I guess you are right, but there are a lot of related tables. I wouldn't
call it simple, though. It can get huge, however.

I'm not sure what a Garmin GPS unit is, but the TigerUA DB uses longitude
and latitude. Any reasonable geographical system must somehow map to lat/long.

Actually, I am going to download the latest version and get it installed on
