Problems solved by technology
If only the record information is modified, the data entities will also be uploaded to the synchronization server during data synchronization, resulting in waste of user traffic and increasing the load pressure on the synchronization server
In addition, because the data record information and data entity are synchronized as a whole, if each user uses different record information, the data entity will be transmitted repeatedly due to the difference in record information during data synchronization, resulting in a large number of Data redundancy files occupy a large number of disks of the synchronization server and are not convenient for the management of synchronization data

Embodiment 1
[0104] In this embodiment, client A is used to synchronize data as an example. In this embodiment, the personal identity identifier (PID) is used as the user identity information, the SID is used as the data server identifier, and the CID is used as the data client identifier. , and the mapping relationship of CID to perform user data synchronization processing, that is, establish the mapping relationship of PID, SID, and CID, use CID as a keyword to query and obtain the client synchronization information of user-synchronized data, and use SID as a keyword to query and obtain Synchronization server synchronization information for user synchronization data.
[0105] In this embodiment, the various units and modules of the present invention are distributed and connected in the data synchronization system, the determination unit is set on the synchronization server to determine whether only the record information of the synchronization data is synchronized, and the synchronization r...

The invention discloses a method for achieving data synchronization and a system for achieving the data synchronization. The method comprises determining whether only synchronizes record information of data according the a synchronization request of the data when the data synchronization needs to be performed; updating stored record information in synchronization information of the data according to the synchronization request when the record information of the data is only synchronized; when record information of the data and a data entity need to be synchronized, after the record information of the data are newly increased to the synchronization information, according to a file verification value of the data entity, determining whether to upload the data entity so as to achieve synchronization of the data entity. The synchronization request of the data comprises the record information of the data and the file verification value. The method determines whether to perform the synchronization only on the record information and whether to perform uploading of the data entity through a judgment, a data flow while the data synchronization is reduced, and data redundancy caused by repeated storage brought by the data synchronization is prevented.
Description
technical field [0001] The invention relates to information synchronization technology, in particular to a method and system for realizing data synchronization. Background technique [0002] With the development of wireless communication technology and market, the widespread popularization of terminal intelligence has opened the prelude to the era of mobile Internet. People will rely more on mobile terminals, such as smart phones, tablet computers, electronic paper books, etc. to connect to the Internet to obtain information. Different from the Internet era represented by PCs, the mobile Internet era will present a trend of diversification of terminals and platforms. While bringing convenience to users, the mobile Internet introduces the problem of data fusion between multiple devices. In order to realize the consistency of data (such as picture, video, audio, etc.) between devices, data synchronization technology emerges as the times require. [0003] At present, manufac...
