Abstract

The fact that XML data can be stored in different repositories creates a layer of complexity in efficient XML query processing. Most existing works discussed the query analysis for Native XML Database using XML Query Language such as XQuery and XPath. However, it is inevitable that many XML users still use established database repositories, such as relational and object-relational database, for their XML storage. These databases are recognized as XML-Enabled Database. The query analysis in this database family has not been well-researched. In this paper, we will perform a research on performance of child/descendant XML queries when the data is stored in XML-Enabled Database. For experimentation, we use Oracle DBMS, which has implemented different XML query languages, based on SQL/XML standard.
