Description mgolden 2007-11-01 00:54:20 UTC 
Version:            (using KDE KDE 3.5.8)
Installed from:    Ubuntu Packages

I quite frequently use association classes.  An association class "hangs off of" or modifies a relationship between two other classes.  In the diagram on the URL below, there is a many-to-many relationship between flights and frequentfliers.  When a frequentflier boards a flight, she can get some arbitrary mileagecredit (determined in some unspecified way).  The mileagecredit modifies the relationship between the frequentflier and the flight - it has no existence outside of that relationship.

In UML, such a class is shown as a dotted line off of the line connecting the two "main" associated classes.

(This is similar to bug 121725.)  

P.S.  I really like Umbrello.  Intuitive and immediately useful.
