机械图形的XML数据存储结构设计

XML Data Storage Structure Design of Machine Graphics

研究了XML数据的存储方法,并在比较现有的存储策略的基础上,提出了采取用户定制的方案。随之进行了图形关系模式的逻辑设计,进行了元数据库设计,组件库设计,并建立了ER集成模型。最后分别建立了元数据表,图形实体,风格属性的物理模型。通过对XML数据存储结构的设计能更好的发挥机械图形标记语言的潜能。

A customized programme is proposed on the basis of comparing the existing storage strategy after studying XML data storage methods. Then, logic design of graphic models, meta-database design,the component design and the establishment of the integrated model ER are done. In the end, physical model of metadata table, graphic entities, style attributes is established. XML data storage structure design can make better use of machinery graphics markup language.
