SQL is inadaquate to the task of fully utilizing the RELATIONAL MODEL because it doesn't have any way to EXPRESS RELATIONSHIPS other than "table".
Isn't this a limitation of the relational datamodel itself? I think only the entity-relationship model can distinguish between relationships and other data. Once you convert you're model to the relational datamodel, you've lost that distinction. This is not an SQL-specific problem.
At least this is what we learned at our university on a database course.
