Isn't this the same problem as "what's an atomic value"? A word (a string) is composed of individual syllables and characters. So is the word atomic? - I'd say "yes", because it looses meaning if dissected. In Date's "Introduction to Database Systems", I think I've read Date's definition of "atomic" as "without user-visible parts", however that definition is still not very practical. So how is an "atomic value" defined?
