The Design And Implementation Of Distributed Data Synchronization System Based On JAVA And XML

Data synchronization comes from data storage. The object of data synchronization is data. In order to solving the efficiency of different storage medium, data synchronization has been created. According to the principle, data synchronization could help enterprise improve the problem of system performance. The information system of enterprise can design as center server and query server. According to the special requirements, center server is just responsible for inserting or updating or deleting. In addition, query server is just responsible for inquires. They can be synchronized by data synchronization system to improve the performance of the information system.The paper designs and implements the distributed data synchronization system based on JAVA and XML. The research has been done in this paper on the data synchronization solutions. The paper first gave an introduction of the fundamentals of distributed database systems, as well as the relevant technologies to achieve these systems. Then a full analysis of nowadays available data synchronization methods was presented by the author. Finally, based on the causes and solutions of data synchronization problems, the author put forward a distributed database mode based on control table and XML. The system was based on Java and XML technologies, both of which had nothing to do with the platform. In the system, database trigger was selected from all the existing data capture technologies after a thorough analysis to capture database changes and alter table was employed to save all the changes. In the meanwhile, XML documents were used as an intermediary to store and exchange the data changes thus achieving the purpose of data synchronization.Finally, NEUSOFT information management system was given as an example to the Data Synchronization System. In the meanwhile, the experiment results ensured the system significantly realize the demands of NEUSOFT.
