Normalization mapping from redundant XML schema to relational schema
Jian Chong-junb · Journal of Yangzhou University · 2011
This article analyzes the XML(extensible markup language) schema grammar to find the root cause of the redundancy,eliminates the attribute redundancy,element redundancy and nesting redundancy by the attribute redundancy elimination rule,the element redundancy elimination rule and the nesting redundancy elimination rule respectively,realizes the relation mapping from XML schema to relational schema by the relation mapping rule.The algorithm not only realizes the normal mapping from XML schema to relational schema,but also realizes the mapping from the redundant XML to the relational schema.The mapping is non-reversible.
