Introduction
Software should be generic off the shelve packages, easy to program, and easy to use.
All hardware should be
chosen according to the availability of services and supplies at local level.
Inexpensive PC’s, locally trained operators, and local “maintenance” will be
suitable in all levels of use.

Client/Server
for local clinics
The system will be infinitely
malleable. It is easy to run the client and server portion of an application on
the same machine and does some occasional communications with outside servers to
exchange data, refresh a database, and send or receive mail and faxes.
Client/server for
District and Departments
Well-suited for the LAN-based
single server establishments. It
consists of multiple clients talking to a local server. May use the server to
interact in a very loosely-coupled way with some enterprise server. For example,
data (medical information for the day) may be downloaded once a day to refresh
the local server. Or inventory data may be uploaded to an enterprise server. Fax
and mail can be sent or received any time through the mail server gateway. These
departmental servers will continue to be popular, even in large enterprises,
because they provide a tremendous amount of user autonomy and controls. Users
feel that it is their server, and they can do anything they please with it.
Client/server
for Intergalactic enterprises
It
is upwardly scalable. When more processing power is needed for various
functions, more servers can be added. We can partition servers based on the
function they provide, the resource they control, or the database they own. In
addition, we may choose to replicate servers for fault tolerance or to boost an
application’s performance.
The
system is modular in the sense that it would be able to grow with the size and
demands of the health system. The data may be accessed through a network that
would include both local and national connectivity.
