Chapter 6. Introducing the Application Module

In the previous chapters we have discussed the business components that build the data model for your application. Now the question that you may have in your mind is, how does Oracle ADF expose that data model and business methods to the client for use? Before answering this question let us take a step back and see what is missing from the picture, as we put all the pieces together from our discussion so far. One thing you may surely notice is that we have not yet discussed about a service layer which act as an interfacing layer for the business model implementation. In this chapter, we will learn about the application module component, the service layer for the business components stack. We will be discussing the following topics:

• Concepts and architecture

• Core features of an application module

• Defining an application module

• Sharing of application module data

• Nesting application modules

• Working with an application module
