datawarehouse architectures question

Hi,

Maybe you guys can help me out answering the following question

What are two differences between an application data model and an enterprise data model? (Choose two.)
A. An application data model is fixed while an enterprise data model is iterative.
B. An application data model requires additional semantic validation in the development phase while an enterprise data model does not.
C. An application data model reflects specific functions of the business while an enterprise data model integrates all aspects of the business.
D. An application data model is focused on how the data flows through the organization while an enterprise data model is focused on how the data is processed.

 

A least C is a right answer, but which one of the others ? Cannot find this anywhere in theory nor googling.....

Could you explain the right answer as well ?

Thanks !

Jack

Explanation of : An application data model is fixed while an enterprise data model is iterative.

 

Application data model is fixed here is termed as ( this is incremental in nature for a specific task to be acheived ), one cannot perform other business oriented task from Appliaction data model, whereas Enterprise data model is iterative, one that evolves as the business needs evolve.
