A Demonstration of FlexPref: Extensible Preference Evaluation Inside the DBMS Engine
Summary: Extensible in-DBMS framework FlexPref unifies skyline, top-k, k-dominance, and k-frequency in a single code base. Three simple registration functions enable integration; once inside, it runs core preference queries with standard operators, demonstrated in PostgreSQL. (summarized by gpt-5-nano on Feb 09 2026)
