21. Tamino... is the Information Server for Electronic Business is the first native XML DBMS can store and manage any data attaches directly to the Internet without programming turns any data source into Internet objects can access and integrate any existing data source supports XQL as well as SQL for relational data supports NT, Unix and Mainframe systems

22. SQL XML XML over SQL (SQL is not optimal) This is slow, difficult and proprietary is right This ensures performance, and extensibility Tamino: A Native XML Database XML
