Design and Implementation of a Heterogeneous Database Synchronization Mechanism Based on the Netgap

In allusion to the network environment of information communication using the netgap, this paper proposes a heterogeneous database synchronization mechanism based on the shadow table method. In this paper, the network environment of the netgap is described, and the overall architecture of the synchronization system is introduced, and the implementation of the module such as change data capture, incremental file generation, data synchronization operation and exception handling is proposed. Finally, the database synchronization mechanism is verified by the application of the data acquisition system of an organization.
