Statistical Learning Techniques for Costing XML Queries
Summary: Comet provides XML query cost modeling via new simple-path statistics and system catalogs. It uses transform regression, not analytic formulas, to predict XML operator costs, enabling self-tuning as workloads evolve; validated on XNav with synthetic, benchmark, and real data.
