Embodiment Construction

[0043] In one embodiment, such as figure 1 As shown, a data synchronization method is provided, including:

[0044] Step S110, compare whether the terminal data ID stored in the terminal is the same as the cloud data ID stored in the cloud server, if not, go to step S120, otherwise go to step S130.

[0045] Specifically, the data identifier is used to uniquely identify data, and the format of the data identifier can be customized. When new data is added, a data identifier is generated and correspondingly stored. The cloud data identifier stored in the cloud server is uploaded by the terminal to the cloud server. Because there may be multiple terminals, and the first terminal uploads the terminal data ID to the cloud server, the cloud data ID stored in the cloud server is the terminal data ID uploaded by the first terminal. terminal data identifier, the cloud data identifier stored in the cloud server will be different from the terminal data identifier of the second terminal....

Abstract

The invention relates to a method for data synchronization, which comprises the steps of comparing a terminal data identifier stored by a terminal with a cloud data identifier stored by a cloud server, synchronizing data according to difference between the terminal data identifier and the cloud data identifier if the terminal data identifier is different from the cloud data identifier, and setting a modification flag bit stored by the terminal to be a first preset value after the data is synchronized; comparing a terminal version identification string stored by the terminal with a cloud version identification string stored by the cloud server if the terminal data identifier is identical to the cloud data identifier, synchronizing the data according to a modification flag bit stored by the terminal if the terminal version identification string is different from the cloud version identification string, and setting the modification flag bit stored by the terminal to be a first preset value after the data is synchronized; and carrying out no processing if the terminal version identification string is identical to the cloud version identification string. Data synchronization can be carried out efficiently through matching of the data identifiers, the version identification strings and the modification flag bit stored by the terminal. In addition, the invention further provides a system for data synchronization.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data synchronization method and system. Background technique [0002] With the development of computer network technology, people use various network applications for work and study, and edit and use the same business data through different terminals (such as notebooks, ipads, smart phones, etc.). In order to ensure the synchronization of data modified by different terminals in the existing business operating system, the edited data is uploaded to the server for management in real time and can only be edited when connected to the Internet. [0003] If the business data is edited when the network is disconnected, it is necessary to ensure that the data edited by each terminal is synchronized when the network is connected again, so that different terminals can use the same business data. Contents of the invention [0004] Based on this, it is necessary to provide a data sync...
