I am not that clever, but I would just create a Web Service (WS) on the
Server that the Laptop call whenever the laptop want to push the date into
the server database.
I heard something about something called rsync, but I think that is
restricted to Linx, Unix.

Subject: UPDATE from one server to another
I am working on an application where data will be collected on laptops
and then uploaded to a central database once the laptop is able to
connect to the network after being in the field. I was initially
thinking of using MS Access as a front end with linked tables through
MySQL ODBC. I am now considering running WAMP on each machine with a
web interface because there will be no interoperability issues if MySQL
is the db server on both ends, but I am 1.) looking for any
recommendations for the laptop interface (MS Access/WAMP or whatever
other options might be available) and 2.) want to know what is the
actual command for updating a table across two servers (this is NOT
replication, but merely updating new data to an existing table).
Data transfered will include binary objects and possibly GIS data.
For example, Laptop 1 might have 10 rows of data from todays activities
that need to be added to the main Server. Laptop 2 might have 30 rows
of data that need to be added to the main Server. Neither laptop needs
to have the data from the other, but the Server will contain data from
both Laptops at the end of the day. The Server will then offer the data
through a web interface.
MS Access 2003 OR
MySQL 5.0/ PHP 5/ Apache 2
