【摘要】 Web Services是当今IT业界的关注热点。Web Services的主要目标就是在现有的各种异构平台的基础上构筑一个通用的与平台无关、语言无关的技术层，各种不同平台之上的应用依靠这个技术层来实施彼此的连接和集成。 本文在供应链管理(SCM)的订单处理模块的基础上，研讨Web Services的构架体系，提出了一个基于Web Services的商务开发模型；对SOAP消息的格式、传送处理过程，绑定框架和附件的处理进行了论述；对UDDI的数据模型进行了详细的描述，并说明了服务发布和查找的处理过程；描述了WSDL文档的类型，说明了WSDL文件的编写步骤，对WSDL文件中的各个元素与UDDI服务器中元素的映射关系进行了论述，并说明了如何把WSDL文件与SOAP、HTTP、MIME等协议进行绑定。本文提出的商务开发模型具有一定的独创性和先进性。更多还原

【Abstract】 Web services are the focuses of IT fields today. The goal of Web Services is to provide a common technology layer which has no relation with languange and platform .The application of different platforms needs this technology layer to connect and integrate with each other.On the basis of the purchase-order process module of SCM,this article discusses the architecture of Web Service and brings forward a practical e-business model based on Web Service. Then we analyze the format of SOAP message and explain how to process it,describe the binding framework of SOAP and the process of Attachment. After this,we discuss the data module of UDDI,the public and discovery of service. Finally,we discuss the type of WSDL ducument and how to write a WSDL file;explain the mapping relationship of the elements in WSDL file and UDDI service,how to bind the WSDL file with SOAP,HTTP,MIME protocols. Compared with the available research about B2B,our work,the e-business model based on Web Service,has some original and advanced character.更多还原
