application. This is called event driven because every action of the user is an event & the application is driven with the help of these events, which are programmed with the help of Visual basics. In Visual basics there are forms, Controls, reports & many more things to provide the user with overwhelming experience of user friendliness. Visual basics is a programming language for windows environment & provides the user with windows like interface. M.S. Access: Access is a Relational Database Management System (RDBMS) that you can use to store and manipulate large amounts of information. Because its tools are user-friendly and because it is a powerful development environment, Access is equally appropriate for novices and MIS professionals. Beginners can use Access to:
1. Store and manage various types of inventories. 2. Log information such as auto repairs for cars, doctor visits, etc. 3. Create contact management databases that can track contacts, but phone calls, meetings, and any other interactions with contacts. Developers can use Access to: 1. Create applications that manage survey results. 2. Manage front ends for enterprise-wide database such as SQL server. 3. Establish help-desk applications. Access is an object-oriented program; that is, everything in Access is an object, including the application itself. Each object has properties that define how it looks and performs. The uses of Access are limited only by the needs of an organization and the imagination of the user or developer.

SYSTEM REQUIREMENTS SPECIFICATION
The function and performance allocated to software as part of system engineering are refined by establishing a complete information description, a detailed functional and behavioral description, an indication of performance requirements and design constraints, appropriate validation criteria, and other data pertinent to requirements. The outlines of system requirement specification are: Introduction: This System Requirement Specifications Document forms the basis for the design and development of the ”Student data management”. The purpose of this document is to define all the processes involved in the function of Student data management. The requirements of the software relating to the functionality, interfaces, logical database requirements and various other aspects of the software are also explicitly defined. The SRS document will also act as the basis for understanding between the end-user and the designer/developer. Information Description: The development of this system assists in the maintenance of the information and to fulfill the complete software requirements of the package. Functional Description: A processing narrative is provided for each function, design constraints are stated and justified, performance characteristics are stated and diagram is included. Validation and Criteria: For successful implementation of the system we should define the performance bounds, and expected software response. At the time of creating new entry, system performs different types of validations like user can not overwrite the existing information, it asks the user, this information already exist and also many feature.

DFD’S
DFD:
It stands for Data flow diagram it is a diagrammatic representation of the data objects of the system. Basically DFD is a way to show the how the data is processed in the system, it shows how data moves at different stages in the system. DFD is a graphical representation that depicts information flow & the transformations that are applied as data moves from input to output. It is also used to represent a system or software at any level of abstraction it can be partitioned into levels that represent increasing information flow & functional details. Data Flow Diagram serves two purposes: 1. To provide annunciation of how data are transformed as they move through the system. 2. To depict the functions that transforms the data flow. DFDs are a excellent mechanism for communicating with the customer during requirement analysis and are widely used for the representation of external and toplevel internal design specification. In the latter situations, DFDs are quite valuable for subsystem, files and data links. The DFD methodology is quite effective, especially when the required design is unclear. In the process, many levels of DFDs are created depending upon the level of details needed. The Level 0 DFD is also called Context Level DFD. It depicts the overview of the entire system. The major external entities, a single process and the output stores constitute the level-0 DFD. Though this diagram does not depict the system in detail, it represents the overall inputs, process and output of the entire system at a very high level. The Level 0 DFD is now expended into a level 1 model. It should be noted that information flow continuity is maintained between level 0 and level 1. The process represents at DFD level 1 further refined into lower levels. This further refinement is continued until an easily implement able program component is reached.

ER-DIAGRAM
Entity – Relationship Diagram: Depicts relationships between data objects. The object-relationship pair can be represented graphically using the Entity-Relationship Diagram. A set of primary components is identified for the ERD: data objects, attributes, relationships, and various type indicators. The primary purpose of the ERD is to represent data objects and their relationships. Data Objects, Attributes, and Relationships The data model consists of three interrelated pieces of information: the data object, the attributes that describe the data object, and the relationships that connect data objects to one other. Data Objects: A data object is a representation of almost any composite information that must be understood by software. By composite information, we mean something that has a number of different properties or attributes. A data object encapsulates data only there is no reference within a data object to operations that act on the data. The data object description incorporates the data object and all of its attributes. Data objects are related to one another. Attributes:
Attributes define the properties of a data object and take on one of three different characteristics. They can be used to name an instance of the data object, describe the instance, or make reference to another instance in another table. The set of attribute that is appropriate for a given data object is determined through an understanding of the problem context. One or more of the attributes must be defined, as an identifier that is identifier attribute becomes a “Key” when we want to find an instance of the data object. Relationships: Data object are connected to one another in a variety of different ways. We can define a set of object-relationships pairs that define the relevant relationships. Object-relationship pairs are bi-directional. Different data objects and their attributes are described in data dictionary and their relationships between these data objects are given in ER diagram of next section. Cardinality and Modality Cardinality: The data model must be capable of representing the number of occurrences of objects in a given relationship. The cardinality of an object-relationship pair are: 1. One-to-one (1:1): An occurrence of object ‘A’ can relate to one and only one occurrence of object ‘B’ and an occurrence of ‘B’ can relate to only one occurrence of ‘A’.
21
2. One-to-many (1:N): One occurrence of object ‘A’ can relate to one or many occurrences of object ‘B’ but an occurrence of ‘B’ can relate to only one occurrence of ‘A’. 3. Many-to-many (M: N): An occurrence of object ‘A’ can relate to one or more occurrences of ‘B’, while an occurrence of ‘B’ can relate to or more occurrences of ‘A’.
Cardinality defines “the maximum number of object relationships that can participate in a relationship”. Modality: The modality of a relationship is zero if there is no explicit need for the relationship to occur or the relationship is optional. The modality is 1 if an occurrence of the relationship is mandatory.

IMPLEMENTATION STRATEGIES
A crucial phase in the system life cycle of the successful implementation of the new system design. Implementation simply means conveying a new system design into operation. This involves creating computer-compatible files, training the operating staff and installing hardware, terminals and telecommunication networks before the system is up and running. A critical factor in conversion is not disrupting the functioning of the organization. In system implementation, user training is crucial for minimizing resistance to change and giving the new system a chance to prove its worth. Training aids, such as user friendly, manuals, a data dictionary, job performance aids that communicate information about the new system and “help” screens provide the user with a good start on the new system.
There are three types of implementation: 1. Implementation of a computer system to replace a manual system: The problems encounter are converting files, training users, creating accurate files and verifying printouts for integrity. 2. Implementing of a new computer system to replace an existing one: This is usually a difficult conversion. If not properly planned there can be many problems. Some large computer system has taken as long as a year to convert. 3. Implementation of a modified application to replace an existing one using the same computer: This type of conversion is relatively easy to handle, provided there are no major changes in the files. Conversion means changing from one system to another. The objective is to put the tested system into operation while holding costs, risks, and personnel irritation to a minimum. It involves – Creating computer compatible files Training the operating staff

Installing terminals and hardware. A critical aspect of conversion is not disrupting the function of the organization. Several procedures and documents are unique to the conversion phase. Conversion begins with a review of the project plant, the system test documentation, and the implementation plan. The parties involved are the user, the project team, programmers, and operators
The conversion portion of the implementation plan is finalized and approved.

Conversion is completed. Plans for the post-implementation review are prepared. Following the review, the new system is officially operational. File conversion involves capturing data and creating a computer file from existing files. Copying the “old” files intact for the new system is the prime concern during conversion. The programs that copy the files should produce identical files to test programs on both systems. At the outset, a decision is made to determine which files need copying. Personnel files must be kept of course, but an account receivable file with many activities might not need copy in. Instead, new customer accounts might be put on the new system, while running out the old accounts on the old system. Once it is determined that a particular file should be transferred, the next step is to specify the data to be converted, current file, year-end files, and son on. Then files to be copied must be identified by name, the programmer who will do the copying, and the methods by which the accuracy of the copying will be verified. A filecomparison program is best used for this purpose.

TESTING & TEST RESULTS
TOPICS COVERED I. TESTING II. USER MANUAL

TESTING
Testing: Testing is the process of executing the programs with the intention of finding out errors. During testing, the program to be tested is executed with a set of test cases and the output of the programs for the test case is evaluated to determine if the program is performing as it is expected to be. As the software is created and added to the developing system, testing is performed to ensure that it is working correctly and efficiently. Testing is generally focused on two areas, internal efficiency and external effectiveness. The goal of external effectiveness testing is to verify that the software is functioning according to system design, and that it is performing all the required functions. The goal of internal testing is to make sure that the computer code is efficient, standardized, and well documented. Testing can be a labor-intensive process due to its iterative nature.
Test Plan: We divided the testing procedure into these levels:
Unit Testing. Integration Testing. Validation Testing. System Testing.
These different levels of testing attempt to detect different types of faults. The relations of faults introduced in different levels of testing are as shown below

Unit Testing Levels of Testing
71
Unit Testing: The first level of testing is called unit testing. In this, different modules are tested against the specifications produced during design for the modules. Unit testing is essential for verification of the code produced during the coding phase, and the goal is set to test the internal logic of the modules. Integration Testing: The next level of testing is often called the integration testing. In this many tested modules are combined into subsystems, which are then tested. The goal here is to see if the modules can be integrated properly, the emphasis being on testing interfaces between modules. This testing activity can be considered as testing design and hence the emphasis on testing interactions.
Validation Testing: During validation testing, the system is used experimentally to ensure that the software does not fail, i.e. will run according to its specifications and in the way users accepts, special test data input for processing, and the results examined. A limited number of users may be allowed to use the system so analysts can see whether they try to use it in unforeseen ways. System validation checks the quality of the software in both simulated and live environments. First the software goes through a phase in which error and failures based on simulated user requirements are verified and studied, called alpha testing. The modified software is then subjected to phase two in the actual user’s site or a live environment, called beta testing. System Testing: A series of different tests whose function is to verify that all system elements have been properly integrated and perform allocated functions.
Testing of “Student Data Management ”: In case of Student data management package, I performed unit testing to each individual function to see that whether they are working properly or not. We examined each loop, which occurred in the functions for every possible value. Integration testing was also being performed by combining the different modules and the results were examined. Some steps are taken for testing: 1. 2. 3. 4. 5.
Proper validation is done or not. Exceptions are handled or not. Correct menus open or not. Records are properly updated & saved or not. Is system able to detect Intruder?

Samples Of Unit Testing: Few samples of unit testing are explained with the help of screen outputs. Unit testing is basically testing the modules with the dummy data.
If Admission no is not in the database message will be prompted. No record found.
If search button is pressed before entering the name it will ask for the field.

LIMITATION OF THE SYSTEM
Limitations of the system and future development areas:
Limitation of any system is difference between the required system & the developed system: -
1. It is developed for only stand-alone PC. 2. This system is quite easy to use this is not its limitation but its restrictive features are its limitation. 3. The back end used in the system is M S Access, which is not an RDBMS. 4. The system does not support multiple users. 5. There are few things, which should be kept in mind while using the system.
