Identifying the Extent of Completeness of Query Answers over Partially Complete Databases
Summary: Proposes completeness patterns as table-level selections to denote complete parts of databases. Adapts relational algebra to infer query-answer completeness; proves soundness; extends to instance-aware patterns; shows scalable real-data evaluation. (summarized by gpt-5-nano on Feb 09 2026)
