Bento is a personal database application for the rest of us (Mac users running Leopard). There's a free demo at FileMaker's website.
As I said, Bento requires Leopard. There's not a lot of information about Bento on FileMaker's site, but it does list a couple of Apple's "iApps" that it works with as well as the Address Book application.
I hope it spits out HTML, that would make it really useful.
Check it out.
