A Framework for Supporting Data Integration Using the Materialized and Virtual Approaches

Summary: Introduces Squirrel mediators enabling virtual, fully materialized, or partially materialized integrated relations with incremental updates. Two update modes (materialize auxiliary data or keep data virtual) and formal notions of consistency and freshness, with proofs. (summarized by gpt-5-nano on Feb 09 2026)
