My latest MSDN column is available in the August issue and called "How Data Access Affects Database Performance". It was inspired by a problem that one of my DBA friends noticed in the database that could only be fixed by changing the data access code.

I noticed that there were two articles in the issue on EDM and, although I'm using native ADO.NET code for examples, I mention how EDM-generated code fits into one of the common cases.

I hope the information is useful.
