Only Oracle ADF Business Components can be exposed as data controls.

Dragging a data control onto a JSF page generates a Java class that acts as a managed bean.

An XXXpagedef.xml file holds detailed information about a JSF page’s use of data and operations exposed through ADF Data Controls.

Data controls eliminate the need to use expression language in your JSF code for binding the UI to data.

A Databindings.cpx file holds names of managed beans that you map to UI elements.
