PROBLEM STATEMENT:-

Problem statement of a system describes all the real problems that exist in the present

system. The success of the system depends largely on how clearly the problem is defined,

thoroughly investigated and properly carried out through the choice of solution. A good system

model should provide not only the mechanisms of problem understanding but also the frame

work of the solution. Thus it should be studied thoroughly by collecting data about the system.

Then the proposed system should be analyzed thoroughly in accordance with the need. Thefollowing problems in the present system urge us to look for new software which can rectify

these problems and help us achieve significant technological progress:

The examination for various certification courses, entrance for any institute or

organization, etc are increasing rapidly in the world.

The problem is to arrange or to conduct these exams at different locations at

worldwide.

For this, the man-power will also increase. There will have to invest more

money for marketing and paper printing.

Due to this type of examination, there would be more chances of cheating which

is the reason of lack of interest in people.

The distance of the locations or the centre for the examination may be too long

for some candidates.

Due to this, many people cant afford as this consume more money & time.

This will be inconvenient to the people.

The results of all these exams take tedious time, so this process is timeconsuming.

The people of this generation have no time to wait for the result which is declared in months.

or by deleting. The attributes are tech-id, tech-name.

Experience Category: - This entity is used to categorize the level of questions. Theattributes are exp-id and exp-years.

Result: - This entity will display the result of the user after giving the exam. This result

will contain the total questions, total attempted question, correct answer, wrong answerand percentage. The attributes are user-id and attempt-no.

User Record: - This entity is used to store the results of the users and to store theinformation of the users such as user-id, password and code.

Online Exam: - This entity will contain the question papers of all the technologies. The

user will give examination by the help of this entity. The attributes are user-id, attempt-

no, tech-id and exp-id.

Identify Actors Administrator: - The administrator is an actor who manages and plans the whole

system or the project. The work of the administrator is to prepare the schedule of the

examination according to the selected technologies and their experiences. He can add,

modify or delete the technologies. He has to manage the question bank which containsall the questions category wise of the examination. He can modify, edit or delete any

questions of any technology or of any experience category. He can de-activate any

questions. It means if he doesnt want to give any particular question to the candidate in

the examination then he can de-activate that question. The questions from the question

bank will displayed on the screen and the exam conduction is managed by the

administrator. The administrator has his own user-id and password. He has to manage

the registration work. Then by retrieving all the user information from the user

database, he will manage the schedule of the examination. After the examination he will

manage the result and record of the previous results in the result database.

User: - Another actor is the user or the candidate who will give the examination. If the user is

new who is not registered yet, he can fill a registration form to get registered into this system.

He has to fill all the information correctly and he will be successfully registered. If the user is


10/33

EXPERIMENT-1



already registered in this system, then he has to fill the login form which contains the user-id

and password. All the users will be given unique user-id as their admit card. Then he will see

his schedule and by that schedule the question paper will be displayed in front of him

according to his selected technology and his experience. He has to complete his questionpaper in a given time period. If he completes all the questions on time, then he will submit the

question paper and at that instant he will get the result which will contain total questions, total

attempted question, correct answer, wrong answer and percentage. If he cant complete his

paper on time then also the paper will automatically submitted and the report card will be

generated.

Identify Use Cases Registration: - This use case is used by user for registering themselves in this system if

they are not registered. While the administrator manages all the users and their

information through this use case.

Login: - This use case act as an admit card. If any user wants to give the exam he has to

login successfully. If the user login successfully then he is able to give the examinationwhile when the administrator login successfully he will get another menu page by

his question paper in a given time and submit it to get the result. While the

administrator use this use case to conduct the exam for the users according to thetechnologies.

Result: - This use case will display the result of the exam on the screen of the user.

While the administrator will store the results of all the users in the result database along

with their user-id and tech-id.

Report Card: -This use case provide the facility to the user to get the print out or hard

copy of the result of the exam.

Use Cases ModelUse case diagram is used to give the description of the software or the system. It means

it shows that what facility is given to the user by the system. In this online examination

system, the use diagram consists of 2 actors- user and administrator. The use cases areregistration, login, schedule, question bank, conduct exam, result and report card. The use

cases are shown by ellipse. The association between the use case and the actors is given by

the unidirectional association. The association of both the actors with the use case is same

but their tasks are different.

The association of the administrator with the registration shows that he will manage the

user registration by maintaining data in user database. The use case login shows that when he

will login to the system, firstly the user-id and password will be checked and the menu page

will be displayed. The schedule use case shows that he will prepare schedule by fetching the

data from the user database which shows about the time table of the exam for the user. Next use

case is question bank through which administrator store all the questions of the paper and can

modify or delete the questions by using question database. The result use case is used to


11/33

EXPERIMENT-1



maintain the user result by fetching the information from the result database. The report card is

the hard copy of the result of the user.

The association of the user with the registration use case shows that if the user is new

then he has to register him first by filling this form. The login use case will differentiate theuser and the administrator and according to them the menu page will also different. Then, next

is schedule use case through which the user will see the schedule of his exam. The conduct

exam use case gives the information about the exam which is to be given by the user. The result

shows the ability of the user on a particular technology. The report card is the hard copy of the

result. If the user wants then he can take it.
