I should have been more clear in my question. I am more interested in what
you mean by the terms "tight coupling" and "poor cohesion". I am aware of
most of these specific problems in Vista (except for the the Lab one). I am
becoming more and more aware of the tangled mess in some of the RPC calls in
the OR* namespace. I assume that amounts to tight coupling. I doubt I
would know what poor or good cohesion was when I saw it. I do know when the
code is hard to read.

Subject: Re: [Hardhats-members] Data dictionary question...
It is certainly true that the infrastructure packages (Kernel, Fileman,
etc.) do a good job of reducing the degree of coupling in Vista (part of
its genius, IMO) but pick your favorite application. How easy it to
rework it to use a different approach? How many Vista applications still
use HL7 1.5 (notably Lab) because it's not practical to move over to 1.6?
Why are people so interested in using Imaging to store scanned documents
(something having absolutely nothing to do with medical imagining)? Why
has it taken so much effort to figure out how to add new patients to a
Vista system when it is not being used in a VA setting? Why is it so hard
to adapt IB/ AR to the needs of non-VA users of Vista? Why is re-indexing
file 2 such a case of "shoot self in foot"? Why did identifying and
resolving duplicates in this file require such a herculean effort?
