Online Quiz System has to be developed for conducting a quiz as part of Department Technical symposium RECCA.
The System developed should contain following features
1. The number of participants should be of 30.
2. The duration for quiz is 30 minutes so a timer has to kept which should show time duration.
3. The number of questions should be 40 chosen randomly from the database in 3 different areas namely
i) Information Technology  ii) logical reasoning and iii) General Knowledge.
4. The questions should be of objective type with multiple options. For each correct answer the participant will receive 1Point and wrong answer .25Point will be deducted for each wrong answer.
5. At the end of the quiz the user score will be displayed.
6. Once a Student answered for question he can’t changes his answer later.


2.1Brief Description
The use case describes how a Participant logs into the Quiz System

2.2 Flow of Events

2.2.1 Basic Flow

This use case starts when the Participant wishes to Login to the Quiz System
1. The System requests that the participant enter his/her name and password
2. The participant enters his/her name and password
3. The System validates the entered name and password and logs the participant into the System

2.2.2 Alternative Flows

Invalid Name/Password
If, in the Basic flow, the participant enters an invalid name and/or password, the system displays an error message. The participant chooses to either return to the beginning of the Basic flow or cancel the login, at which point the use case ends.

2.3 Special Requirements

The Number of participants should be 30

2.4 Pre-Conditions


2.5 Post-Conditions

If the use case was successful, the participant is now logged into the system. If not, the system State is unchanged.

2.6 Extension Points


3. Select Options to Answer

3.1 Brief Description

This use case allows the Participant to select appropriate answer to the question.

3.2 Flow of Events

Quiz System Supplementary Specification

1. Objectives

The purpose of this document is to define requirements of the Quiz System. This Supplementary Specification lists the requirements that are not readily captured in the use cases of the use case model. The Supplementary Specifications and the use-case model together capture a complete set of requirements on the system.
2. Scope

This Supplementary Specification applies to Quiz system, which will be developed by the OOAD students.
This Specification defines the non-functional requirements of the system; such as reliability, usability, performance, and supportability, as well as functional requirements that are common across a number of use cases.

3. References


4. Functionality

Multiple users must be able to perform their work concurrently If the Participant completes 30Mins allotted for him/her, he or she should notified with message your time slot is over.

5. Usability

The desktop user-interface shall be Windows 95/98/2000/xp compliant.

6. Reliability

The System should function properly for allotted time slot and produces score card with no more than 10% down time.

7. Performance

1. The System shall support up to 500 simultaneous users against the central database
At any given time and up to 500 simultaneous users against the local servers at any one time.
2. The System must be able to complete 80% of all transactions within 2 minutes.

8. Supportability


9. Security

1.The System should secure so that only registered participant can take part in Quiz.
2.Once the participant had answered for a question he/she can’t change the answer later.

10. Design Constraints.

The system shall provide a window-based desktop interface.
