Need for Mobile Database
1) Mobile users must be able to work without a wireless connection due to poor or even non-existent connections.
2) Applications must provide significant interactivity.
3) Applications must be able to access local device/vehicle hardware, such as printers, bar code scanners, or GPS units (for mapping or Automatic Vehicle Location systems).
4) Bandwidth must be conserved (a common requirement on wireless networks that charge per megabyte or data transferred).
5) Users don't require access to truly live data, only recently modified data.
6) Limited life of power supply(battery)
7) The changing topology of the network
If your application meets any of those requirements, the chances are good that you will be required to build a mobile database application with synchronization.
