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:
