Data synchronization method for double-nucleus library

Abstract

The invention discloses a binuclear base data synchronization method, which is characterized in that the binuclear base comprises a data bin and a foreground application lib, the binuclear stores the data accessed by a business analysis system user in the data bin and stores a backup in the foreground application lib, when the business analysis system user accesses, the invention uses multilayer mechanism that when the access of the foreground application lib fails, the business analysis system automatically switches to access the data bin, the data between the data bin and the foreground application lib according to self periodicity to realize real-time synchronization via a synchronization system. The invention realizes a plurality of periodicities of synchronization as timed synchronization, circulating synchronization or trigger synchronization, which can be managed according to missions to manage the data demanding synchronization, eliminate the system resource consumption caused by database self-synchronization mechanism and make detection on the synchronization easy. Each synchronization process can be repeated without effect on result. The invention can manually start one synchronization process, besides automatic synchronization operation.

Description

technical field [0001] The invention relates to the technical field of computer databases, in particular to a dual-core database data synchronization method. Background technique [0002] At present, the communication industry, especially the business analysis system used by operators (a unified data information platform for enterprise operations, provides effective support for the entire network business, customer service, marketing, business decision-making, business implementation, etc.) The warehouse data and most of the front-end display data are stored in the data warehouse, but this method has the following problems: [0003] 1. Failure of the warehouse host will result in inaccessibility of the foreground application system and affect the availability of the foreground system; [0004] 2. Once the warehouse host runs a large background program, the front-end application system will access slowly, which will affect the front-end access efficiency; [0005] 3. When a...

AI Technical Summary

Problems solved by technology

[0003] 1. Failure of the warehouse host will result in inaccessibility of the foreground application system and affect the availability of the foreground system;

[0004] 2. Once the warehouse host runs a large background program, the front-end application system will access slowly, which will affect the front-end access efficiency;

[0005] 3. When any foreground data processing program is running, the foreground data table will be updated. If the scheduling is not appropriate, these processing programs will cause the user to fail to access the foreground. The intuitive feeling is that the system is unstable;

[0006] 4. Once an error occurs when accessing the front-end data, it will be displayed directly on the front-end, and it is often at the system level, and the user experience is not good
