An Implementation of GEM — supporting a semantic data model on a relational back-end.
Summary: Implements GEM on INGRES, extending relational model with surrogates, aggregation/generalization, nulls, and multi-valued attributes. Back-end IDM 500 provides transactions, concurrency, and recovery, enabling semantic constructs on a relational processor. (summarized by gpt-5-nano on Feb 09 2026)
