Sorry for my bad English, probably I didn't explain well what it's my problem.
I know how to choose and put relationships in a E-R diagram (I use ERWIN 4.1).

The point is : how to set "attributes" in a relationship?

Attributes are well defined in the theory of database design as "properties" of entities and relationships. In ERWIN is very easy to set attributes for entities; unfortunately it seems to be not so easy (perhaps impossible at all) for relationships.

Regards,

The Oyster
