Uses Of Databases
In GPS System:
We need to map the
database of locations collected in it and then we need to check the
information which is collected from antenna and sensors. That
information will be again mapped with database and will provide
results on display of the car with the help of its car navigation
system. Sensors used in the devices are direction and speed sensor.
The mapping database is accessed with the help of SD card, HDD, DVD
and CD ROM. In autoradio gps ford kuga, the car navigation
system will be using four different databases in order to decide
route for the driver by calculating distance between current location
of the car and direction of the car. Those databases that are used
for this process are: road network data, voice data, site information
data, and background data. The background data contains information
about rivers, railroads, and contours. The site information contains
information like name of the building and its addresses.
