 1. INTRODUCTION
The Employee Management System aims to simplify the process of managing employee
information in an organization. It allows administrators to store, update, and retrieve
employee details efficiently. Built using Java Swing for the front end and MySQL for the back
end, the system provides a reliable solution to handle employee data.

2. OBJECTIVE
The primary objective of the Employee Management System is to streamline the process
of managing employee information within an organization. The system ensures accurate and
efficient handling of employee records and is intended for use by administrators and HR
personnel.

Interactors

 Administrators: Responsible for adding new employee records, updating details like
branch or designation, and removing outdated records when necessary.
 HR Personnel: Access employee details for administrative and organizational
purposes.
 Employees: Have their information securely stored and easily retrievable.

Functions

 Registration: Allows the administrator to add new employee details, including

Employee ID, Name, Monthly Fee, Gender, Branch ID, and Date of Joining (DOJ).
 Deletion: Enables the removal of employee records based on their Employee ID.
 Update: Facilitates updating details such as branch or designation for an existing
employee.
 Display: Provides a way to view all stored employee records in a structured format.

3. Tools Used

NetBeans IDE 8.0: A robust development environment used for coding the Java application.
For front-end design JAVA Swing has been used.

MySQL Command Line Client: A tool for creating and managing the database for backend
design, executing SQL queries, and maintaining the data.

4. Database Design
This section describes the table structure, including field names, data types, and constraints.

Table Schema:

2|Page
Table Name: Students

Field Type Null Key Default Extra

ID int(11) NO PRI NULL auto_increment

name varchar(100) YES NULL

Designation varchar(10) YES NULL

Department varchar(10) YES NULL

Contact varchar(15) YES NULL

Students Table:
"CREATE TABLE IF NOT EXISTS employees (" +
"id INT PRIMARY KEY AUTO_INCREMENT, " +
"name VARCHAR(100), " +
"designation VARCHAR(100), " +
"department VARCHAR(100), " +
"contact VARCHAR(15));";
5. User Interface (GUI) Design

 6. Java Code Implementation:
The Java code is structured into different modules for better readability and maintainability.
Key modules include:

 Database Connection: Establishing and managing the connection to the MySQL

database.
 CRUD Operations: Implementation of Create, Read, Update, and Delete
functionalities.
 User Interface: Handling user interactions and displaying data.
