Combi-Operator – Database Support for Data Mining Applications

Summary: Identifies high-dimensional aggregation across all low-dimensional projections (e.g., histograms) as a key data-mining subproblem. Introduces Combi-Operator, a new SQL-operator aligned with OLAP GROUP BY; memory-aware implementations yield up to 10× speedups over existing DB methods. (summarized by gpt-5-nano on Feb 09 2026)
