See Joe Kampschmidt's guide to football data and APIs [1] - that's
the best (most extensive / detailed ) write-up about the
"state-of-art".
About the football.db - nothings happens unless you do it e.g.
you're welcome to join and contribute (instead of looking how you can
serve yourself as is the general practice).
Cheers.
