Possibly... I've seen very few live databases with more than a few tables,
that were ever normalized; often redundancy is built back inot them because
some DBA thinks it is a good idea :-)

Even if we had a perfect database, there is still a case for making it
smart. There are functions (particularly with Dates) that are much better
suited to "back end" processing than doing them in application code.

Again, mileage may vary :-)

Yes, I have used triggers for this purpose when dealing with sensitive data.

Does this include Unix PCs?

My wife has Parallels running on her Mac, which runs a Windows VM.
Another company has come out with one that I've read grabs a processor
and thus runs Windows faster - as a single-processor system.

I wonder what other VMs in mainframes and elsewhere do this.
