Employee Management System using Spring Boot

Objective
The main objective of this project is to develop a secure and scalable backend system for managing employee and department data within an organization. The system automates administrative operations such as employee registration, department mapping, and data management while ensuring secure access through role-based authentication.

Key Modules

Employee Module

• Add, update, view, and delete employee records.
• Assign employees to specific departments.
• Retrieve details using RESTful API endpoints.
  Department Module
• Manage department information and structure.
• View employees under each department.
• Perform CRUD operations efficiently using JPA.

Technology Stack

• Java 17 – Core programming language used for backend development.
• Spring Boot 3.x – Framework for building RESTful APIs efficiently.
• Spring Security – Handles authentication and authorization.
• Spring Data JPA (Hibernate) – Simplifies database interaction using ORM.
• MySQL & Postman – MySQL for data storage and Postman for API testing.

System Workflow Summary

• Client Request: Sent via HTTP (GET, POST, PUT, DELETE) to Controller.
• Controller Layer: Validates requests and delegates to Service layer.
• Service Layer: Contains business logic and communicates with Repository.
• Repository Layer: Performs CRUD operations with the database using JPA.
• Response: Data is returned to the client in JSON format.

Future Enhancements

• Integration of JWT authentication for token-based login.
• Development of React frontend for better user experience.
• Email notifications for updates and alerts.

Conclusion
The Employee Management System demonstrates a well-structured backend solution built with modern Spring Boot technologies. It ensures secure, reliable, and efficient handling of employee and department data.
