I want to make a 'application' that operates through a browser. It should be offline / local on the users machine. It needs a database to store and retrieve data. And - because it should be really easy to use - it should run without a server.
The only thing I found so far is the Google Gears API: http://code.google.com/apis/gears/ but I don't really know if it's ideal for my purposes, because the database will contain quite some data and it should be easy to backup.
Any ideas, suggestions?
Thanks!
