Hi Siva,
1) what is difference between module and mediation module
A mediation module can be used only for protocol Transformation and Routing wheras a Module has lots and lots of functionalities such as you can have a Business Process, Interface map, different types of Imports and Exports etc., Architectural Perspective - Mediation Module is available if you have installed ESB. Both mediaton Module and Module are available when you install WPS (As WPS sits on top of ESB).
2) what is difference between business object and business map.
In simple terms A Business Object is analogous to
Java bean. Ofcourse Business Object is more complex and provides more functionalities. Now coming back to your actual question, by 'Business map' if you mean Business Object map then a Business Object map is the transformation between two different types of Business Objects. Its a GUI editor in WID which shows mapping of elements between two business Objects.
I am a newbie to WID too but I am pretty confident that my above understanding is correct.
Thanks,
Sunil
