Диаграмма распределения атрибутов eERM eERM attribute allocation diagram

дословная выписка

If ERM attributes were included in these models, they would no longer be legible. eERM attribute allocation diagrams enable you to assign ERM attribute allocations to every entity type and relationship type in a separate model. The object type of the eERM (entity type or relationship type) can be included in this model as an occurrence copy, and the relationships to the ERM attributes can be modeled. It is possible to distinguish whether the linked ERM attribute is a key attribute, a foreign key, or a descriptive attribute.
