[[fxdemo:02-part:start|Go to Top]]

The Financial Systems [[dido:99_annexes:annex-b-terms-and-definitions:a:archetype|Archetype]] document set provides a layered architecture for applying structured information processing principles to [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_system|financial systems]]. [[fxdemo:00-part:start]] explains the document set, the layered structure, the reader’s guide, and the rules for preserving separation among conceptual, logical, implementation, deployment, testability, and [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|evidence]] concerns.

[[fxdemo:01-part:start]] defines the Conceptual Architecture. It establishes the conceptual foundation for the Financial Systems Archetype, including classification, core conceptual elements, [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]], [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|traceability]], evidence, and separation-of-concerns concepts.

This part defines a distributed, node-based Logical Architecture as a [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|Platform Independent Model (PIM)]]. It specializes the concepts defined in Part 1 into logical [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Nodes]], logical [[dido:99_annexes:annex-b-terms-and-definitions:n:node_role|Node Roles]], logical [[dido:99_annexes:annex-b-terms-and-definitions:c:communication_endpoint|Communication Endpoints]], logical information structures, logical Runtime Planes, logical interaction patterns, logical governance relationships, and logical traceability relationships.

This part defines one Logical Architecture that conforms to the Part 1 Conceptual Architecture. It does not define every possible Logical Architecture that conforms to Part 1. Other logical architectures conform to Part 1 by preserving the conceptual definitions, separation of concerns, traceability, evidence orientation, and layering rules defined there.

This part does not define the FX Demo Logical Profile, Phase 0 implementation mappings, deployment procedures, Crucible scenarios, acceptance checks, scripts, repository structure, or runtime evidence. Later parts and supporting repository documentation address those concerns.
