Once you get into databases, platform independence will be an issue. There are many databases out there to pick from. If you want something which will work on a lot of platforms, a reasonable place to start looking is MySQL. It's free, runs on lots of platforms, has good Python support, and there's lots of people on the net who know it and are willing to give help and advice. Databases have a bit of a learning curve. If you've never done any database work, don't expect to download MySql (or any other database) this afternoon and be up and running by tomorrow. Whatever database you pick, you're almost certainly going to end up having to install it wherever you install your application. There's no such thing as a universally available database that you can expect to be available everywhere. Have fun! -- http://mail.python.org/mailman/listinfo/python-list
