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
