Hi Friends.
Presently I am working on GPS Application. I have to create a database in which I can keep coordinates in terms Of Latitude and Longitude.
In that data base I have to give start location and end location in a query and it will return the series of Lat/Long which shows the path.

Please guide me what should be the design of that database.

Thanks In Advance
Pankaj
