How would you describe the connections established in the MVC architecture?

In MVC (Model-View-Controller) architecture, the following relationships are established:

1. Model → View: The Model sends notifications to the View about changes in its state. The View subscribes to these notifications to update the data display.

2. Model → Controller: An indirect relationship. Changes in the Model can indirectly influence the Controller's logic, which in turn can update the View.

3. View → Model: The View does not directly modify the Model's data. It sends user actions to the Controller.

4. View → Controller: The View sends user actions (e.g., button clicks, text input) to the Controller. The Controller processes these actions.

5. Controller → Model: The Controller interacts with the Model by calling methods to change data in response to user actions.

6. Controller → View: The Controller selects the appropriate View or sends data to the View for display after processing user actions and updating the Model.

In summary, the Model manages data and business logic, the View displays data from the Model and reacts to user actions, and the Controller acts as an intermediary, handling user actions, interacting with the Model, and selecting the appropriate View.

Interaction example:

• The user clicks a button in the View.
• The View notifies the Controller about the action.
• The Controller requests data change from the Model.
• The Model changes the data and notifies the View about the change.
• The View updates its display, showing the new data from the Model.
• (or) The Controller can retrieve updated data from the Model and explicitly instruct the View to update the display.
