The wikipedia article on Codd's Twelve Rules (looks like a Baker's Dozen to me, maybe one is allowed to ignore any single one of them!) says:

The system must support at least one relational language that
(a) Has a linear syntax ...
What did he mean by linear syntax? Does it have something to do with relational closure?
