Jeff,

>This is big subject for me - one of which I'm currently struggling with in terms of redesigning my middle tier biz classes to support the handling of record sets. My problem is that I'm compelled to know all the possible combinations of how everything (ADO, XML, SQL Sever, blah, blah) interacts such that I can come up with the best schema possible. I don't think I'm alone in this struggle and any comments you have concerning such a comprehensive design would be much appreciated, John.

And a great subject for a chapter in John's next book, I'd say. How about it John?
