What is the role of the model in the Model-View-Controller architecture?

In MVC architecture, the Model is responsible for managing data and business logic. It:

• Stores the application's state and data.
• Handles data operations such as validation, calculations, and database interactions.
• Provides an interface for data access and modification, used by the Controller and View.

The Model does not handle data presentation — that is the View's task, nor does it process user input directly — that is the Controller's task. Thus, the Model serves as the central component that encapsulates data and business rules, ensuring a clean separation of concerns in the application.
