Introduction:

This Online Examination and Result Publication System

(OERPUS) project will help the university/ Institution to evaluate thequestion has multiple options with one correct answer. This project

contains objective questions of different marks. Students have to

choose the correct answer for every question. The mark would be

evaluated automatically. This project helps the management to

conducting online examination, save the results and creates the

report of the student's results. So to do practice for the examination,

it will take the examination.

Earlier it was a very time consuming and tedious process where

both students as well as university used to perform all tasks

manually. It was cumbersome since these details were now

generated, managed and kept in computers. This software helps the

students and teachers to set the questions and take the exam through

this client/server application.

This application is coded in VB.Net. This Software project is very

much helpful to students, teacher and Institution. It stores the

information about Students, Report, Results, Students details etc. As

we know that this software project is coded in .Net programming

language, it is user friendly. That means this software is easy to

operate. Even a person having less knowledge of computer can easily

operate is, he will be guided throughout by the software to operate it.

This Software is a best effort of changing in paper work to electronic

work. Another advantage of this software is the database that is

designed very strongly; the current and previous information is stored

in this database and maintain the database very easily.

The backend of this application SQL SERVER is one of the leading

database management systems (DBMS) because it is the only Database that

meets the uncompromising requirements of todays most demanding

information systems. From complex decision support systems (DSS) to the

most rigorous online transaction processing (OLTP) application, even

application that require simultaneous DSS and OLTP access to the same

critical data, SQL Server leads the industry in both performance and

capability

SQL SERVER is a truly portable, distributed, and open DBMS that delivers

unmatched performance, continuous operation and support for every

database.

SQL SERVER RDBMS is high performance fault tolerant DBMS which is

specially designed for online transactions processing and for handling large

database application.

In a complete way, were expected to build a client/server based application

which accommodates all functionality of an Institution that deal with practice for

final examination.

Feasibility study:

The feasibility study of any system is mainly intended to study and

analyze the proposed system and to decide whether the system under

consideration will be viable or not after implementation. That is it determines the

usability of the project after deployment. To come to result a set of query is

answered keeping the efficiency of the software and its impact on the domain for

which it was developed. It main emphasis is on the following three questions

elucidated below as:

What are the users requirements and how does a candidate system meet

them?

What resources are available for the proposed systems? Is it worth solving the

problem?

What is the likely impact of the proposed system on the organization? I.e. how

does the proposed system fit within the organization?

Thus since the feasibility study may lead to commitment of large

resources, it becomes necessary that it should be conducted competently and

no fundamental errors of judgment are made. Different types of feasibility study

and the way we performed on our project Online Examination and Result

Publication System.


13/26


12

Technical Feasibility:

In technical feasibility, we study all technical issues regarding the

proposed system. It is mainly concerned with the specifications of the

equipments and the software, which successfully satisfies the end-users

requirement. The technical needs of the system may vary accordingly but

include:

The feasibility to produce outputs in a given time.

Response time under certain conditions.

Facility to communicate data.

Under this analysis process questions like (i) does the compatible platform

exist or can we procure it? (ii) Does the proposed equipment have the technical

capacity to hold the data required using the new system?

This analysis process requires more emphasis on system configuration given

more importance rather than the actual hardware specifications.

The configuration of the existing systems is:

Processor: Pentium III, 500 MHz (or above)

Memory: 128 MB (or above)

Secondary storage: 20 GB (or above)

For Software there are following alternatives:

Operating System: Window 2000,XP,NT, Windows 7

Development tools: VB.Net

Database: Microsoft SQL server 2005

Documentation tool: MS-Word


14/26


13

Economical Feasibility:

Are there sufficient benefits in creating the system to make the

acceptable? Or are the costs of not creating the system so great that it is

advisable to undertaken the project. This will include three major costs as

described below:

Cost of Hardware and Software.

Cost of Software to be acquired to build and run the product is a

one-time cost.

Buying a back and database is the major part of hardware and

Software cost.

Benefits in reduced cost, error and saving will be made by reduction of presentsystem expenses, time saving and increased accuracy.

Cost Avoidance:

Future cost reduction in form of reduction in the number of administrative

staff needed and manual records maintains in organization.

Rise in cost will be avoided.

Operational Feasibility (Social and other aspect):

The system will be used if it is developed well then be resistance from

users that undermine the possible application benefits.

Clients Supports:

Client and user support for present system is there, as the current procedure

used takes more time and effort than proposed system.

No major training and new skills are required as it is based on DBMS model.

It will help in the time saving and fast processing and dispersal of user request

and application.

New product will provide all the benefits of present system with better

performance such as improved information, better management and collection

of the reports.


15/26

User Support:

User involvement in the building of present system is sought to keep in

mind the user specific requirement and needs. User will have control over own

information. Important information such as Test result can be generated at theclick of a button.

Data Flow Diagram:

A data flow diagram is graphical tool used to describe and analyzemovement of data through a system. These are the central tool and thebasis from which the other components are developed. The transformationof data from input to output, through processed, may be described logicallyand independently of physical components associated with the system.These are known as the logical data flow diagrams. The physical data flowdiagrams show the actual implements and movement of data betweenpeople, departments and workstations. A full description of a systemactually consists of a set of data flow diagrams. Using two familiar notationsYourdon, Gane and Sarson notation develops the data flow diagrams. Eachcomponent in a DFD is labeled with a descriptive name. Process is further

identified with a number that will be used for identification purpose. Thedevelopment of DFDs is done in several levels. Each process in lower leveldiagrams can be broken down into a more detailed DFD in the next level.The lop-level diagram is often called context diagram. It consists a singleprocess bit, which plays vital role in studying the current system. Theprocess in the context level diagram is exploded into other process at thefirst level DFD.DFD SYMBOLS:

In the DFD, there are four symbols

1. A square defines a source(originator) or destination of system data

2. An arrow identifies data flow. It is the pipeline through which the

information flows

3. A circle or a bubble represents a process that transforms incoming data

flow into outgoing data flows.

4. An open rectangle is a data store, data at rest or a temporary repository

of data

Process that transforms data flow

PROJECT TESTING

1) COMPILATION TEST:

It was a good idea to do our stress testing early on, because it gave us

time to fix some of the unexpected deadlocks and stability problems

that only occurred when components were exposed to very high

transaction volumes.

2) EXECUTION TEST:

This program was successfully loaded and executed. Because of

good programming there was no execution error.

3) OUTPUT TEST:

The successful output screens are placed in the output screenssection.

Conclusion:The development of this project surely prompts many new areas of

investigation. This project has wide scope to implement it in any

University/Institution having multiple papers there. This project covers all

functionalities related to unit wise practice exam by setting separate sets for

each unit for the final exam. Hence it can be implemented any-where else after

minute organization level customization.

Moreover some parts of the project have remained uncompleted due to

some reasons. But it would have great to implement that provided wed enough

time.

Some of them are all those which are enumerated in the limitation section

like:

Randomly selected questions.

A module from where entities can communicate

Generating progress report for the students.
