Conceptual Model (CM)

Return to Terms and Definitions

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 modelling, platform-specific modelling, 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 artefacts, platform features, software structures, database structures, middleware structures, deployment structures, or runtime components.

model that represents concepts in a domain and relationships among those concepts

Adapted for the FX Demo Reference Architecture

A conceptual model defines domain-level meaning and scope.

A conceptual model precedes Logical Models, Platform-Independent Models, Platform-Specific Models, and implementation artefacts in the architectural refinement chain.

Conceptual models organise domain meaning. Logical models organise architectural concerns. Platform-specific models organise selected technology realisations of those concerns.

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 organises those concepts into architectural viewpoints such as policy control, information exchange, evidence, audit, and governance.
