VXMLR: A Visual XML-Relational Database System

We demonstrate a visual based XML-Relational database system where XML data is managed by commercial RDBMS. A query interface enables users to form path expression based queries against stored data visually. Statistics about data and a special path directory are used to rewrite path expression based queries into efficient SQL statements involving less number of joins.
