Causes for Query Answers from Databases, Datalog Abduction and View-Updates: The Presence of Integrity Constraints
University of Washington（华盛顿大学）；Carleton University（卡尔顿大学）
英文摘要：
Causality has been recently introduced in databases, to model, characterize and possibly compute causes for query results (answers). Connections between queryanswer causality, consistency-based diagnosis, database repairs (wrt. integrity constraint violations), abductive diagnosis and the view-update problem have been established. In this work we further investigate connections between query-answer causality and abductive diagnosis and the view-update problem. In this context, we also define and investigate the notion of query-answer causality in the presence of integrity constraints.
