摘　　要：多机系统中的计算机间数据交互是实现多机系统协同工作的关键,也是实现系统备用功能的主要手段。为了分析多机系统内部数据交互方法的优点和缺点,对专用接口数据交互、基于共享存储区数据交互和分布式数据交互3种实现方法进行了说明,并简述了以数据为中心的订阅/发布机制的分布式多机系统开发过程。Data interaction between computers in multicomputer system is the key to realize the computers cooperative work in muhicomputer system, and is also the main method to realize the alternate function of multicomputer system. In order to ana- lyze the advantages and disadvantages of the internal data interaction in multicomputer system, three kinds of data interaction methods： data interaction by special data interface, data interaction based on the sharing memory area and distributed data in- teraction are expounded in this paper. The developing process of the distributed muhicomputer system with publish/subscribe mechanism which takes data as a center is described.
