Converting XML DTD to Database
Feng Ye · 2009
This paper discusses the method of converting XML DTD to Relational Schema of database. It provides an algorithm of analyzing XML DTD, accessing to elements, attributes, as well as the relationship of elements contained by XML DTD. It creates the DTD graph to express the elements, attributes and semantic constraints of XML DTD. It then optimizes the DTD graph, and finally converts DTD to relational schema via DTD graph. Finally, this paper gives the converting rule from semantic constraints of DTD to that of Relational Schema. The method can not only obtain the structure information of DTD, but also maintain the semantic constraint of DTD.
