Performance comparison of property map and bitmap indexing Ashima Gupta, Karen C. Davis, and Jennifer Grommon-Litton   View Paper (PDF)   Return to Papers Abstract using cost models to simulate their storage and query processing costs for different kinds of queries over a benchmark schema. We identify parameters that affect performance of these indexes and determine situations in which either technique gives significant improvement over the other. We also explore ways to improve PMap design to enhance performance. DiSC'03 © 2003 Association for Computing Machinery
