Storing DTD-conscious XML data in XEDY

Abstract

In this paper, we discuss the XEDY system for storing DTDconscious XML data in a standard relational databases management system. For this, we propose a database schema for storing any set of XML documents accompanied by DTDs. We demonstrate that our approach reduces number of join operations while executing queries. User will be able to perform query on the XML data stored in XEDY and also be able to extract the XML data stored in the RDBMS without loss of information. We evaluate the performance of the proposed system in term of insertion and extraction speed and database storage requirement.
