SIM-ZONE: A System of Information Management for Defensible Information
Enterprises often believe Data Vault is implemented when the physical model loads cleanly and history is captured, yet defensibility still fails under scrutiny. The gap is trust-plane fragmentation: conceptual meaning, logical integration, and physical traceability evolve independently and cannot be reconciled into a single provable story. SIM-ZONE frames this as a System of Information Management that binds those dimensions into one trust plane. The article distinguishes warehouse completeness from decision-grade defensibility and explains why local incentives make semantic and grain decisions easy to defer. It closes on the reality that proof obligations and authority boundaries determine where accountability defaults when meaning cannot be demonstrated.
