Abstract

The invention discloses a data synchronization method and device. The method comprises the steps of reading a catalogue index file in a first data source, thereby obtaining data catalogues of n applications contained in the catalogue index file; reading a data index file Ei contained in the data catalogue Di; resolving an update configuration file of the application Ai, thereby obtaining catalogues of target data and a type attribute of the target data in the application Ai, wherein the target data is the data on which data synchronization needs to be carried out; and converting a data structure of the data in the first data source according to the change information in the data index file Ei and the type attribute of the target data, wherein a second data source obtains the data after the data structure is converted in the first data source, thereby finishing data synchronization. According to the method and the device, the technical problem that in the prior art, the synchronization performance of the data between different databases is relatively low due to the fact that a user cannot screen the data needing to be synchronized according to the demand of the user is solved.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data synchronization method and device. Background technique [0002] In the prior art, there are mainly three data synchronization methods, as follows: [0003] Method 1: Synchronize the data of its own multiple databases based on the built-in method of the database service. [0004] For the above data synchronization methods, only some databases have their own data synchronization functions, so the choice of databases is limited, and it is more suitable for a single fixed product. Users cannot filter the data to be synchronized according to their needs, resulting in different databases. The performance of data synchronization is poor. Moreover, each deployment project needs to be deployed separately, which increases the complexity of deployment, and different databases are configured in different ways, which increases deployment costs. [0005] Method 2: Data synchro...
