Problems solved by technology

[0002] At present, government departments at all levels have self-built or vertically built many government affairs applications. In some cases, some departments need to share government affairs data of other departments. For analysis and judgment, it is necessary to synchronize the business data of each department to the supervision platform of the Commission for Discipline Inspection. Currently, the commonly used data synchronization solutions in the market all have the problem of data loss after synchronization failure, or the problem of unstable synchronization due to long-term failure to synchronize

specific Embodiment 1

[0058] The following combination image 3 The above method is explained in detail.

[0059] A data synchronization method includes the following steps:

[0060] Step 101: The main database event is triggered externally, which can be through the system application operating data or directly triggering the event in the database.

[0061] Step 102: After the trigger listens to the main database operation event, it inserts a piece of data into the synchronous queue library according to the event type. The data includes the data primary key value of the event, the self-increment sequence (queue primary key), and the event (addition, deletion, modification) , Status (to be synchronized, abnormal), trigger event identification (insert, update, delete).

[0062] Step 103: The synchronization program cyclically reads the primary key of the data waiting to be synchronized from the queue library, then finds the data in the table with the same name in the main database, and then writes it to the ...

specific Embodiment 2

[0067] The following combination Figure 4 The above system is explained in detail.

[0068] A data synchronization system includes a main database, a database trigger, a data configuration program to be synchronized, a trigger generation program, a synchronization queue, a synchronization program and at least one client database. The system can realize data synchronization configuration flexibly and quickly, and is compatible with most popular databases in the market.

[0069] The data configuration program to be synchronized is configured by the program to configure the database table names and synchronization conditions that need to be synchronized. The trigger generation program needs to configure the main database connection and the synchronization queue connection. After the program is started, the synchronization trigger is generated according to the database table name and synchronization conditions configured by the data configuration program to be synchronized. At the sa...

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...
