Could someone clear something up for me? As far as my understanding goes, the physical model describes how the data is represented in the context of a specific storage medium. The logical model is a representation in terms of entities and relationships, independent of any particular data management technology. How do these two work with Entity Framework? I assume the EF works against a logical model. In which case, where does the physical model fit in?
In the EDM (Entity Data Model) the first one is represented by Store Schema Definition Language (SSDL)
and the secound one by Conceptual Schema Definition Language (CSDL). But, there is also a third player in this game: Mapping Specification Language (MSL).
In the Entity Framework metadata, the mapping layer sits between the conceptual and store layers and provides the map from the entity properties back to the tables and columns in the data store.
Ef, as an ORM, works with all three. Developer codes against the Conceptual model and EF maps it back to the storage model using the MSL.
