Brian Beckman recently had a deep technical chat with Sam Druker about the Entity Framework data model and related technologies.

Sam is GM of the Data Programmability Group at Microsoft and also happens to be Brian's boss and former programming colleague. Sam's a very technically-inclined executive... He has to be considering he's a leader in the Microsoft group that makes SQL and the plethora of data-related platform technologies, not to mention that he has to manage the likes of Erik Meijer and Brian Beckman.

This interview is great for two simple reasons. The first reason is that, well, it's a great (and deep, including whiteboarding) conversation between experts that spans many technologies related to SQL and the Entity Framework.

The second reason is that this is the first in a series of interviews on Channel 9 that involve experts in one domain (or many domains, like Brian) who interview other experts in another domain that is not well understood by the interviewer (so, in this case, for example, the venerable Brian Beckman really does not ask any questions that he already knows the answer to. Brian is not an expert in EF, but possesses a very unique perspective in this case given his mathematical tendencies and expert level understanding of things like set theory...). Yours truly, Charles, takes part in the conversation of course, but I'm mainly a camera guy who throws in a random question once and a while. Brian drives this interview.
