What you're calling the table/structure descriptive is a symptom of
impoverished namespace tools, or someone's exposure to the same in
previous work.  Query languages can name columns unambiguously using
classic structure.member syntax.  Nothing is added by the redundancy.
Consider:

	select cu_name from customer
	select * from customer, locations where cu_name = lo_name

Versus:

	select name from customer
	select * from customer c, locations l where c.name = l.name

Anyone see any advantage of the first form?
