Also commonly known as "sqlite3".
Working with Python and SQLAlchemy
For day to day stuff, I use Python and SQLAlchemy to talk to databases. Look for "SQLite Manager".
I also use the command line program, called "sqlite3".
You need to know about this
There is a plugin for Firefox that lets me dig around in sqlite databases. Once installed you access it under Tools->SQLite Manager and it lets you view schema and contents of a local sqlite file. If you create a database programmatically it is very handy to be able to check the schema turned out as you expected and to directly hack on the data in its tables.
Yaris app
I started writing an app that uses SQLite to track and map my Yaris MPGs. I was planning on putting it on my Garmin Monterra. Not doing any Android work right now though!
