Understanding MVC

When building backend applications, one of the most essential design patterns you'll come across is MVC. It helps organize your code, makes your project easier to manage, and promotes clean architecture.

MVC stands for:

▪ Model - Handles the data and business logic of your application. In a Spring API, the model is usually a Java class (entity) that maps to a database table.

▪ View - Displays the data to the user. In backend APIs, this is usually JSON returned to the frontend.

▪ Controller - Acts as the middleman between Model and View. It receives requests, processes data, and returns responses.

This pattern separates your application into three core components, each with a clear responsibility.

Why use MVC?

✅ Separation of concerns

✅ Easier maintenance

✅ Better collaboration between frontend and backend

✅ Cleaner, testable code

If you're just getting started with software development, learning MVC is a fundamental step. Once you understand it, building APIs becomes much more intuitive.

It's not just common—it's foundational.
