Once again I have been working with SQLite within Adobe AIR. I use a couple of database visualisation tools to access the database, both of which are a little bit like TOAD (for those of you who remember that far back).
Lita, is a standalone AIR application.
SQLite Manager is a Firefox plugin.
The benefit of the Lita application is that you can launch it from your OS, wheras the SQLite Manager you have to launch from Firefox’s tools menu. I usually prefer using Lita as I find that using SQLite Manager interferes with my browser usage; however, when I want a second opinion on a database file or want that little bit of extra functionality, I use SQLite Manager.
