Data "over time" is not stored in the TD database. Actually, the only things stored in the database are players and player information (personal data like name, address, phone, email, etc), seasons, and leagues and their membership lists.
The TD generates Stats (which amounts to data "over time") on the fly by reading your tournament files. There's no way to extract this, except in an export of data from the Stats tab.
If Stats Genie stores data in a database (which I suspect it does), you're probably better off trying to glean data from there.
