A view on Java Persistence Entity Join Column's "name" and
"referenced column name" attributes and Entity Data Model Referential
Constraint's dependent and principal roles respectively. Each java
persistence entity with properties annotated with Join Columns are
transformed into Referential constraints and Referential constraint roles.
</p>
<p>
The implementation of the view provides access to EDM referential constraint
roles created from Java Persistence Entity Join Columns. The implementation
acts as a container for EDM referential constraint roles. A referential
constraint role is consistent only if the principal role and dependent roles
can be created from JPA Entity relationships.
