As far as I understand it, yes. They're just different ways of saying the
same thing. It has been a number of years since I've had to deal with the
formalisms of it. Also, there may be differences when it comes to updating
the relations (insert, delete, update, etc), as I don't know just how that's
handled in the formal math of it.
