Health Information Architecture
http://www.va.gov/vha-ita/ita-p.html
The Architecture provides a technical framework to promote one technology vision across the VHA so that corporate systems and systems across VISNs are interoperable. The framework is designed to be flexible, and is updated as new needs are identified.

I have given this issue a fairly extensive treatment in an IT architecture document I prepared some years ago for the DVA. That paper was reviewed by VistA IT architects during its development. Some on this list may have copies on hand. The paper is a serious read, and not to be considered a 'one-pass' discussion. The document is imperfect, and could benefit greatly from a second, major edition. Even so, it does answer your question and expands substantially on what I have been saying here lately. If you really want to invest the time and energy, perhaps that document can be located for you.

Today, the core database within VistA does not contain a generalized "business-rule" engine as a centralized, high level, tabled driven module that controls all data storage and retrieval. Classical DHCP applications and the VistA modules of today are obliged to embed their business rules in M(UMPS) routines where they are extremely difficult to manage.
No amount of "open" design in DHCP/VistA can overcome this shortcoming of
the missing business rule engine.
Please give more description and some examples of what you think is missing and how it might be added.
