Re: Help with data transfer please

Hi!
You're sure right about that! However, what do you
think about using triggers on update and insert from
two different machines, and then at night using cron
(rh linux) to call the other machine and
transfer/update only the records that have changed?

Although at this time the database only needs to be
active where I am, there will be about five other
people actively inputing/getting data from the server.

Initially, I was headed toward your second
proposal-until a quick calculation of the telephone
costs put it out of reach. Unfortunately, only one
office has decent internet connections other then by
phone line.

Thanks!
