What are layers in Oracle Architecture?
Oracle Application Development Framework has a MVC(Model View
Controller) architecture. There are three layers:
- Model- Handles interaction with data sources. Model is based
on JSR-227.
- View- Handles the user interface. It used HTML and Java
components. This layer can be web and client based.
- Controller- Handles application flow between model and view.
This is to say, it manages the flow between the web pages.
