QUIZ SYSTEM

AIM:

To analyze and design a QUIZ System using UML (Unified Modeling Language) diagram. PROJECT SCOPE:

The QUIZ System is designed & developed to evaluate the competency of the person taking the quiz. PROBLEM STATEMENT:

Developing a quiz system which includes both the user and the administrator  wherein the administrator is privileged to prepare the qu iz questions for the users based on the selected category. The user is allowed to take the quiz by choosing the categories displayed. The competency of the user is evaluated at the end by displaying the score obtained by the user in the quiz that he undertook. The quiz system can be used to evaluate the competency of the person taking the quiz. ABSTRACT:

The administrator has to login to the system and e nter the questions according to the quiz category.The quiz database is integrated with the front end.The user can choose the category in which he would like to take a quiz.The score of the user is calculated and displayed at the end of the quiz session.

MODULAR DESCRIPTION: 1. Administrator Login

In the login form the Administrator enters the username and password. The system verifies the Administrator and grants access.Verify the username and password that is given by the administrator.If the username and password match, the system grants access to the Administrator  2. Adding Questions

After verifying password the Administrator chooses the category and enters the questions into the database. The Administrator chooses the category under which he wants to enter the questions.The Administrator enters the questions, options and corresponding answers.The questions, options and answers are updated in the database.

3. User taking the quiz. In this form the user takes up the quiz and answers are evaluated comparing the options with the correct ones and the score is displayed. The user selects the qu iz category. The user enters the options for the questions.The score is evaluated and displayed.
