Problems solved by technology

[0005] In the prior art, the above two measures taken for data synchronization failure, the prior art actually fails to provide remedial measures for the data synchronization failure situation, such as for the first measure, the real-time synchronization center is only for the failed synchronization However, in fact, the data maintained in the source business and the target business are not the same, that is, the data on the source business and the target business are not synchronized; the essence of the second measure is not to accept data change operations, and all The data update on the business fails, so although the data on the source business and the target business can be kept in sync, if the data change request comes from the user, the data change will fail, which will cause trouble to the user
[0006] Therefore, data synchronization failure is prone to occur in the data synchronization scheme of the prior art

Embodiment Construction

[0023] The technical solutions of the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0024] In the embodiment of the present invention, a further data synchronization operation is performed on the data that has not been successfully synchronized by the real-time synchronization center, so as to ensure that the data synchronization between services can be successfully executed as much as possible.

[0025] Firstly, the synchronous processing of data on various services by the real-time synchronization center in the embodiment of the present invention will be described. For convenience, assume that there are three global services, recorded as: business 0, business 1, and business 2, and set the modified data item as user nickname. Referring to Fig. 1, Fig. 1 is the flow chart of synchronizing data among each business of real-time synchronization center in the embodiment of the present invention, and...

Abstract

The invention embodiment provides a data synchronization method which comprises data update records that the data synchronization center obtains from each operation and the corresponding marks for successful update of operational data items in each data update record. The method includes the following steps: the data synchronization center inter-compares each update record to find out the data item that only is contained by some operation data update records and not by other operations; the other operations are objective operations; the data synchronization center sends a notification of updating the content of the data item to the objective operations, wherein the notification carries the updated data content of the data item obtained by the data synchronization; the objective operations update the saved data content of the data item after receiving the notification. The invention embodiment further provides a synchronization device. The technical proposal of the invention embodiment can as far as possible guarantee the data content synchronization of the data item which needs to be maintained synchronization by each operation.

Description

technical field [0001] The present invention relates to the technical field of data synchronization, in particular to a data synchronization method and device. Background technique [0002] Different businesses usually maintain some of the same data. If the data in one business changes, the data maintained in other businesses also needs to be changed accordingly to keep the data in different businesses the same, that is, to keep the data in different businesses Synchronization of related data maintained on the [0003] In the prior art, by establishing a real-time synchronization center, the synchronization of the data that needs to be synchronized maintained on different services is controlled, that is, the global data synchronization. Initiate a data update request, that is, notify the synchronization center that the data needs to be updated, and inform the updated data; then, the real-time synchronization center notifies other related businesses to update the data to mai...
