Implementation of General Constraints in SIM

Summary: Describes SIM, an OO-DBMS with no user-defined methods, supporting general constraints (aggregates, quantifiers, cross-object refs). Constraint checks are generated via stored queries, deferred to full updates, with rollback on violation; the parser can prune checks, and structural constraints are enforced separately.
