Embodiment Construction

[0066] The present application will be described in detail below in conjunction with the accompanying drawings, and the specific operation methods in the method embodiments can also be applied to the device embodiments.

[0067] figure 1 A system architecture diagram applicable to the embodiment of the present invention is shown as an example. Such as figure 1 As shown, the system 100 includes a management device 101, multiple source databases (such as figure 1 source database 1021, source database 1022, and source database 1023) and at least one data sink (such as figure 1 data sink 1031, data sink 1032, and data sink 1033 shown in ). Wherein, the management device 101 can be connected to any source database through a network, for example, the management device 101 can be connected to any source database in the source database 1021, the source database 1022 and the source database 1023 through the network; the management device 101 can be connected to any data sink It may...

Abstract

The invention discloses a data synchronization method and device. The method includes: after the management device receives the source data sent by the source databases in the current period, it calculates according to the association relationship between the source databases and the multiple data records included in each source data to obtain the target data set And send the target data set to each data sink. In the embodiment of the present invention, only the management device needs to perform this calculation process, and the calculation of the target data set is performed during the synchronization process, so that the data sink can directly obtain the target data set, which greatly reduces the calculation amount of the entire system and improves data synchronization. timeliness.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data synchronization method and device. Background technique [0002] Data synchronization has always been an inevitable problem in the interaction between computer systems, and the timeliness and accuracy of data synchronization will directly affect the interaction between computer systems. In the existing data synchronization technology, each source data in each source database is usually synchronized to the data sink first, and then the data sink performs calculations to obtain the required data. However, this method requires such a calculation process for each data sink, and the process is relatively complicated and time-consuming. [0003] Based on this, there is an urgent need for a data synchronization method to solve the problem that the data synchronization process in the prior art is relatively complicated and takes a long time. Contents of the invention ...
