Data cascade synchronization system and method

Abstract

The invention discloses a data cascade synchronization system and method.The system comprises a database synchronization module, a message queue and an inter-stage synchronization module, operation of a synchronization source system database is captured by the database synchronization module and sent to a specified theme of the message queue, and the inter-stage synchronization module obtains database operation from the message queue, analyzes data contained in the operation, distributes the data to be synchronized to different destination systems in different themes of a message queue, acquires database operation synchronized to the inter-stage synchronization module from a specific theme of the message queue by the inter-stage synchronization module of the synchronization destination system, and writes the database operation into a database of the system; The data which do not need to be synchronized can be discarded according to service requirements, and the data which need to be synchronized are distributed to different synchronization target systems according to configuration.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data cascade synchronization system and method. Background technique [0002] If traditional information systems involve multi-level organizations, centralized deployment is generally adopted, that is, a system is deployed in the top-level organization to provide services for all organizations. In this deployment mode, if the network of the upper-level organization is disconnected from the network of the lower-level organization, the lower-level organization will not be able to use the services provided by the information system deployed in the upper-level organization. In order to meet the requirement of not affecting the use in the event of a network disconnection, the system needs to be deployed hierarchically, that is, a set of information systems are deployed in institutions that need to ensure availability, and data synchronization with the superior system is perf...

AI Technical Summary

Problems solved by technology

The current existing data synchronization technologies are full data synchronization. The use of these synchronization technologies will cause the upper-level system to synchronize the data that does not belong to the lower-level system and the data that needs to be synchronized. Lower-level systems, on the one hand, cause a waste of network bandwidth, and on the other hand, cause data leakage
