For those who aren't aware of his work, Hugh Darwen has written a companion to his relational theory book, which can be read in parallel. The theory book makes its points with Darwen and Date's Tutorial D teaching language and the companion book uses SQL to make the same points - or not where SQL is incapable!

I'd say the perspective is pretty unique, since Darwen spent years on the SQL standards committee while also being a severe critic.
Both books are free pdf downloads at bookboon dot com. You do have to
put up with embedded ads which personally I don't find troublesome, being as I am a fan of the author who I think is one of the few public deep thinkers about not just the theory, but the applied theory. Received on Wed Nov 21 2012 - 23:54:15 CET
