Introduction
This technical note discusses how to
determine
the number of licenses needed for Client/Server installations and the
approximate
cost.

Discussion
The number of users that access the server
at
any one time is referred to as the number of "concurrent" users.
The server manages or limits the number of concurrent users based on
the
licenses purchased for both the server engine and the
application.
The following examples illustrates typical client/server
installations.
Example 1: Installation for 2
concurrent users
(Basic "2" user license)
This will allow two users to access the
database
system concurrently from any of the PCs (or Macs) within the office.
Single physician office
(1) Physician (part to full time)
(1) Receptionist (full time for
registration
& billing)
---
(2) Total number of concurrent users (2
computer
stations)
Hardware:
(1) Server (Windows 2000 or XP)
or
(Macintosh acting as server)
(2) Computer stations (PC or Macintosh)
Software: ($US 2,898)

Installation:
Server hardware would have Med-Center
Server
Application installed.
Computer stations would have Med-Center
Client
installed
(Note: SuperReport Pro is optional
but useful
for user customizable reports that include invoice & fee ticket)
Example 2: Installation for 8 concurrent
users
(Basic "5" user license plus expansion packs)
This will allow 8 people to access the
database
system concurrently from any of the PCs (or Macs) within the office.
Multiple physician office
(5) Physicians (part to full time)
(2) Receptionists (full time for
registration)
(1) Billing (full time)

installed
Computer stations would have Med-Center
Client
installed
Example 3: Installation for 28
concurrent users
(Basic "20+" user license plus expansion packs)
This will allow 28 people to access the
database
system concurrently from any of the PCs (or Macs) within the office.
Clinic
(16) Physicians (full time)
(5) Physicians (part time use only)
(3) Receptionists (full time for
registration)
(4) Nurse stations (full time for patient
reference
and charting)
(2) Billing (full time)
(1) Billing (part time)
--------------------------------------
(25)+(6 "part time" times 50%) =
(28 "full
time") Total number of concurrent users (28 computer stations)
Hardware:
(1) Server (Windows 2000 or XP)
or
(Macintosh acting as server)
(28) Computer stations (PC or Macintosh)

installed
Note: Special reduced pricing may apply
for large group licensing of 4D Server.
Summary
The number of concurrent users needed
depends
on the office size and planned usage of the client / server
system.
