You are correct, NEO.
"Color is NULL" is the absence of an assertion about color. Why is it NULL? Maybe the data entry person left a field blank.
Maybe the current object is an idea, and ideas don't have colors.
As far as "divergence from reality" goes, a database doesn't represent reality. It represents what we think we know about reality. The difference is subtle but important. Received on Sun Apr 25 2004 - 07:22:16 CDT
