📘 University Course Registration System

🚀 Overview:

University Course Registration System is a full-stack web application built with Spring Boot + JavaScript that simulates a real-world university management system.

This project goes beyond simple CRUD operations and focuses on:

• real business logic

• relational database modeling

• layered backend architecture

• full REST API integration

• frontend + backend communication

Students can register for courses, teachers manage courses, and the system handles complex relationships between entities.

Designed as a mini production-like system, not just a tutorial project.
