  • Resolving update-delete conflicts
    Patent number: 7769727
    Abstract: Update-delete conflicts detected during synchronization can be resolved in favor of the update or the deletion. Resolving the conflict in favor of the deletion results in the entity deleted on one replica being deleted on all selected replicas. Resolving the conflict in favor of the update results in the updated entity, which includes an entity moved from one hierarchy to another, being replicated on all selected replicas. To resolve the conflict in favor of the update, the deletion is treated as though it were reported erroneously. The deleted entity is resurrected in the form of the updated entity. Change version information is maintained in all replicas. Update-delete conflicts are resolvable in accordance with various resolution policies such as the update wins, deletion wins, changes occurring on a particular device wins, and most recent event wins, for example.
