ABSTRACT

The “Leave management system” software is user-friendly software. The main

objective of the system is which shows and helps you to collect most of the information about

Leave details of students.

The project Leave Management System includes student login, staff login. Student

login enables students to view their attendance details and also their leave status. They can

also apply for the leave. Staff login enables staff to confirm the leave applied by the students

of their class. They can either accept or reject the leave. Staff can also generate various

reports on the leave details. Attendance percent of the student calculated automatically and

updated. Students cannot apply for more leave when their attendance percent is below

minimum.

The Leave Management System can be entered using a user id and password. It is

accessible either by a student or staff. Only they can add data into the database. The data can

be retrieved easily. The interface is very user-friendly. The data are well protected for

personal use and makes the data processing very fast. This project has been developed usingC language as a front end and back end as oracle.

Design Documentation

This project is a Leave Management System. This system maintains the Leave details and attendance

details of students.

This section describes the high level design of the Leave Management system. The system has the

following modules:

1. Login: Accepts the user id and password. Validates the user id and password. If valid then

appropriate main menu is displayed. Otherwise a suitable error message is displayed.

2. Student: Displays students details, leave status and application for leave

3. Staff : Displays various reports such as overall, individual and leave reports.

4. Attendance: Calculates and updates attendance percentage of student.

This section describes the detailed design of the various modules in the Leave Management system.

Code Review

52




Code Review is used to review the coding and report the user as how they can use the

variables, how to proceed with loop, array, functions and logical concepts.

S.No Module Name Function Name Line

Number

Description

1 Login Module fnLogin 20 The data type for login id is

declared as array of character.

Instead we can declare it as

int so access can be made

easy.

2 Student Module fnStudentDetails 32 Function does not display thetotal number of leaves. We

can include the code to

display number of leaves.

3 Staff Module fnConfirmLeave 49 Vaiable reason is declared as

a character array of size 50

but reason may not exceed 10

so we can alter the size of

array.

4 Attendance

Module

fnAttendance 31 The function completes the

task and it updates the outputin function itself and there is

no return of output to the

calling module. So make the

function to return the result to

calling function.

CODE REVIEW




Conclusion

CONCLUSION

The project Leave Management System has been developed based on the business

requirements. The project has met its objectives. The system reliability is high and enoughsecurity has been provided. The system is very simple in design and to implement. The new

computerized system was found to be much faster, reliable and user friendly.

As the project Leave management system consists of student details, it enables the

registered students to access the application and also students can apply for leave, the leave

details are stored separately. In future we have planned to make this project online process by

adding extra modules such as add student, remove student, add class and etc, so that new

student can register their details online and can apply for leave through online.
