It is true that tuples with a relation (table) can have any arbitrary degree but they all must be of the same degree. It is possible that different tuples with in a single relation can have different degrees?

Is this similar to the name of a set defining the type of its elements?

Couldn't a tuple be restricted by its attributes alone, where the relation it belongs to is no different that any other attribute? Or looking at it the other way, doesn't a tuple simply belong to multiple relations? Received on Mon May 19 2003 - 22:47:42 CEST
