The Java ee architectural design pattern for the enterprise application is known as model-view-controller architecture.IT allows to separate the application logic from the user interface.It identifies components in an application as having different functions.
Model-The model of an application contains the business logic.It is implemented using EJB’s
View-IT focuses on presentation of the business logic.It is repsonsible for the consistency between the data presentation and the model changes.It is implemented using JSP’s.
Controller-It provides interaction with the client and thus it serve as a link between the model and the view.It is implemented as a servlet.
