Ken,

The walkthrough in that blog entry (http://blogs.msdn.com/b/adonet/archive/2010/07/19/absolue-beginners-guide-to-entity-framework.aspx) is a model-first approach. He is actually creating an entity model from which the database is then created. It happens that, in this case, there is little difference between the entity model, and some 'ad-hoc classes", but it is a real entity model.

I would be interested in using NORMA to create a conceptual model, from which the entity model would be generated. I would probably use the NORMA-generated DDL to create the database, since I believe it will do a better and more accurate job of creating indexes and such physical-level artifacts.

Data Quality & Entity Models

Ken, I'm no expert in this area - I have no idea even what the formal definition of an entity model is (I believe that came "after my time" in school).

My point was simply that, to whatever extent there's a distinction between an entity model and a set of "ad hoc classes", then what one designes in the EF designer is a "real" entity model, and not just some "ad-hoc classes". That is, it's as much an entity model as any entity model can be.
