Assignment - Change or not to Change the Business Domain Model

[Carlos Borges]

Hi! I'm facing the 1Z0-865 and, despite everybody says that It is not good to change the Business Domain Model (BDM), I think that It is not possible to fulfill all the requirements of the Use Case Specifications (UCS). I will give you an exemple:

Pretend that the BDM give a SOUP class that is associated with a VEGETABLE class. Despite of that, in the UCS, the assignment says that "the SOUP is made with healthy ingredients (VEGETABLES and MUSHROOMS)".

So, what do you think that I have to do? Create a HEALTHYINGREDIENT class and use It instead of VEGETABLE class; or forget the UCS and use ONLY the VEGETABLE class as given by the BDM?

I believe that instead of vegetable you can make it IIngredient as interface and Vegetable as concrete type of that interface. Then you can change the BDM to associate a soup with ingredient rather than vegetable.
