Quality-driven Integration of Heterogeneous Information Systems

Summary: Introduces multidatabase query planning that treats information quality—completeness, timeliness, and accuracy—as first-class criteria alongside cost. Integrates quality models into view rewriting to select high-quality query-answering plans over heterogeneous sources. (summarized by gpt-5.6-luna on Jul 24 2026)
