Looking for qbql, I happened on a nice post (Sept 16) by Vadim at:

http://vadimtropashko.wordpress.com/

I know as little about the machinations in 'ask tom' as I do about what goes on in the heads of the self-styled 'stackoverflow' posters mentioned here lately but talk about chasing one's tail (for nearly ten years at that)! Running around in circles because it would seem that the 'type' was there all along had it occurred to the SQL authors that a heading can be empty and therefore a tuple can be the empty set and vice versa. Instead, people are arguing about ways to re-invent a relation that's inherent and staring them in face. I think Vadim was right on when he disparaged the recording of derived info (what he called 'calculated') instead of the determining info. What a wasteful industry IT is.

Maybe there's an excuse for the original post dating 'only' four years after TTM 1st edition was published. I'll bet some of these posters are the same people who say there's been no progress in RT for twenty years, but I'd say that's only because they don't bother reading what the deeper thinkers write.
