====== Conceptual Model (CM) ====== [[dido:99_annexes:annex-b-terms-and-definitions:start|Return to Terms and Definitions]] ===== Discussion ===== A conceptual model describes the relevant concepts in a problem domain and the relationships among those concepts. Within the FX Demo Reference Architecture, a conceptual model establishes shared meaning before logical modeling, platform-specific modeling, or implementation work begins. It identifies domain concepts, policy concepts, governance concepts, information concepts, roles, relationships, constraints, assumptions, and boundaries. A conceptual model supports agreement about meaning. It does not define implementation artifacts, platform features, software structures, database structures, middleware structures, deployment structures, or runtime components. ===== Definition ===== //model that represents concepts in a domain and relationships among those concepts// ===== Source ===== Adapted for the FX Demo Reference Architecture ===== Note ===== A conceptual model defines domain-level meaning and scope. A conceptual model precedes Logical Models, Platform-Independent Models, Platform-Specific Models, and implementation artifacts in the architectural refinement chain. Conceptual models organize domain meaning. Logical models organize architectural concerns. Platform-specific models organize selected technology realisations of those concerns. ===== Example ===== A conceptual model identifies jurisdiction, sovereignty, residency, governed release, release evidence, reporting party, receiving authority, policy authority, and policy decision as domain concepts. A logical model organizes those concepts into architectural viewpoints such as policy control, information exchange, evidence, audit, and governance.
