Standard Database Information
It would be more economical if you would have standard database information such as:
Standard
Country, City, State, Zip Data
Spell Checker
Time Zones
Offbeat
Other databases that users can submit such as
Radio Stations, RNA,DNA sequences, Movies
Calorie Counters etc.
These databases would be read only but they would save from everbody having to have their own data source on your servers....
