I am working on an application that will cross from the Web
to an office network to occasionally connected laptops. I've chosen
Flex & AIR because it easily works in all environments without
me having different applications for each scenario. What I'm
struggling with is the DB to use, particularly on the laptops.
These laptops will need to interact with a local copy of the
database, then have that sync back up with the "master" when
connected. MySQL 5.1+ seems to accomplish this, but I have concerns
running PHP, WebORB, and MySQL on every laptop. That's a lot to
keep running smoothly. Is there a better approach to this?
