title: How to represent a descriptive attribute of a relationship in ERwin modeler?
body: <p>In the modeler, relationship is represented by a line between two entities. It would be no problem if the relationship has no descriptive attributes. But if it has, how can I represent the descriptive attributes? For example, the relationship set <code>advisor</code>, between entity set <code>student</code> and entity set <code>instructor</code>, has a descriptive attribute <code>date</code> to record the data an instructor become the advisor of a student. How I can represent the attribute? </p>
