I was on the road today driving my sons up to meet my dad for spring break. (We meet
half way which is Brainerd.) On the way up I was listening to a podcast that was talking
about SQLite.

It is an Open Source/Public Domain database. It is a flat file based system. It is
not going to scale out to thousands of concurrent users but that is not the point
of the project. I see some real potential for something like this. It is on my list
of things to investigate when time permits.

The list of companies that
are using this tool is pretty impressive.

I would like to investigate using it for Ruby on Rails, ASP/ASP.NET, and some other
projects that are tied to weather systems and embedded systems. Like I said, lots
of options and the price is right.
