ABSTRACT

This document is meant for describing all the features and procedures that

were followed while developing the system. This document specially mentions

the details of the project how it was developed, the primary requirement, as well

as various features and functionalities of the project and the procedures followed

in achieving these objectives. Online Examination System forms the lifeline of the

Educational Institutes to the functioning of the Examination. It is very essential for

an Institute to handle the Examinations and their results. It is very useful for anInstitute to test its students continuously for their mutual development. This

system is helpful for conducting (M.C) Multiple Choice Examinations which can be

conducted regularly as well as for surprise tests and provides immediate results

saving the precious time of faculties to check the papers and prepare mark

sheets.

The IT initiatives have encouraged various Organizations to develop

systems to facilitate their day to day operations. The Online Examination System

will include various Engineering Courses and subjects for conducting

examinations. This system helps in conducting examinations quickly ancan thus

help in saving time and the operations will be carried out efficiently. With the

IntroductionOnline Examination System is being launched because a need for a

destination that is beneficial for both institutes and students. With this site,

institutes can register and host online exams. Students can give exams and view

their results. This site is an attempt to remove the existing flaws in the manual

system of conducting exams.

Purpose

Online Examination System fulfills the requirements of the institutes to

conduct the exams online. They do not have to go to any software developer to

make a separate site for being able to conduct exams online. They just have to

register on the site and enter the exam details and the lists of the students which

can appear in the exam. Students can give exam without the need of going to any

physical destination. They can view the result at the same time. Thus the purpose

of the site is to provide a system that saves the efforts and time of both the

institutes and the students.

What is Online Examination System all about?

Online Examination System is a web application that establishes a network

between the institutes and the students. Institutes enter on the site the questions

they want in the exam. These questions are displayed as a test to the eligible

students. The answers enter by the students are then evaluated and their score is

calculated and saved. This score then can be accessed by the institutes to

determine the passes students or to evaluate their performance.

1.2 SYSTEM OVERVIEW

Online Examination System is built on Asp.Net, Microsoft VS-2010 and MS-

ACCESS 2007.The Web application is built to server in the following areas.

To make the examination process in the institutes fast, reliable, and errorfree.

Hosting on the Intranet can provide a secured Examination channel for anyinstitute.

Registration of users can be used to generate revenue and thus can beprofited form the system.

Real time report generation gives quick results to given exams. Entrance examinations can also be conducted. The database is self explanatory as the code.

1.3 OBJECTIVE

Create a Web application to be used in place of old paper based userexamination process.

Use ASP.NET and SQL Server technology to create strong and secureddatabase connectivity.

Incorporate the server software within the code. Runtime package and deployment instructions are given.

1.4 SCOPE

Online Examination System is designed for Engineering 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.

2. Project Management2.1. PROJECT DEVELOPMENT APPROACH

The establishment and use of sound engineering principles in order to

obtain economically developed software that is reliable and works efficiently on

real machines is called softwareengineering.

Software engineering is the discipline whose aim is:

1. Production of quality software

2. Software that is delivered on time

3. Cost within the budget

4. Satisfies all requirements.

Software process is the way in which we produce the software. Apart from

hiring smart, knowledgeable engineers and buying the latest development tools,

effective software development process is also needed, so that engineers cansystematically use the best technical and managerial practices to successfully

complete their projects.

A software life cycle is the series of identifiable stages that a software

product undergoes during its lifetime .A software lifecycle model is a descriptive

and diagrammatic representation of the software life cycle .A life cycle model

represents all the activities required to make a software product transit through

its lifecycle phases .It also captures the order in which these activities are to be

taken .


10/44


11/44

Requirement analysis and specification: The goal of this phase is tounderstand the exact requirements of the customer and to document them

properly.(SRS)

Design: The goal of this phase is to transform the requirement specificationinto a structure that is suitable for implementation in some programming

language.

Implementation and unit testing: During this phase the design isimplemented. Initially small modules are tested in isolation from rest of the

software product.

Integration and system testing: In this all the modules are integrated andthen tested altogether.

Operation and maintenance.Release of software inaugurates the operation and life cycle phase of the

operation. The phases always occur in this order and do not overlap.

4. System Analysis

4.1. STUDY & WEAKNESSES OF CURRENT

SYSTEM.

4.1.1. 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


14/44

4.1.2.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.

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 dont 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.


15/44

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.

Time can be saved in scheduling the exams if it were available to makequestion banks to store questions for different subjects in advance and can

be used as per required.

A system that can automate the checking of answers which are pre-storedso that results can be generated as soon as the student gives the exam.

A facility that can generate result charts as per required without manualinterference for providing how a task is to be done instead only asking what

is to be done.

The system should have Student and Faculty records on hand which can beused as per required only by authorized personnel.

The New system should be more secure in managing user records andreliable enough to be used in any condition.

Finally, it should prove cost effective as compared to the current system.


16/44

4.3 FEASIBILITY STUDY

A key part of the preliminary investigation that reviews anticipated costsand 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 doesnot 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.


17/44

4.4. Features of the New System

The new system has been designed as per the user requirements so as to

fulfill almost all them.

Quick SchedulingExams 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 SolutionsOne 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 InformationThe 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 EffectiveOne 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.

5. System Design

5.1 DATA FLOW DIAGRAM (DFD)

A DFD also known as bubble chart, has the purpose of clarifying system

requirements and identifying major transformations. It shows the flow of data

through a system. It is a graphical tool because it presents a picture. The DFD

may be partitioned into levels that represent increasing information flow and

functional detail. Four simple notations are used to complete a DFD. These

notations are given below:-

DATA FLOW:- The data flow is used to describe the movement ofinformation from one part of the system to another part. Flows represent

data in motion. It is a pipe line through which information flows. Data flow

is represented by an arrow.

Data flow

PROCESS:- A circle or bubble represents a process that transforms incomingdata to outgoing data. Process shows a part of the system that transform

inputs to outputs.

EXTERNAL ENTITY:- A square defines a source or destination of system data.External entities represent any entity that supplies or receive informationfrom the system but is not a part of the system.

5.3.2 Entity Relationship Diagram


27/44

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.

7. Testing

7.1.TESTING

Software testing is the process of executing a program with intension of

finding errors in the code. It is a process of evolution of system or its parts by

manual or automatic means to verify that it is satisfying specified or requirements

or not.Generally, no system is perfect due to communication problems between

user and developer, time constraints, or conceptual mistakes by developer.To

purpose of system testing is to check and find out these errors or faults as early as

possible so losses due to it can be saved. Testing is the fundamental process of

software success.

Testing is not a distinct phase in system development life cycle but should

be applicable throughout all phases i.e. design development and maintenance

phase.Testing is used to show incorrectness and considered to success when an

error isdetected.

7.2.OBJECTIVES OF SOFTWARE TESTING

The software testing is usually performed for the following objectives:-

Software quality improvement:-The computer and the software are mainly used

for complex and critical applications and a bug or fault in software causes severe

losses. So a great consideration is required for checking for quality of software.


43/44

7.2.1.VERIFICATION AND VALIDATION:-

Verification means to test that we are building the product in right way .i.e.

we are using the correct procedure for the development of software so that it can

meet the user requirements.

Validation means to check whether we are building the right product or

not.

7.2.2. SOFTWARE RELIABILTY ESTIMATION:-

The objective is to discover the residual designing errors before delivery to

the customer. The failure data during process are taken down in order to estimate

the software reliability.

7.2.3.PRINCIPLES OF SOFTWARE TESTING

Software testing is an extremely creative and challenging task. Some important

principles of software testing are as given:-

All tests should be traceable to customer requirements.

Testing time and resources should be limited i.e. avoid redundanttesting.

It is impossible to test everything. Use effective resources to test. Test should be planned long before testing begins i.e. after requirement

phase.

Test for invalid and unexpected input conditions as well as validconditions.

Testing should begin in in the small and progress towards testing inthe large.

For the most effective testing should be conducted by an independentparty.

Keep software static (without change mean while) during test.


44/44

7.3. STRATEGY FOR SOFTWARE TESTING

Different levels of testing are used in the test process; each level of testing

aims to test different aspects of the system.

The first level is unit testing. In this testing, individual components are

tested to ensure that they operate correctly. It focuses on verification efforts.

The second level is integration testing. It is a systematic technique for

constructing the program structure. In this testing, many tested modules are

combined into the subsystem which are then tested. The good here is to see if the

modules can be integrated properly.

Third level is integration testing. System testing is actually a series of

different tests whose primary purpose is to fully exercise computer based system.

These tests fall outside scope of software process and are not conducted solely by

software engineer.
