I've generally understood the terms more like what is described near the top of this page: http://en.wikipedia.org/wiki/Relation_%28database%29 "In SQL, [...] a relation variable is called a table." I'll admit that how these terms are treated depends very much on the source, and we should define our terms to avoid confusion. But defining a relation as set of records, and a table as a variable which holds a maintainable "concrete" relation (or something more or less to that effect) makes some sense to me. -Kevin
