About EJBs and the Oracle Application Development Framework

For developing web-based Enterprise JavaBean (EJB) applications, JDeveloper provides the Oracle Application Development Framework (ADF). ADF simplifies the application development process by implementing the J2EE design patterns. Web applications built using ADF follow the Model-View-Controller (MVC) design pattern.

The MVC design pattern is an application architecture that separates a web application into three distinct layers:

Model - The model represents the business services of the application
View - The view is the portion of the application that the client accesses
Controller - The controller controls the flows and actions of the application and provides seamless interaction between the model and view.
