How many sets of Integers are there? This is why Codd (and Date even more so) argued against redundant duplicates. Thus, a tuple has no repeated columns; a table (a set of tuples) has no dups in their model; a schema (a set of tables) has no dups in their model. Received on Tue Apr 30 2002 - 00:23:52 CEST
