Home -> Community -> Usenet -> comp.databases.theory -> Question about relationship and composite pk
Hi all,
Is it possible for a 1 to many relationship to have (1,1) Cardinality on both sides of the relationship?
Are composite primary keys a bad thing? The table I have consists of only the two attributes which ocur many times, but only together once.
Thanks. Received on Mon Mar 19 2001 - 15:36:48 CST
