I still actually have that book (largely because it's where I got the line =
in my sig from) and in that version it quotes George Koch (Oracle7, The Com=
plete Reference) as saying "No major application will run in Third Normal F=

orm". Kevin's book was actually written in 94, but you were pretty close.

I had a scan through the 10g version of the complete reference, and can't s= ee that same quote anywhere.

I first saw this in the first editon of the Official Oracle DBA Hanbook, =

published by Oracle Press; the edition which covered Version 6 and the =

beginnings of Version 7.(circa 1993) I no longer have that book, but I =

remembered it being in the 8i edition. I found it on page 323, where =

it has disappeared from more recent editions.

The reason for bringing this all up is that 10 years ago, this was reasonab= le
advice. In the systems I have worked with in the last two years, I have honestly never come accross a situation where denormalizing was ever needed= .=

In fact, we have had several situations where the solution was to re-normal= ize an old denormalized design.
