Zhu Qing, Wangdong Yang · 2010
This paper analyzes the sets in the data model of XML document described with SCHEMA and defines the dependency relation, value dependency relation and two kinds of fetching value relation in the described sets. According to these relations and the constraints defined by the SCHEMA, it also creates a group of rules mapped SCHEMA to relational database. We have proved that the mapping between SCHEMA and relational database is integral and the relation after mapped conforms to the 3rd normal form.
