Hi Carlos !

A known issue occurring from time to time.

Again, let's remind ourselves that we are trying to
encapsulate *business* objects. Tables, however, do not
correspond to business objects 1:1 because they are fairly
normalized. Thus a business object can span several tables
hence we need to keep track of several primary keys within
one such object.

Sure. For all business objects inheriting from clin_root_item
this could also be centralized.

Right on !

Exactly.

It's really quite simple: Ultimately we want to be able to
produce a patient printout, hand it to a random fellow doctor
and have her comprehend the information without any assumed
knowledge about GnuMed.
