Querying Database Knowledge

Summary: Argues that substantial database knowledge warrants querying, unifying data and knowledge under a single access instrument. Proposes a knowledge-rich DB framework and a two-statement language (retrieve-data, describe-knowledge) with algorithms for sound, finite describe answers. (summarized by gpt-5-nano on Feb 09 2026)
