Hi,
Say I have an entity A on the left and entity B on the right in the ER diagram. Now if the situtation is such that any entity instance in entity type A is associated with all the entity instances of entity type B, how do I represent it in the ER diagram? How is it different from the 1:M or M:1 or M:N relation type? Bye Received on Tue Feb 14 2006 - 21:53:36 CET
