O2, an Object-Oriented Data Model

Summary: Formal description of O2, an object-oriented DBMS by the Altaïr group. A type system within a set-and-tuple framework models inheritance and enforces strong typing, providing rigorous OO semantics for data management. (summarized by gpt-5-nano on Feb 09 2026)
