PROBLEM DEFINITION

The student mark analyzing system is a system used for conducting the exam, analyzing

the answers, calculating the grade and displaying the result. In this system the student

details were present already in the database. The student appears for the exam and enters

the answers as required. During the course of the exam, the supervisor monitors the

student who writes the exam. The analyzer checks the paper and assigns the marks. Then

the system is used for analyzing the percentage and the grade of the student. The

administrator and students can view their results by logging into the system.

OBJECTIVE OF THE APPLICATION

The ultimate goal of this project is to develop a database to integrate the process of the

writing of the exam and assigning the scores to the student and also a way of displaying

the result.


SIGNIFICANCE OF THE APPLICATION

The significance of the project includes the following key features

The examination can be conducted in a secure environment.

Once the papers have been submitted the analyzer can enter the marks into the

database.

The system assigns the grade automatically based on the marks secured by the

student.

The marks can be easily updated.

The students can easily check their scores.

Access to database can be setup on username / password basis with multiple users and privileges

FUNCTIONAL REQUIREMENTS:

Verifying details Supervisor verifies the student details before the exam.

Answering The students should answer the questions within the given time limit.

Evaluation The analyzer evaluates the answers and awards marks for the correct answers.

Calculating grade The system generates the grade for the students based on the percentage they have scored.

Store the results The administrator stores the results in the database

Display the results The students view their result by logging into the system.

TEST PLAN

Overview

Test plan objectives To ensure that the Student mark analyzing system will:- Function consistently and reliably in accordance with current

business operations.- Meet or exceed user requirements and technical specifications.- Not adversely impact other systems or the existing technology

environment.

Testing Assumptions - The student details which have to be verified were already present in the database.

- It is assumed that student can view the results using the system which is already tested.

Risks & Contingencies The following risks apply to the testing process and may impact either the proposed date of readiness for the deployment of online reservation system, or the comprehensive level of testing that can be performed in each of the Functional Units:- The actual deployment of student mark analyzing system may

take longer to perform than anticipated, as the conventional mark analyzing system is also using the same database.


RESULT:

Thus the Problem analysis & Requirement Analysis and various Use case scenarios ,UML diagrams, Test plans has been studied successfully.
