Multiple SP calls in an AppModuleImpl class

Question

Hello,
I have a question about the ApplicationModuleImpl class. The application we are building will include many Database Stored Procedure calls and View Object invocations. My understanding of the ADF framework and best practices is that these calls are to be coded in the AppModuleImpl class. Theoretically we are looking at many methods (one for each Stored Proc call and VO invocation) exposed via the Client Interface to be accessed by the Controller. Each of these methods is going to require its own Exception handling. How is all this best structured?
Just looking for suggestions based on your experiences.
Thanks.

There are some different approaches you can follow. In general I would try to group the SPs an VOs into logical groups (meaning they do work on a common part of data or together are used in a use case to fulfill the business logic).
For this you can use ApplicationModules (e.g. PersonAppModule, ProductsAppModule, BookingAppModule) which you later put together in one root application module (you add them all into one application module). The root application module is the facade to your business logic and only contains common logic and the nested smaller application modules.
This way you get smaller interfaces and have some logical structure which allows better maintenance.
