Trio: A System for Integrated Management of Data, Accuracy, and Lineage

Summary: Introduces Trio, a DBMS that treats data, accuracy (uncertainty/probabilistic/fuzzy/incomplete) and lineage as first-class, integrated artifacts. Proposes a simple SQL-extension and prototype design to unify provenance and uncertainty management for practical applications. (summarized by gpt-5-mini on Feb 09 2026)
