基于构件技术的产品数据管理服务模型

Product data management system service model based on component technology

论文针对产品数据管理系统对于集成和扩展性的要求 ,基于 CORBA (comm on object request brokerarchitecture)软件总线规范提出了一个产品数据管理系统的服务模型。该模型通过应用接口服务实现系统集成 ,统一了系统核心功能和集成功能的实现方法 ;通过全局数据模型和全局功能模型的管理进行系统的扩展 ,大大提高了系统的适应性。该方法充分利用了分布式技术的优势 ,系统集成和扩展的效率均大大优于传统的专用集成语言。

A service model for product data management based on CORBA is proposed for system integration and the extension of product data management system. In this model, the application integration is realized through application interface services, which are consistent with the realization method of system core functions. The system extension is realized through the management of global data model and the global function model. The model takes advantage of distributed technologies, so the efficiency of system integration and extension is superior to traditional methods using special interfaces or languages.
