非结构化产品信息的分布式模型研究

A DISTRIBUTED MODEL FOR NON STRUCTURED PRODUCT INFORMATION

以ＣＩＭＳ为代表的先进制造技术要求与之适应的产品信息模型的支持．产品信息包含结构化和非结构化两种形式．非结构化产品模型往往建立在异构环境之上，无法抽象成单一的数据库模式．目前对非结构化产品信息还没有形成合适的表达模型和相应的操作模型．提出的一个基于企业级异构环境下的非结构化产品信息的分布式模型，以ＳＧＭＬ／ＸＭＬ标准表达非结构化产品信息，其操作模型能在常规Ｗｅｂ／ＩＮＴＥＲＮＥＴ环境下方便地访问信息。

Advanced manufacturing requires relevant production information model, which is divided into the structured product information (SPI) and the non structured product information (NSPI). The NSPI probably exists in heterogeneous environment and is difficult to be abstracted into single database schema. This paper describes a distributed model for the NSPI catering for the enterprise's heterogeneous environment. The model expresses the NSPI with SGML/XML, and enables access over the Web/Internet with its operation model.
