Why how precious. Plonked.

I've now been plonked by two people in this newsgroup. Whoohooo!!
I gotta be honest, I couldn't see the relevance of you response to the
OP's question. Roy's and Adrian's responses were good pointers, while
the general warning away from EAV by everyone else was also apt. I'm
not sure how your personal anecdote contributed to his trying to
reference multiple relations from the same foreign key.

To the OP - have you considered just using different tables for the
attachments? Sure attachments are all of the same type but relations
don't collectivize objects (a common misconception that has to be
shaken off when moving from OO to RM). Relations collectivize
propositions of a common form - and yours seem to be different.
