[Dbix-class] Relationship question/database structure

[Steve]

Hi All,

I'm trying to use an existing schema wherein I have a generic table 
called 'Note' containing - you guessed it, notes!.  The thing is that 
these notes may be associated with many other types of data and 
therefore tables in my database.  They may be related to a request, 
user, device, etc.  I am sure that this is a fairly common use case, but 
don't see much in the docs or on the list.

The question is two-fold: What's the best structure, and how do we go 
about defining the DBIC rels?
Thanks,
Steve
