We are developing an application for leather industry using PostgreSQL with
PHP scripting. The program will be run from a central server and buyers and
sellers will login using internet connection and update/exchange information
through the system.
Some companies do not want to be connected to the internet throughout the
day. They want to use the system from a local server during the day and
update the data to the central server (and get the updated data from the
server) once or twice a day.
Can someone please advise me, how this can be accomplished? That is, to make
the two databases hand shake and exchange the changes effected since they
last met.
Best regards,
