Data Controls

The Data Controls panel lets you view the data controls created to represent an application's business services and to create databound UI components by dragging and dropping the control panel objects onto an open web page or ADF Swing panel.

The Data Controls panel displays objects to which your UI components can be bound, including data collections, attributes, and methods that the business services developer exposed through the Oracle ADF data control, as well as specific, built-in operations that are generic to all data collections.

In the Data Controls panel, the placeholder data control appears alongside other data controls in the root tree. A placeholder data control that does not yet have data types defined will have only the Commit and Rollback built-in operations available.

You can create master-detail relationships between placeholder data types, similar to the master-detail data collections in a standard data control. You can drop master-detail data types onto pages to create master-detail forms and tables.

By selecting Categories you are creating a detail data type as a child of the Categories data type. The first attribute in the master data type is the join attribute; it is automatically added to the detail data type and you cannot modify it.
