Application Module in OAF

Application Module in OAF


  • It is very important component in the Model.
  • Every Oracle Application Framework (OAF) page should be attached to some Application Module.
  • It is the interface between the Client transactions and Data Base transactions.
  • All the application module objects end with AM.
Example: employeeAM

 Whenever we create AM one subclass will generate.






Application Module is of two types:

1) Root Application Module.
2) Nested Application Module.

If we are attaching AM to the Main Region of the page then it is called Root Application Module and if we are attaching to the child regions (or) nested regions then it is called Nested Application Module.

The below figure shows what is Main region and what are child regions in OAF page.




The View Objects containing in the Main Application Module can be used anywhere in the childregions or Nested Application Module.

If the View Objects are attached to the Nested Application Module then those view objects are applicable only to that particular nested region.
