摘要:
XML的DTD机制不足以表现结构化数据的语义.本文在路径约束的基础上,提出一种新的语义映射机制.引入域的概念描述结构化数据到XML数据的结构映射,将结构化数据的平面结构映射为XML数据的树状结构.通过有域层次的键规则表达式,将结构化数据中分散在各表中的键的定义映射到XML数据中.利用域的概念和模板匹配的原理,引入域关系表达式及其扩展表达式来实现结构化数据到XML数据的语义映射.由此构成的语义映射机制可以和XML数据的模式抽取很好的集成在一起,体现数据的语义约束并为数据库对XML数据存储和查询的优化提供有效信息.
Abstract:
The DTD mechanism is deficient in describing the semanteme of structured data. Based on path constraint, a new mechanism for semantic mapping is proposed. The concept of domain for describing the structure mapping from structured data to XML data is introduced, through which tabular structure of structured data can be converted to tree structure of XML data. Regular key expression with hierarchy of domain is defined to map key definition in tables of structured data to that of XML data. Using the concept of domain and the principle of template matching, the domain-relationship expression and its extension are developed to realize the semantic mapping from structured data to XML data. The above mechanism can be well integrated with schema extracting from XML data to depict semantic constraint of data and provide sufficient information for database to optimize storage and query of XML data.
