Not really clear what you are trying to accomplish. The simple fact
that all 3 workstations are communicating with a central database means
that they all "get the changes". Are you saying that B and C might be
displaying the old version of data that A has just changed, and you want
B and C to automatically see the updated values? If that is what you
are after, then you'll need to do something application-wise. What
application are these clients using to view data? You can either (1)
broadcast changes entirely through your application, or (2) set up a
trigger in the database to kick off the notifications. Depending on how
many changes you want to monitor, solution 2 might be burdensome (lots
of triggers.)
