Abstract:
1. A method comprising: receiving a request specifying synchronization of information records of a source dataset residing on a first device with information records of a target dataset residing on a second device; determining a synchronization set by: wherein each information record of the source dataset is assigned a globally unique identifier that is independent of either of the devices, for identifying said each information record at both the source dataset and the target dataset, said globally unique identifier being maintained in a device-independent record map that allows the globally unique identifier to be traced back to a specific information record regardless of whether the specific information record resides on the first or second device; and based on said synchronization set, synchronizing information records of the source dataset with information records of the target dataset by: wherein each of the globally unique identifiers comprises a non-modifiable hidden field containing a record identifier which is maintained throughout the existence of a corresponding information record.
