I am looking at some DB2 performance-tuning notes where I am seeing a phrase
I've not seen before. The notes speak of a test in a WHERE clause that
allows a row to be definitely exluded being a "Boolean Term". The converse
is referred to a non-Boolean term.

A quick Google tells me this terminology is not widely used outside DB2. Is
there a more widely understood term meaning the same thing?

I think the terminology is only used with db2 for z/os. Anyhow, I
googled and found:
