Abstract
A method for synchronizing the data between two separate computer systems is described. In a first aspect of the invention, the method includes the step of identifying each record stored in the memory of the first computer system that is intended to be synchronized. The records are identified with a unique identification indicia and an indicia that indicates the last time that the record was altered. Using the time of the last synchronization information, each of the selected records that was added to or deleted from one of the computer systems since the last synchronization is identified and added to or deleted from the other computer system. Further, each of the records that was modified on one computer system is modified on the other. If conflicting actions have occurred on the two computer systems, then the conflicts are handled in accordance with a predetermined protocol. In a preferred aspect, a synchronization list is created that identifies each of these additions, deletions and modifications and either prioritizes them in accordance with the protocol or informs the user of the conflicts.
