QRelX: Generating Meaningful Queries that Provide Cardinality Assurance
Summary: QRelX auto-generates alternate queries that satisfy cardinality and closeness constraints, fixing cardinality assurance gaps in DB systems. It uses query-space transformation, proximity search, and incremental cardinality estimation, with an interactive demo. (summarized by gpt-5-nano on Feb 09 2026)
