Query Optimization in Heterogeneous DBMS

Summary: Extends query optimization to heterogeneous, autonomous DBMS by calibrating cost models when vendors won't share internal parameters. Introduces a synthetic calibrating DB to tackle unpredictability; evaluated on Allbase, DB2, Informix with ~80% accurate estimates. (summarized by gpt-5-nano on Feb 09 2026)
