An xml index advisor for DB2

XML database systems are expected to handle increasingly complex queries over increasingly large and highly structured XML databases. An important problem that needs to be solved for these systems is how to choose the best set of indexes for a given workload. We have developed an XML Index Advisor that solves this XML index recommendation problem and is tightly coupled with the query optimizer of the database system. We have implemented our XML Index Advisor for DB2. In this demonstration we showcase the new query optimizer modes that we added to DB2, the index recommendation process, and the effectiveness of the recommended indexes.
