Query: Where's the beef?

I found the book poorly written and researched. The title is ADO.NET Database programming. What is offered is 5 chapters on DB design, 2 on ADO access and a couple more on XML. The author states he uses an older version of MSDE ( version 7) and discounts MSDE 2000 and Access databases. The latter being non-enterprise or desk top databasing. The meat of chapters 6 and 7 for ADO failed to explain the internals of use of the ADO objects. I returned the book and deemed it a failure. I've since bought Microsoft's ADO.NET Core Reference and found that it answers my questions.
