Answer from AI
In the architectural pattern MVC (Model-View-Controller), dividing the application into three components helps organize code and simplify maintenance:
-
Model — responsible for data and business logic. The model manages the application's state, interacts with the database, and performs calculations.
-
View — responsible for displaying data to the user. Presents information from the model in a user-friendly format (e.g., HTML page, graphical interface).
-
Controller — handles user input, interacts with the model, and updates the view. The controller receives user actions (e.g., button presses), modifies the model, and determines which view to display.
Example:
- The user presses a button (Controller receives the event).
- The controller updates data in the model.
- The model changes and notifies the view.
- The view updates the display.
This separation improves modularity and makes testing easier.
