【摘要】 竞争和合作的国际化，促使企业必须开拓市场，充分利用各地资源优势，形成企业间紧密合作。基于CORBA与Web技术的PDM系统能够为产品信息共享和应用集成提供有力的支持，因此成为PDM技术发展的方向。 本文在分析CORBA分布式对象模型和Web技术的基础上，提出了基于CORBA／Web技术的产品信息管理系统体系结构，建立了基于STEP标准的集成产品信息模型，通过EXPRESS语言到数据库定义语言的映射规则，得出了各论题模型的数据库结构，然后提出了基于CORBA组件的Web数据库访问方案，分析了该模型在开发基于Web的PDM系统中的优点，并对CORBA组件的实现过程和方法作了详细说明，给出了基于PDM系统的应用集成方案，对PDM与CAD系统接口的开发进行了尝试，最后简单介绍了所开发的软件原型系统。更多还原

【Abstract】 Because of the internationalization of the competition and cooperation, enterprises have to expand their markets and form their compact cooperation with using the advantage of resource and sharing the information. The PDM system based on the CORBA and Web technology becomes the development orientation, because it can provide powerful support for the share of the product information and the application integration.On the basis of the analysis of CORBA distributed object model and Web technology, this paper presents the architecture of the product information management system. The integrated product information model based on STEP is established. The database structure of the topic models is inferred through the mapping rule from EXPRESS language to database definition language. And then the Web database access procedure based on the CORBA component is presented. The advantages of the model in developing PDM system based on Web are analyzed and the implementation procedure and method of the CORBA component are detailed described. The application integration procedure based on the PDM system is presented and the attempts to develop the interface between PDM and CAD are performed. Finally the prototype system is introduced simply.更多还原
