Software to tag, rate photos?

[aceO07]

I've had my DSLR for a few years now and I've finally decided I may want to tag, rate them. Currently I have each session/trip in its own folder. I'd like the ability to tag each photo with keywords or description, and also to rate each photo. I do NOT want any of this data embedded inside the photos, but rather in a database. I want to preserve the files the way they are.

I'd definitely prefer free software if that's possible.

I don't know what brand name of your DSLR but I have used Canon ZoomBrowser EX that can do tag, star rating, keywords and description. It comes free with my Canon Powershot.
