ERD - Attribute of a relation

[xavierpaul]

Hello,
I'm drawing a Data model with the ERD diagram, and I would like to know if it's possible to connect an attribute to a relation (and how).

As these are defining Concptual or Logical level data modeling I am not aware that ERD's directly support defining a Relationship based on a specific Attribrute. The relatioships are Entity to Entity. However you can set the Connector fields (e.g. name) to represent the general attribute involved in the relationship.
