IBM Fast Path to DB2 9 for Experienced Relational DBAs
IBM Training Ability to capture and analyze EXPLAIN VISUAL EXPLAIN information
XML data is stored and retrieved within a relational database for a data-centricapplication by means of mapping XML schema elements to database tables. There are
concerns that the queries and updates to this database are slow due to the number of joins
required in the SQL. What is the best option for improving the storage and retrieval of
this XML data?
A. Modify the current XML schema by merging all of the XML documents into a main
XML document and query using XPath.
B. Transform XML documents into canonical form before persisting.
C. Store the XML data as CLOBs without decomposing them into relational tables and
provide an 'id' based lookup.
D. Modify the current XML schema by converting elements to attributes where possible
and re-map to tables in order to reduce the number of tables and therefore the number of joins required.
