Oddly enough, I do this already, though the data comes from my raw logs (which I dump into an off-line Access database) and run several relational tables against it... one of which is "linkfrom" which contains links to the site AND the first date added to the table. I can then do date calcs, etc... which also alerts me when I HAVEN'T had activity from a known link after 60 days... reminds me to check on that link to see if it still exists.
Use whatever database you like, but you will start with your raw log first, then build out by whatever criteria for your sub-tables (all unique) to do your reporting.
One value is knowing who is linking and HOW LONG IT TAKES G or B or Y to find it, too. But in the long run unless that link is in the big SEs the only value you'll get is learning wehre word of mouth has spread your fame, or your link building success, or how rapidly the scrapers have found YOU.
