Abstract :
Autonomous index management in native XML DBMSs has to address XML\´s flexibility and storage mapping features, which provide a rich set of indexing options. Change of workload characteristics, indexes selected by the query optimizer\´s "magic", subtle differences in the expressiveness of indexes, and tailor-made index properties ask-in addition to (long-range) manual index selection-for rapid autonomic reactions and self-tuning options by the DBMS. Hence, when managing an existing set of indexes (i.e., a configuration), its cost trade-off has to be steadily controlled by observing query runtimes, index creation and maintenance, and space constraints.
