Avoiding Cartesian Products in Programs for Multiple Joins (Extended Abstract)
Summary: Shows that for every join expression there exists an equivalent Cartesian-product-free (CPF) expression that yields a program using joins, semijoins, and projections with cost within a constant factor of optimal. Requires no data-instance restrictions, unlike prior work. (summarized by gpt-5-mini on Feb 09 2026)
