Fiori MVC (Model-View-Controller) Architecture is a design pattern used in SAP Fiori applications that helps to separate the presentation layer from the business logic and data layer.

In this architecture, the model represents the data and business logic, the view represents the user interface, and the controller acts as an intermediary between the model and view to manage data flow and user interactions.

The model layer contains the application data and business logic, such as database queries and data processing logic. The view layer represents the user interface and is responsible for displaying the data to the user. The controller layer manages the flow of data between the model and view layers, and is responsible for handling user interactions and events.

This architecture provides a number of benefits, such as improved maintainability, scalability, and testability. By separating the concerns of the application into distinct layers, it is easier to make changes or updates to a specific layer without affecting the others. This helps to ensure that the application remains flexible and adaptable to changing business requirements over time.
