OA Framework Architecture..

OA Framework is based on the industry-standard J2EE MVC design pattern. Developers manipulate the application's metadata using Oracle JDeveloper OA Extension, while OA Framework uses the most efficient manner to execute the application. The MVC architecture is a component-based design pattern with clean interfaces between the Model, View, and Controller. The Model is where the application implements its business logic. The View is where the application implements its user interface and the Controller is where the application handles user interaction and directs business flow.
