Computer science project work

This program is very useful in real life situation for
providing instant information of Employees working
under any company, department. It also stores the
information about employees monthly salary, employee
id and designation.
In this c++ program we can modify , add, delete, recall
and list the records.
Being OOP concept available, we can add or remove
function anytime we need and even add classes and
derived classes for further improvement of the program
Without recording.

To make this project we have taken source from a book
“Computer Science With C++” written by Sumita Arora
and “let us c++” written by Yashwanth Kanethkar.
And taken help of our computer teacher Mr. A.K Shukla
sir.

We would like to thank our computer sir Mr. A.K Shukla,
who provided us this opportunity to make a project on
“Employee Database Management System” which really
helped us to understand the concepts of C++ computer
programming.
