Query By Diagram: A Graphical Environment For Querying Databases

Summary: QBD* is a graphical query-by-diagram tool enabling non-experts to query ER schemas, with relational completeness and recursive queries. Innovations: set ops on same-id tables; schema refinement and metaschema querying; path contraction/ISA replacement. (summarized by gpt-5-nano on Feb 09 2026)
