I don't know a lot about relational databases, but I'm a quick study. I installed MySQL once and played with it for a while - long enough to know I would love to develop some perl-SQL skills. I just didn't quite know where to go with the daemon and eventually uninstalled it because it was wasting resources. However, if I were to get started with something like this file search utility, I can foresee many other potential applications. Do you recommend SQLite over MySQL?
