Method and device for data synchronization between application systems

Abstract

The invention discloses a method and a device for synchronizing data among application systems. The method comprises the steps that: a buffer module is initialized and the information sets of the application systems and the information sets of synchronization operation are loaded and analyzed to a data synchronization module; all the information sets of the application systems and the informationsets of the synchronization operation which need synchronization are obtained; a polling application system is used for carrying out data synchronization operation; and whether the updating of the data synchronization is successful is judged, if not, the information sets of the application systems and the information sets of the synchronization operation, which are not successfully synchronized, are put into the buffer module and the data synchronization updating to the information sets is carried out by utilizing a thread polling application system until the updating is successful; if so, the cache of the application systems is updated. By adopting the technical proposal, just simple modification on the existing information sets of the application systems and the information sets of the synchronization operation can meet new application needs when an application scene changes and the data synchronization can be completed even if the application systems have accidents.

Description

technical field [0001] The invention relates to the technical field of data buffer synchronization, in particular to a method and device for data synchronization between application systems. Background technique [0002] In an application environment, there will be various application systems to solve different businesses, and each application system will involve data access to databases related to other application systems. And there will be some basic data among these application systems that are strongly related, such as personnel information, department information, etc. When a piece of basic data of an application system is modified, the corresponding data of other application systems associated with it must be guaranteed. Be modified, that is, to ensure data consistency. How to ensure the consistency of basic data in different application systems is very important. [0003] Usually, a manual method is used to synchronize the basic data that needs to be modified one b...

AI Technical Summary

Problems solved by technology

[0007] Although data synchronization can be performed through the configuration file, the information in the configuration file is a collection of application system information and a collection of synchronization operation information, and the synchronization operation of data can be realized by hard coding; when a new application system wants to be notified of database operations , it is also necessary to modify the code, which affects the scalability of the application system

Moreover, when the application system that needs to be synchronized fails, the data synchronization will be interrupted, making the data synchronization unsuccessful.
