Data Integration: A Theoretical Perspective

Summary: Theoretical overview of data integration formalizing modeling choices (sources-as-views vs global-as-view), treating sources as views over a global schema and characterizing their trade-offs. Focus on query answering, logical reasoning about queries, and principled handling of inconsistent sources. (summarized by gpt-5-mini on Feb 09 2026)
