PDM系统的体系结构分析及应用 摘要 产品数据管理系统(Product Data Management，PDM)作为制造企业实施信息化的集成框架，已经被越来越多的企业所采用。根据企业的实际需求，要求PDM系统的开发由侧重于部门级的设计环节的数据管理与共享向贯穿企业全过程的企业级方向发展，要求系统能够充分集成现有的应用系统，对跨地域的产品数据同样实现信息集成，这就需要对PDM系统进行重新构架，本文就是基于这种背景下研究PDM的体系架构的。 本文首先分析了PDM的产生背景、研究现状及其发展趋势，然后阐述了PDM中的关键技术，如成组技术、客户化技术、网络技术、集成技术等技术信息。接着本文研究了分布式PDM体系结构以及基于XML（Extensible Markup Language）、基于J2EE的体系结构，阐述了各体系结构的组成及其优点，不同的体系结构适用于不同的企业对象，根据企业的实际需求选择不同的体系结构，更有利于企业PDM系统的实施。最后本文介绍了一款较为成熟的PDM系统——Teamcenter，分析了Teamcenter的体系架构，这种体系架构具备了强大的二次开发功能，本文根据某企业的实际需求，提出了对Teamcenter的数据管理部分功能进行二次开发的实施方案，并对其在客户端和服务器端的配置及操作进行了详细的说明。 关键词：　PDM，架构，分布式，XML，J2EE，Teamcenter Abstract Product data management system (Product Data Management, PDM) as an integration framework of the manufacturing enterprises to implement information, has been adopted by more and more enterprises. According to the actual needs, it demands PDM system’s develop from focusing on the design aspects of departmental management and sharing of data throughout the enterprise to the whole process of enterprise-level direction, it requires that the system can fully integrate with existing application systems, and implementation information integration of the product data on cross-boundary, this needs the PDM system to be restructured, based on this background, this article investigate the architecture of PDM. First this article analyses the production, development of the PDM, and then describes the key technologies of the PDM, such as group technology, customized technology, network technology, integration technology and so on. Then this article investigates the distributed PDM architecture and the architecture which based on XML(Extensible Markup Language) and J2EE, also it describes the composition of each system and its advantages, according to the actual needs of enterprises choose a different architecture is more conducive to implement the PDM System. Finally, the paper describes a mature PDM system – Teamcenter, analyses the architecture of it. The arc
