Research Of Cloud-platform Database Synchronization Based On Event-driven

With the improvement of the information age to the modern business enterprise information processing capacity requirements, heterogeneous database synchronization technology has been more widespread attention. Establishing a stable, reliable database synchronization system has a very important practical significance for the modern enterprise.This thesis, based on the familiar domestic database synchronization technology, discusses the method based on CDC (Change Data Capture incremental extraction solution) for data synchronization and update steps and the effect of the application of data analysis, design and architecture of the data model based on CDC. In the system design and implementation, application-based event-driven CDC technology, the central database of the Graduate School of Chinese Academy of Sciences conducted a synchronized, so the lack of credibility of aggregated data extraction, the extraction time data inconsistencies in the data hierarchy prone to errors reported issues have been resolved.System application shows that it, relative to other data synchronization method, has advantages in scalability, reliability, initiative and flexibility. The use of event-driven CDC technology for data synchronization, reducing network traffic pressure, with high accuracy features, outstanding performance in practical terms, is a better method for heterogeneous database synchronization. The method based on event-driven CDC technology to synchronize database synchronization technology has a wide range of applications, with a very broad application prospects.
