机械CAD标准化数据库的实现

Realization of standardized data store for the mechanical CAD

将对象关系数据库的重要概念———集成内容搜索推广到机械CAD标准化数据库 ,讨论了机械CAD建库、动态图形文件更新 ,并且给出了相应的实现方法。

We introduce the concepts of extended intergrate content search to machine CAD standard database. The first concept generalizes the concept of intergrate content search. Furthermore,We discuss how to construct machine CAD database for dynamic update drawing file using intergrate content search.
