Switching to local database to a PostGreSQL DB on server

Dear friends, hello!

Soooo ... I have a question ...
I am using SDL Business Manager on my laptop, it means on local ... Maybe, what I wanna do is, buy a second license to make my assistan work on it and move my local DB on a web-stored PostGreSQL DB ...

This is a new idea. I just started to think about this but I already have a server and what I need is basically only build a new postgre DB there and upload there the dump of my local DB ...My question is ... is there any fixed and already tested procedure to do this? Is there any feature SDL BM have already in it? Does it make sense? ...

In this case, a laptop with this on-line DB ... will be able to work OFFLINE ???
And if so ............ how will the syncronization be made then?
Manually? Or what?
Alternatives?

Thank You!
Pietro
