【摘要】：动态电子商务作为第三代互联网模式已经成为当今IT业的热门话题之一。这种新型的电子商务模式可以减少人工参与的步骤,提高工作效率和用户使用的便利性。通过动态电子商务技术,降低了系统之间的耦合性,使得企业间的系统集成过程变得更加顺畅。根据航运企业具有业务种类繁多,公司规模较大等特点,采用动态电子商务技术建立航运企业电子商务系统。在这种思想下建立的电子商务系统,既可以解决企业规模不断变化而带来的系统集成问题,同时又可以方便用户的使用,减少人工出错的概率。本航运动态电子商务系统以SOA模型为框架,借以WSDL(网络服务描述语言)、SOAP(简单对象访问协议)和UDDI(统一描述、发现和集成协议)技术来实现。本文针对航运动态电子商务系统的研究与应用,做了如下工作：首先介绍了航运电子商务的发展现状,国内外的研究情况以及存在的问题。并深入研究了动态电子商务的核心技术。然后针对UDDI注册中心部分提出了数据库信息更新模式,提高了数据同步能力和信息的及时性；提出了WSDL处理器机制,实现了WSDL文档的自动生成和解析功能。接下来完成了航运动态电子商务系统的设计过程,包括逻辑设计、软件功能设计、网络结构设计和Web服务设计等。并根据设计思想,完成了UDDI注册中心的建立,Web服务的发布和查询功能以及WSDL处理器的功能。
[Abstract]:Dynamic e-commerce as the third generation Internet mode has become one of the hot topics in IT industry. This new e-commerce model can reduce the steps of manual participation, improve working efficiency and user's convenience. Through dynamic electronic commerce technology, the coupling between systems is reduced, and the system integration process between enterprises becomes more smooth. According to the characteristics of shipping enterprises such as various kinds of business and large scale, dynamic electronic commerce technology is adopted to establish the electronic commerce system of shipping enterprises. The electronic commerce system based on this idea can not only solve the problem of system integration brought by the constant change of enterprise scale, but also facilitate the use of users and reduce the probability of human error. This dynamic E-commerce system is based on SOA model, which is implemented by WSDL (simple object access Protocol) and UDDI (Unified description, Discovery and Integration Protocol) technology. In this paper, the research and application of the shipping dynamic electronic commerce system is discussed as follows: firstly, the present situation of the shipping electronic commerce, the domestic and foreign research situation and the existing problems are introduced. The core technology of dynamic e-commerce is deeply studied. Then, the updating mode of database information is proposed for the part of UDDI registry, which improves the ability of data synchronization and the timeliness of information, and proposes the mechanism of WSDL processor, which realizes the automatic generation and parsing of WSDL documents. Then the design process of shipping dynamic electronic commerce system is completed, including logic design, software function design, network structure design and Web service design. According to the design idea, the establishment of UDDI registry, the publishing and querying function of Web service and the function of WSDL processor are completed.
