Back to Basics: What is MVC Architecture?

This explanation is simplified for beginners, so some technical details have been omitted. 🙏
I hope you read it with the mindset of "getting a general feel for it first!"

🚩 The Roles of Each Component

Model

The part that manages data and logic

Responsible for the data itself, as well as the rules and processes for manipulating that data (Business Logic).

Using a cooking analogy, the Model plays the role of a recipe book that contains the ingredients and the cooking methods.

View

The part that users see and interact with

Responsible for the screen design and the parts viewed by the user.

Using a cooking analogy, the View refers to the finished dish itself.

Controller

The part that receives inputs such as user operations and connects the Model and View

Responsible for taking new data to be saved, passing it to the Model, and then passing the results to the View.

Using a cooking analogy, the Controller refers to the chef themselves.

💡 Why It's Useful

• Clear division of roles

  • Since each part is independent, it is easy to modify or extend.

  If you only want to change the design, you only need to modify the View.

• High reusability

  • You can create different Views using the same Model.

  For example, you can display the same data in both a graph and a list.

• Easy to test

  • Each part can be tested individually.
