Chapter 5. Binding the Data

Validation has been completed for our business components and we are now at the stage where we will expose the underlying business service to the outside world. The components involved in exposing the services to the view layer are simple with the help of ADF data control layer. The data control layer abstracts the implementation logic of business services and provides a common metadata interface to access the operation, data collection, and properties. Data control is based on service-oriented principles to decouple service integration from the view layer. In this way, the service and the user interfaces for the service are separated, and the implementation logic for the business service is abstracted.

In this chapter, we will learn about:

• ADF model layer

• Data control

• Binding the data

• Working together with the data control layer and binding

• Creating page definitions
