is
designed
for
Educational
Institutes like
Schools, Colleges, and Private Institutes to conduct logic tests of their students on a regular basis. The system handles all the operations and generates reports as soon as the test is completed which saves the precious time of faculties spent on reviewing answer sheets. The existing system is weak when it comes to surprise test organizations whereas this system can make it possible very easily.

Chapter 2 Project Management
2. 2.1
PROJECT MANAGEMENT PROJECT DEVELOPMENT APPROACH Software Process Model To solve actual problems in an industry, software developer or
a team of developers must incorporate a development strategy that encompasses the process, methods and tools layers and generic phases. This strategy is often referred to as process model or a software developing paradigm. A process model for software developing is chosen based on the nature of project and application, the methods and tools to be used, and the controls and deliverables that are required. All software development can be characterized as a problem solving loop in which four distinct stages are encountered: Status quo, Problem definition, technical development and solution integration. Regardless of the process model that is chosen for a software project all of the stages coexist simultaneously at some level of detail. Our Project Follows the Waterfall Model THE WATERFALL MODEL The steps of the typical Waterfall Model are: 1. Requirement Definition 2. System & Software Design 3. Implementation 4. Integration & System Testing 5. Operation and Maintenance

Chapter 4 System Analysis
4. 4.1
SYSTEM ANALYSIS STUDY & WEAKNESSES OF CURRENT SYSTEM. Current System The Current system of examinations is highly complicated and expensive. Whenever exams are to be conducted there are various tasks that have to be done again and again. Setting question paper Checking for errors Printing question papers Scheduling Exams Conducting Exams Checking Answer Papers Preparing Result Charts Solving Question Papers Weaknesses in Current System The current system is as mentioned earlier very complicated and expensive as compared to the new system. It also wastes the precious time of the faculties which can then be used in solving student queries and helping them improvise. Taking surprise tests of students is also not feasible in the current system as planning for the exam and checking answer papers takes a lot of time and thus cannot be completed on schedule. It also has no measures to prevent students from copying the answers rather than printing different sets of question papers which in turn can result expensive.
10
Chapter-4
System Analysis
As Faculties are humans and so prone to errors, there can be mistakes in checking answer papers, calculating marks and the result charts prepared may also have these errors. Only preventive measures are taking a double check to ensure these errors don’t happen which would again require extra time and may also result in a mentally tired faculty. After the exams have been conducted the faculty has to provide solutions to the questions asked in exam. It would mean extra time and extra work for the faculty and also result in extra expenses of stationary. Thus, the current system is in every way ineffective for conducting examinations in these days when time is more costly than anything and they also pose a threat to the environment when we are amidst a global crisis and in the need of a Green Revolution.
4.2
REQUIREMENTS OF NEW SYSTEM. 4.2.1 User Requirements. The User requirements for the new system are to make the system fast, flexible, less prone to errors and reduce expenses and save time. o Time can be saved in scheduling the exams if it were available to make question banks to store questions for different subjects in advance and can be used as per required. o
A system that can automate the checking of answers which are pre-stored so that results can be generated as soon as the student gives the exam.
o
A facility that can generate result charts as per required without manual interference for providing how a task is to be done instead only asking what is to be done.
o
The system should have Student and Faculty records on hand which can be used as per required only by authorized personnel.
11
Chapter-4
System Analysis
o
The New system should be more secure in managing user records and reliable enough to be used in any condition.
o
Finally, it should prove cost effective as compared to the current system.
4.3
Feasibility Study A key part of the preliminary investigation that reviews anticipated costs and benefits and recommends a course of action based on operational, technical, economic, and time factors. The purpose of the study is to determine if the systems request should proceed further. 4.3.1 Does the New System Contribute to the Overall Objectives of the Organization? The new system would contribute to the overall objectives to of the organization. It would provide a quick, error free and cost effective solution to the current process. It would provide a solution to many issues in the current system. As the new system is flexible and scalable it can also be upgraded and extended to meet other complex requirements which may be raised in the future. However it is up to the organization to upgrade or extend it. 4.3.2 Can the New System be Implemented Using Current Technology? The organization has a computer laboratory which has about 50 machines connected by Internet Lan and managed by a server. It would be very easy to set up the system in the current environment as the application is web based it does not require to be installed on every machine. The database and IIS are set up on the server and the .Net Framework installed on every machine, the system can be started as quick as required by the management.

System Analysis
Features of the New System. The new system has been designed as per the user requirements so as to fulfill almost all them. Quick Scheduling Exams can be created very quickly as compared to the existing system as it allows the use of previously entered questions to be used again. It saves time required to get the question papers printed and distributed before the students are allowed to appear for the examination. Questions entered once can be accessed by students as soon as they login to their account. Immediate Results and Solutions One of the most important draw backs of the current system is that the faculties are required to check the answer papers which is again a lengthy process and prone to errors. The new system will generate the result as soon as the test is finished by the user and will also store it in the database for further usage. The solution is also available as soon as the questions are inserted in the database. Easy to Store and Retrieve Information The new system makes it easy to store and retrieve information as required and does not involve storing information in separate sheets or papers. It thus saves data management problems faced in the current system as it has a Database Management System of it own which allows 33 reports to be generated when needed. Cost Effective One of the main reasons of the new system is its cost effectiveness. It saves the amount spend on stationary as well as overall cost of conducting an examination which also involves paying supervisors, paper checkers, question paper printers etc.

System Design
DATA FLOW DIAGRAM (DFD) The DFD (also known as bubble chart) is a simple graphical formalism that can be used to represent a system in terms of the input data into the system, various processes carried on these data, and the output data generated by the system. The main reason why the DFD technique is so popular is because the fact that the DFD is a very simple formalism - it is simple to understand and use. A DFD model uses a very limited number of primitive symbols to represent the functions performed by a system and the data flow among the functions. Starting with a set of high-level functions that a system performs, a DFD model hierarchy represents various sub-functions.

5.3.2 Entity Relationship Diagram An Entity-relationship model is an abstract conceptual representation of structured data. Entity relationship modeling is a relational schema database medeling method, used in Software Project Management to produce a type of conceptual data model (or semantic data model) of a system, often a relational database, and its requirements in top-down fashion.

LIMITATIONS AND FUTURE ENHANCEMENTS
7.1
LIMITATIONS The new system has been designed to meet almost all of the user requirements but it too has certain limitations some of which can be enhanced in the future enhancements or updates. 7.1.1 Supports only Multiple choice and no Theory The existing system supports only multiple choice questions and these can be used only for the logic testing of the student whereas paper based tests can provide a overall result of the users knowledge for that topic. This will do injustice to users who are sometimes aware of answers but not sure completely. It supports only two values True and False. If the selected answer is true the user gets marks, If not loses. 7.1.2 No Image Support The existing system has no image support at present and so images and diagrams cannot be included in the exam which would make it very difficult to ask certain questions in certain subjects. Providing diagrams externally is at present the only feasible choice available. 7.1.3 No Back Option Available The existing system also lacks a back option which would take a user to a previously answered question in case he wants to check or change his choice. This makes it very difficult and quite stressful for the user to choose an option which is totally contrary to the theory tests in which the user can review and change his answers. This has been an important point in the proposed enhancements in the system.
Chapter-7
Limitations and Future Enhancements
7.1.4 Exam Time Cannot be Modified The existing system allows the exam time to be set only once at the time of system set up which cannot be changed as per desired and all the exams will be conducted for the preset time only. If the user wants to increase or decrease the time for exams the system will have to be set up again. This is also one of the proposed enhancements. 7.1.5 No of Questions in an Exam cannot be changed. The system will have a preset no of questions that can be attempted in an exam by the user which cannot be changes in the existing system. If a user wants that an exam has to have more or less questions than the system has to be ser up again which is again not feasible. The proposed system enhancements will have a field in the faculty module where the faculty can set no questions and time allowed for a selected subject. 7.1.6 No Facility for the Disabled The existing system has no options available by which a physically disabled user can use the system. If the user is blind or deaf the system has no sound response pr Braille response facility. This makes it very difficult to set this system as a standard for all examination procedures as it does not support all time of users that a standard system is supposed to.
7.2 FUTURE ENHANCEMENTS. Enhancements are the perquisite for development of a system. Every existing system has proposed enhancements which make it better and easier to use and more secure. The enhancements that have been proposed for this system are listed here.
Chapter-7
Limitations and Future Enhancements
7.2.1 Including Image Support. The existing system has no image support due to which the images cannot be used. It will be one of the priorities in the proposed enhancements to enable Image Support in the system. 7.2.2 Including Back Option The new system will have a back option which will enable the users to go back to previously answered questions and change them if needed. It will enable the user a hassle free exam so that the user can properly utilize the total time allotted for the test. 7.2.3 Facility to Set Exam Time. The new system will allow the faculty to set the exam time for a particular subject. It will increase the efficiency of the system greatly as it will enable each subject to be tested for a different duration as desired and required. 7.2.4 Facility to Set No of Questions in Exam The new system will allow the faculty to set no of questions that can be asked in a subject. It will improve the flexibility of the exams by allowing the faculty to change the no of questions that can be asked in a subject. 7.2.5 Flags The new system will allow the users to set flags for an answered question. Flags like Passed. Doubtful, Answered etc will help a user to return to those questions to review them and change them accordingly.
Chapter 8 Conclusion
9 9.1
CONCLUSION CONCLUSION The development of software includes so many people like user system developer, user of system and the management, It is important to identify the system requirements by properly collecting required data to interact with supplier and customer of the system. Proper design builds upon this foundation to give a blue print, which is actually implemented by the developers. On realizing the importance of systematic documentation all the processes are implemented using a software engineering approach. Working in a live environment enables one to appreciate the intricacies involved in the System Development Life Cycle (SDLC). We have gained a lot of practical knowledge from this project, which we think, shall make us stand in a good state in the future.
