摘　　要：分布式数据库系统包含多个节点,它们之间通过网络连接共同工作,随着移动计算的广泛应用,数据同步技术在分布式数据库系统中发挥着越来越大的作用。提出一种基于Mobillnk技术的数据同步中间件的设计思想,系统以Sybase Adaptive Server Enterprise作为统一数据库进行二次开发,在广域网络中实现分布式商业POS系统的进销存管理。The distributed database system comprises several nodes, they jointly work through network connection. Along with the wide use of mobile computing, data synchronization technique plays an increasing important role in distributed database system. This paper presents a design thought of data synchronizing middleware which is based on the technique of Mobilelink. The system uses the Sybase Adaptive Server Enterprise as the Unification Database to carry on secondary development to realize purchase sales inventory management of the distributed Commerce POS system in wide area network.
