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