Then he will have mimicked a 1970's pointer chain DB in SQL instead of
making this a properly designed RDBMS.
For example, if I use an VIN for an automobile, I can verify the VIN
by going to the automobile, the DMV, insurance company, etc. But if I
use a GUID (or any other hardware generated value), I have no trusted
external source for verification.
I do not have a good way to validate it, in fact. The magical
universal GUID might be used for an automobile, a squid or Britney
Spears!
