System RX: One Part Relational, One Part XML

Summary: First hybrid system commingles XML and relational data with equal footing for enterprise management. Native XML storage/indexing and SQL/XML/XQuery compilation/evaluation leverage mature relational infrastructure and 20+ years of data-management research. (summarized by gpt-5-nano on Feb 09 2026)
