Hi Greg;

Thanks for the clarification. As I read the following sentence, ("It‟s not uncommon for an application..."), I thought the author is saying the same thing in two sentences, one confirming the other. But I see your point that he was talking about EF!

Thanks!

Hi, Ben.

The author is saying that a data model that limits you to a single database (as the ADO.NET Entity Data Model does) is unrealistic.  The DevForce Domain Model, by integrating multiple Entity Data Models, overcomes this limitation.

on Page 27 it says:
Multiple Data Sources
An Entity Data Model maps all of its entities to tables in a single database. This is unrealistic for the many enterprise applications whose conceptual data models integrate information from multiple resources. It‟s not uncommon for an application to draw upon data resident in three or four different databases.


Shouldn't that be:
Multiple Data Sources
An Entity Data Model maps all of its entities to tables in a single database. This is NOT unrealistic for the many enterprise applications whose conceptual data models integrate information from multiple resources. It‟s not uncommon for an application to draw upon data resident in three or four different databases.
