Can't seem to find online the portion that this refers to (at least
without paying), maybe I'll have to find a library that has them all.
The ones I've seen aren't what I'd call formal, though they offer
examples and context that may be valuable for starting discussions if
nothing else.
Which sections or portions refer to 'internal' for example? Are
relation or relvar 'headers' defined by ISO?

Personally as far a db is concerned, what is immeasurable is uninteresting (by 'immeasureable' or that which we can't take the measure of, I include 'un-nameable'). Received on Thu Mar 18 2010 - 22:56:17 CET
