A Data Synchronization Method Oriented to Custom Hierarchical Multi-node System

In the modern enterprise system, data synchronization programs need to support data cloud storage to ensure data consistency, integrity, and security between two devices. The paper addresses to some observation network system as a hierarchical multi-node system. In its application development process, the synchronization functions in existing database management system cannot meet its system requirements. A kind of data synchronization method oriented to custom hierarchical multi-node system was brought out. The program floe and synchronization task queue structure to implement the method were also given.
