【摘要】 主要研究如何将Web Services技术应用于PDM系统中的产品结构建模。通过基于Web Services的组件通信与基于CORBA和DCOM组件通信的比较,充分体现了Web Services技术完好的封装性、松散的耦合性和高度的集成性。然后,利用一个部署在.NET下的Web服务实例来构建一个产品结构,即通过执行相应的Web服务,从关系数据库中提取出产品数据,并制作成相应的XML文档。从而实现了产品数据在不同平台、不同系统之间使用不同语言来操作,有效地提高了PDM系统中产品数据的通用性。更多还原

【Abstract】 This article examines the Web Services technology in PDM System Product Structure Modeling. Through the comparison of Web Services-based component communication and CORBA and DCOM-based component communication,it fully demonstrates the Good encapsulation,the loose coupling and a high degree of integration of the Web Services technology.Then,an example based on Web Services of .NET is given to build a product structrue. Through the implementation of the corresponding Web services,it can extract product data from relational database,and create the corresponding XML documents. It presents the product data can be operated at different platforms between different systems,and effectively improves the universality of product data in PDM system.更多还原
