CHAPTER 5Introducing ADF Business Components
“If everybody minded their own business,”the Duchess said, in a hoarse growl,“the world would go round a great deal faster than it does.”
—Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898),Alice’s Adventures in Wonderland
Oracle ADF Business Components (ADF BC) is the Oracle Fusion Java EE technology for creating business services. Business services provide object/relational (O/R) mappings, business logic, queries, transaction handling, and data access for an application. They do not provide a user interface or control flow. The view and controller layers of an ADF application communicate with business services through the model layer and provide the user interface and control flow.
