Since when did this become a requirement or property of a relationally complete system? Is this a case of the tail wagging the dog?
Here is the logic as I see it:
1. I support the notion of and deeply desire a unity between RM and an open ended collection of scalar types.
2. The framer of the relational model used the term atomicity which impedes this objective.
3. Thus, the framer's formalisms are flawed and outdated. We will use new "corrected" definitions.
I am yet to be convinced, but I'm willing to be open-minded and think about
it some more.
