Explain about Oracle ADF Architecture?
Applications  build using the Fusion web technology stack achieve a clean separation of business logic, page navigation, and user interface by adhering to a model-view-controller architecture.

• The model layer represents the data values related to the current page.
• The view layer contains the UI pages used to view or modify that data.
• The controller layer processes user input and determines page navigation.
• The business service layer handles data access and encapsulates business logic.
