Student Management System API

Build a full REST API for managing students, courses, and enrollments — full CRUD, relational data, and clean endpoint design. The classic backend project, done properly.

You will learn to:

• Design relational database schemas with foreign keys and join tables
• Build a complete REST API with all standard HTTP methods and status codes
• Implement input validation and meaningful error responses
• Test API endpoints systematically using Postman or Thunder Client
• Write clear API documentation in README with examples
