Application-independent data synchronization technique
A method, system, and computer program product for automatically synchronizing data between a replicated version and a back-end data store version which may or may not have the same format. Queues are used for scheduling refreshes of read-access objects and updates of write-access objects, where the actual processing will occur when the client device connects to the back-end data source. This technique is application-independent, and does not require writing application-specific code to perform a synchronization between data stores having dissimilar storage formats. This technique is particularly advantageous for mobile computing devices, which may operate primarily in a disconnected mode, and for distributed branch-office computing environments where a local server has a replicated copy of data stored at a back-end enterprise system. This technique is also advantageous where the back-end data source uses legacy host application or database storage formats, and where the client software uses modem object-oriented data storage formats. A technique is defined for offloading the processing to a remote machine.
