Good effort. And I like the minimal documentation.
However, and I would love to be proved wrong, I think you are about 20 years late for this project to get any interest aside from some effimerous moments in hackernews...
No worries. It's just a write-up for what gets used in football.db, beer.db, world.db, etc. day in, day out. Also remember - as the say it's never too late :-).
