What is the MVC architecture?

MVC (Model-View-Controller) is an architectural pattern that divides an application into three interconnected parts:

• Model: Contains business logic and data. It does not know about the View or Controller. The Model handles data requests, updates its state, and notifies observers (e.g., the View) of changes.
• View: Responsible for displaying data from the Model and interacting with the user. It does not contain business logic. The View retrieves data from the Model and displays it, as well as sending user actions to the Controller.
• Controller: Acts as an intermediary between the Model and the View. It accepts user input from the View, processes it (possibly calling the Model to update data), and determines which View should display the result.

The interaction occurs as follows:

1. The user interacts with the View.
2. The View sends a request to the Controller.
3. The Controller processes the request, interacting with the Model (retrieving data, updating it).
4. The Model notifies the View of changes.
5. The View updates its appearance based on the data from the Model.
