Problems solved by technology

[0004] However, due to the complex and changeable data processing of the existing business, the amount of data to be processed is also increasing rapidly. Using the existing synchronization method, a large amount of data needs to be backed up before synchronization, thus occupying a large amount of memory. Compared with the backup Excessive system consumption will also be generated during the process of forming synchronous data from previous and subsequent data
Moreover, in the process of collecting data before and after backup by the data synchronization mark set, data errors are prone to occur, so the accuracy and consistency of data synchronization are difficult to guarantee
Thus, the existing data synchronization methods have affected the processing speed and system performance of the entire synchronization system

Abstract

The invention discloses a data synchronization method, device and system. The data synchronization method comprises the steps of: before submitting a transaction, obtaining a unique identification of the current transaction; according to the obtained unique identification, inquiring cancel information of the current transaction; analyzing the inquired cancel information, generating synchronization data information, recording the synchronization data information in a synchronization data interface table; and transmitting the synchronization data interface table to a device to be synchronized. The data synchronization method, device and system provided by the invention have the advantages of automatically collecting synchronization data, reducing system complexity, improving data collection accuracy rate, increasing system processing speed, enabling the system to be easily maintained, and realizing modularized data synchronization.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data synchronization method, device and system. Background technique [0002] With the continuous and rapid development of the Internet and the widespread popularization of personal computers, the operation of the database is becoming more and more complicated, and people's requirements for information sharing are also getting higher and higher, which makes the data synchronization problem become a hot issue. [0003] The prior art generally adopts the following method: when there is a business to be processed, the data synchronization flag set set according to the business type backs up the corresponding data table, and each bit in the data synchronization flag set represents a different data that needs to be synchronized. Data table; after business processing, obtain the latest data table according to the data synchronization flag set, and compare the current latest data table with t...
