1. A method of synchronizing data records stored in a host system and a device system, comprising the steps of:

  • associating a first device synchronization parameter and a first host synchronization parameter with a data record stored at the host system;

    associating a second device synchronization parameter and a second host synchronization parameter with a data record stored at the device system;

    updating the first host synchronization parameter when the data record is updated at the host system and transmitting a first update message from the host system to the device system; and

    updating the second device synchronization parameter when the data record is updated at the device system and transmitting a second update message from the device system to the host system;

    wherein the first and second host synchronization parameters are indicative of versions of data records stored at the host system, and the first and second device synchronization parameters are indicative of versions of records store at the device system.
