As XML has become popular as a document standard in the World Wide Web, a lot of research has been done on the XML storage systems for storing and managing XML documents using existing DBMSs.Most of the research activities, however, assume a relational DBMS instead of an object-oriented/object-relational (OO/OR) DBMS, which offers more powerful modeling capabilities.In this paper, we present the design and implementation of an XML storage system designed for an OO/OR DBMS.Specifically, we first analyze the mapping from an XML document structure to OO/OR database schema.Second, we propose a method for describing the mapping using a standard language called the XML Schema Language.Third, we propose system catalog classes for storing the mapping information specified by users in the database.Fourth, we propose a detailed algorithm for storing XML documents in an OO/OR database, based on the mapping information.We believe the proposed system is practically usable for object-oriented programmers and DBMS implementors.
