【摘要】 传统产品数据管理系统针对性强,可扩展性差,虽然能够临时满足企业的信息化需求,但是随着企业信息化的发展,企业运转模式不断变化,新的需求不断出现,系统的维护和更新代价迅速膨胀。针对传统系统开放性和可维护性上的问题,分析了产品数据管理系统的一般的体系结构以及高可用性系统体系结构的一般特点,对传统系统开发过程中主要支撑技术的优缺点做了系统分析,结合分布式对象技术提出了一种基于Web的高可用性产品数据管理系统体系结构。体系结构更具开放性和可维护性强,并且具有很强的实用性。更多还原

【Abstract】 Traditional PDM system has good pertinence, so it can temporarily meet the informational requirements of the enterprises. With the rapid development of informationalization and the variability of work pattern of the enterprises, new requirements appear and the cost of maintenance and update expands unpredictably. In order to figure out the problem of traditional system, the common architecture of PDM and the general characteristic of high available system architecture are firstly analyzed. Then a systematic analysis is presented to the support technology of PDM. Finally, a web-based high available architecture of PDM is put forward. The architecture is not only more open and maintainable, but strongly practicable.更多还原
