Inverse fk lookup

[Peter Costa]

Is is possible to a inverse foreign key look on a reference descriptor.
I have a dealer(Parent) table and a dealerPreference (child)table where
the dealerid is the fk on the dealerPreference table. I want to set it
up so that when I get a dealer object I automatically get a
dealerPreference object. What would be the best way of going about this?
