ADF model layer
The ADF model layer is the architectural element that will allow the UI layer to interact with the data layer. The model layer is responsible for providing the key business services that are available in the view layer. The information is bound to the UI component with the help of the bindings defined in the page definition file. The PageDef file that is created for each ADF bound view holds the binding definition for the view's UI components to query data from the business service. The following screenshot explains the relationship between the UI page and the page definition file. Here we can see that the Empno column in the UI is mapped to the Empno attribute exposed from the EmpVO1 entity through the Data controls pane. The table data displayed in the UI uses the collection model of the EmpVO1 collection binding. Collection Model is the object that holds the collection of rows returned from the VO query in the row set. The binding will make use of the EmpVO1Iterator module...
