Answering Queries In Relational Databases

Summary: Formal framework for answering queries in relational databases: queries are attribute subsets; contexts are joinable subsets of schemes. Unambiguous contexts are formalized; they ground universal-relations and relation-uniqueness notions and maximal objects. (summarized by gpt-5-nano on Feb 09 2026)
