Abstract

The invention provides a data synchronizing method. The method comprises the following steps of acquiring first data to be synchronized; based on data serial number and data feature information, judging whether data information which contains at least one of the data serial number and the data feature information and is different from any data information in the other one of the first data and second data exists in the first data and the second data or not; and when different data information exists in the first data and the second data, sending the judged different data information to a server, so that the corresponding data in the server is synchronously updated to acquire third data after current synchronization. The goal that a synchronizing client can also accurately find the data required to be synchronized under the condition of no data operation log is achieved. The method has the characteristics of high speed, real-time property, high efficiency and applicability. The invention also discloses a data synchronizing device and a data synchronizing system.

Description

technical field [0001] The invention relates to the technical field of communication information, in particular to a data synchronization method, device and system. Background technique [0002] At present, log management is used to identify which data needs to be synchronized, and the operation on the same data does not have the function of merging, which will lead to many unnecessary operations and cause inefficiency of system data. [0003] Specifically, for clients that need synchronization, most of them are mobile phones, and the processing capabilities of mobile phones, whether it is mobile phone memory, mobile phone IO, etc., are relatively general. In the management mode, each operation records the corresponding log management, which will cause a relatively large burden on the client system. The user's mobile phone runs slowly, consumes a lot of power, and responds slowly, making it difficult for users to accept. At the same time, due to the client record Every oper...
