Abstract

The invention discloses a data synchronization method and system and a storage medium, the system comprises a main database, a database trigger, a synchronization queue and at least one client database, a plurality of synchronization data are stored in the main database, and the synchronization queue is provided with database tables corresponding to the synchronization data; wherein the database trigger is used for monitoring a main database, triggering to generate trigger information when a synchronous data sending event operation of the main database is monitored, and sending the trigger information to a corresponding database table; wherein the synchronization queue is used for acquiring synchronization data from the main database in combination with the trigger information and the database table, and performing synchronization operation on the client database according to the acquired synchronization data. Synchronization is carried out in a monitoring and queue synchronizing mode,namely data synchronization is carried out on the basis of a database layer, performance is high, fault tolerance is good, data can be prevented from being lost in data synchronization, and the method can be widely applied to the technical field of data synchronization.

Description

Technical field

[0001] The present invention relates to the field of data synchronization technology, in particular to a data synchronization method, system and storage medium. Background technique

[0002] At present, government departments at all levels have built or vertically built many government affairs applications. In some cases, some departments need to share the government affairs data of other departments. For example, the supervision platform of the disciplinary committee needs to supervise the government affairs service efficiency of each department and needs to extract the business data of each department. For analysis and judgment, it is necessary to synchronize the business data of various departments to the supervision platform of the Commission for Discipline Inspection. At present, the commonly used data synchronization solutions in the market have the problem of losing data after synchronization failure, or the problem of unstable synchronization after a long p...
