How to autoupdate form contents whit multiuser env.

[Atlas]

Is there an effective way to autoupdate form contents when data changes on
the server in a multiuser environment, or do I have to stick with timers and
force form update at specified intervals?

Thanks

I've read a few articles about managing updates with the timer. But isn't
there a more effective way to do so?
Maybe logging updates...could be a table on the server containg updates and
let the forms read every n seconds this table to check if an update
occurred...or an intercommunication process....maybe broadcasting refresh
requests....fantasy?
