Jared,

I agree completely with your disagreement, except that I don't agree that you should have disagreed since we actually agree. You did say it better, though. :)

unnormalized != denormalized

(etc.)

As far as I know, structured denormalization is considered to be a method for modification of a normalized design. There should be disipline/method/rules that try to get the best performance increase in a trade-off for the least collateral damage (extra coding).

I get the impression that this is standard operating procedure, documented in industry journals, and so forth.

In your experience, what percentage of "real world" dbs are using pure normalized designs?

Has this changed as hardware becomes more powerful and cheaper?

ps, liked the popcorn eating method, feedbags can also be found at livestock supply places

pss, aren't you *ever* going to tell us what happened at your last job?
