Can someone clarify when to use a Model vs. an Entity in MDS? It seems in most cases a Model and Entity share a 1:1 relationship. If you relate this to a dimensional model, would and MDS Model = Dimension or would Entity = Dimension?
Also, is it typical to have a "Date" Model in MDS that will be used as the Date dimension within dimensional models? I've seen "Product", "Customer", and "Geography" mentioned plenty of times as examples of Models, but never "Date" which seems to be even more ubiquitous than Geography so I wasn't sure if I was understanding the concept of a Model correctly.
