re. Inroduction. Well I suppose it depends on what you feel are the "fundamentals" of our work in DB design. Personally, concepts such as natural business keys (the author jumps right into physical issues ala surrogate keys and misses this concept completely), historical record keeping concepts, etc. ARE the fundamentals, from my experience as a trainer.

I just think this is a primer based on someone's mixing up physical with conceptual and logical DB issues- a serious flaw that is the bane of our industry in my opinion...
