These programs can fonction within a network.

Several computers linked togrether in a network (Local area network Microsoft Windows for instance) can communicate together using one single database on a central computer (server). These programs have been designed as front end back end applications seperating user forms and reports from the actual data.

This architecture let you manipulate data together with several other users at the same time.

UTP cable :

In a network the database distributes data in real time to all computers : as soon as one user changes data on a form other users with the same form on their screen will see those changes immediatly. Understanding the enormous amount of data going through the cable, you should not implement this kind of networking over the internet (Virtual Private Networking) and hope for speed. With a local Wifi it can fonction, but speed will nevertheless suffer.
