Question

Quizplus · Accepted Answer

In IDEF1X, extended E-R model 1:N relationships are called nonidentifying connection relationships. These relationships are non-specific and do not identify the entity on the "1" side of the relationship uniquely. They only establish a connection between the entities. Identifying connection relationships, on the other hand, identify the entity on the "1" side uniquely. Category clusters and nonspecific relationships are not related to 1:N relationships in IDEF1X.
