Relationship Implementations

Consider the following rules:

Only one relationship implementation is allowed per relationship membership.
A many-to-many relationship implementation must be associated with one linkage and one entry point.
A foreign key relationship implementation must be associated with one linkage.
An entry point implementation must be associated with one entry point.
A many-to-many relationship implementation technique is valid only for many-to-many relationships.
