Hey. If your anything like me you like RDMS (SQL databases); but you don't like the thought of making people install mySQL with your mirc script.
As a PHP developer, its been paraded up and down infront of me a lot, and I finally took a look. I'm talking about SQLite.

Its a pretty good little command line application that comes in at a measely 129kb - yet provides about the same functionality as mySQL for smaller databases. This means its perfect for mirc. It gets better too. You can either interact via the command line (dlls in mirc exist for this) or you can get SQLitePlus which includes a COM object, usable right from mirc.

Just thought I'd let you know, as I *hate* using unwieldy hash tables and trying to do some of the whacky things I can do with SQL.
