Data Structures for an Integrated Data Base Management and Information Retrieval System

Summary: Extends the relational model with Non-First-Normal-Form relations to integrate structured data manipulation and textual retrieval, introducing nest/unnest algebra and SEQUEL extensions. Proposes indexes over word fragments, words, and word sequences for efficient structured-text access. (summarized by gpt-5.6-luna on Jul 24 2026)
