基于消息队列和XML的数据同步技术研究

Research on Database Synchronization Technology Based on Message Queue and XML

数据同步技术一直是影响分布式计算机系统应用的一个决定性因素，在简单介绍了现有的数据同步技术的基础上，提出了采用Windows的消息队列和二进制XML编码技术相结合的数据库同步方案，给出了具有较高数据压缩比率的二进制XML编码算法，实现了在窄带网络环境下的数据同步，并对数据同步的导入导出策略进行了设计，仿真测试的结果表明该同步算法相较于传统的数据同步算法具有很好的网络传输特性及数据同步的可靠性，这些对于数据同步技术的研究，在理论与实践上都有一定的借鉴意义。

Database synchronization is always the key fact to the application of distributed computer system, on the basis of introducing current data synchronization technology, the new data synchronization technology that based on message queue and binary XML was pointed out, and the binary coding algorithm, which has high data compressibility, and has the ability of transmitting under the background of narrowband network was also given out, and in the end the data input and output strategy were both developed. The simulation results show that the new data synchronization technology that based on message queue and binary XML has better network transmission performance and reliability than that of traditional data synchronization algorithm. All this work is significative for researching the data synchro- nization technology both on theory and practice.
