Thanks for your reply. After days of reflection I've drawn my conclusions. I think that Sun's business domain model is a coarse grained design (class diagram) of entities involved: there are only main entities depicted. I 'll try not to miss any requirement and relationships between them but my final design (class diagram) will be a little more complex than the Sun's one. The DB structure, too will be a little different. I'll try too not to add somethings that is not specifically required. Please tell me if i'm wrong!!! Any suggestion will be greatly appreciated....

My assumption is that a MonthlyUsage is an aggregation of consumption events (data, minutes, texts). This assumption is not based on any technology, it's just common sense.

I have made the same assumption and slightly updated physical domain model. I will let you know if I pass ;)

Folks I passed in Oct2011 with WPC. I did make subtle changes to domain model but made appropriate assumptions and documented them as well as the changes. Don't worry this is what an architect faces in reality.
