ACKNOWLEDGEMENT

History of all great works is to witness that no great work was ever done

without either the active or passive support of a person's surroundings and one's

close quarters. Thus it is not hard to conclude how active assistance from seniors

could positively impact the execution of a term paper. I am highly thankful to

our learned facultyJaspreet Kaur Sahiwal

for heractive guidance throughout the teaching period. Thats why I am able to

give progress report of my term paperONLINE EXAMINATION

Last but not the least I would also want to extend my appreciation to those who

could not be mentioned here but have well played their role to inspire me behind the

curtain.

ONLINE EXAMINATION

PURPOSE:This Application provides facility to conduct online Examination when implemented

through applets . It saves time as it allows number of students to give the exam at a

time and displays the results as the test gets over, so no need to wait for the result. It isautomatically generated by the machine. Administrator has a privilege to create, modify

and delete the test papers and its particular questions. User can login and give the test

with his name and can see the results as well.

TECHNOLOGIES USED:This project is a java application that is developed in Net Beans.

HARDWARE INTERFACE:An operating system with java installed in itProcessor : Pentium IV 2.0 and above.

RAM : 256 MB

Disk space : not much taken by system

SOFTWARE INTERFACE:Java installed system, NetBeans, Windows XP/2000/Vista

CONSTRAINTS:1. User interface is only in English i.e. no other language option is available.2. User can login only with any name but password is same for all i.e. no guest facility

is available.

FEASIBILITY STUDYWhat are the users demonstrable needs?

User needs a Java enabled system, which will remove all the above-mentioned problems

that, the user is facing. The user wants a program, which will reduce the bulk of paperwork,

provide ease of work, flexibility, fast record finding, modifying, adding, removing and

generating the reports.

How can the problem be redefined?

I proposed our perception of the system, in accordance with the problems of existing

system by making a full layout of the system on paper. We tallied the problems and needs

by existing system and requirements. In feasibility study phase we had undergone through

various steps, which are described as under:

How feasible is the system proposed? This was analyzed by comparing the following

factors with both the existing system and proposed system.

1. CostThe cost required in the proposed system is comparatively less to the existingsystem.

2. EffortCompared to the existing system the proposed system will provide a better working

environment in which their will be ease of work and the effort required will be

comparatively less than the existing system.

3. TimeAlso the time required generating a report or for doing any other work will becomparatively very less than in the existing system. Record finding and updating will take

less time than the existing system.

4. LaborIn the existing system the number of staff required for completing the work is more while

the new system will require quite less number of staff.

SPECIFICATION REPORTSystem InterfaceApplication would be a self-contained system. It will not access data of any other

application nor will other application have access to its data.

User Interface

Application will be accessed through net beans. The interface would be viewed best using

1024 x 768 and 800 x 600 pixels resolution setting.

Hardware Interface

Intel Pentium III or above with

512 MB RAM

4 GB hard disk

Windows 2000 Enterprise

Edition

WAS Server

DB2 Server

Windows 95/98/2000/NT

User Characteristics

The end user of the software can be divided into two categories

Administrator: Access the system for data entry and generation of reports.

Operator: Access only for giving examination only.

BOTTLENECKS IDENTIFIED IN EXISTING SYSTEMThe first problem is that there are loads of hard copied documents being generated. This

brings us to the age-old discussion of keeping information in the form databases versus

keeping the same on sheets of paper. Keeping the information in the form of hard-copied

documents leads to the following problems:

1. Lack of space It becomes a problem in itself to find space to keep the sheets ofpaper being generated as a result of the ongoing discussion. The documents being

generated are too important to be ill-treated.2. Filing poses a problem Filing the documents categorically is a time consuming

and tedious exercise.

3. Filtering is not easy It becomes hard to filter relevant documents for theirrelevant ones if the count of the same crosses a certain manageable number.

4. Reviewing becomes time-consuming All the process done manually at thecenters and all the records are maintained on the papers. So the maintenance of the

record is very difficult in the departments and as well as its very difficult for the

workers to check the record. The Existing system is paper based, time consuming,

monotonous, less flexible and provides a very hectic working schedule. The chance

of loss of records is high and also record searching is difficult. Maintenance of the

system is also very difficult and takes lot of time.5. Result Processing is slow due to paper work and requirement of staff. NEED FOR THE NEW SYSTEM

To solve these problems they required a computerized system to handle all the works.

They required application that will provide a working environment that will be flexible and

will provide ease of work and will reduce the time for report generation and other paper

works.

AIMS AND OBJECTIVEThe main purpose behind the proposed system is to provide a comprehensive

computerized system, which can capture, collate and analyze the data from

these wards and evaluate the impact of the program.

As this system is based on Java technology, so for normal operation minimum of 64 MB

RAM will be required. And java should be installed.

Assumptions

In general it has been assumed that the user has complete knowledge of the system that

means user is not a nave user. Any data entered by him/her will be valid. To make thesoftware as user friendly as possible but at the same time keeping in minds user

requirements.
