Abstract
There is a structural discrepancy between XML documents and relational databases. Hence, special data structures are required in order to represent the hierarchical structure of XML documents in storing the XML documents in relational databases. The structural information is required in querying XML documents and publishing the stored relational data in XML documents. In this paper, we propose a method for storing XML documents in relational databases, in which the structural information of XML DTD as well as the XML documents is stored. The structural information of XML documents is also stored. The XML DTD is restored by using the stored structural information and provided to users in creating queries against XML documents. XML documents can be also restored using the stored structural information. The XML queries written in XQuery are processed by exploiting the structural information of DTD that is represented in conjunction with the relational tables in which XML documents are stored.
