【摘要】 分布式对象系统一般存在CORBA与DCOM两种计算模型,但用这两种模型实现的分布式系统间存在互操作性问题.分析了这两种分布式计算模型,说明了影响其系统互操作性的原因,并在此基础上提出了一种新的分布式计算模型———Web服务分布式计算模型.阐述了该模型的体系架构,以及实现时需要的技术组件.经改进后的这一新计算模型,支持了跨平台及跨编程语言的互操作性,成为建立在真正支持互操作性的开放标准基础上的解决方案.更多还原

【Abstract】 Two kinds of computing model available within distributed computing realm are CORBA model and DCOM model. But difficulties occur when interoperability is needed between CORBA system and DCOM system. This paper analyses DCOM model and CORBA model and gives a brief overview of the difference between CORBA and DCOM. The paper brings forward a new distributed computing model of Web Service. The paper also expatiates on architectecture of Web Service and technology in implementing Web Service. This new distributed computing model supports crossplatform and crossprogramming language interoperability. A real solution is presented in the paper based on open standards that can truly support interoperability.更多还原
