I think this is a common terminology issue - lots of people think
"relational" refers linking tables together (foreign keys), and not the
mathematical definition of a relation as a subset of T1 x T2 x ... x
Tn -- i.e. a table.
If I haven't seen further, it is by standing in the footprints of giants
