Denormalizing is only appropriate when solving performance problems, and = NOT to make a developer's life easier.

Yes, and sometimes denormalizing ad nauseum will cause performance problems... What works on paper and what *really* works is not always exactly the same. On paper SQL Server works. ? Sorry, couldn't resist!

Does anyone have any good reasons why a database's logical model would differ from the physical model?=20 Haven't run across any good business reasons why this should/would happen.
