It is useful to represent the pieces in Pd space, so you can  
understand what's going on.  That's one reason why I advocate having  
the core object represent the connection to the database rather than  
a query.  Otherwise, it's starts to become more like Max/MSP's mega- 
objects (coll, zl, etc) that are really like mini-applications than  

There still can be query objects, they would just be designed to feed  
to the core database objects.  These query objects would then be  
usable if we maintain the same interface.
