3.3 Coverage of the Original FX Demo Reference Architecture

Go to Top

The original FX Demo Reference Architecture provides source material for many concepts and profiles in the Financial Systems Archetype document set. The new document set does not discard that material. It relocates each concern to the proper layer.

Part 1 uses the original FX Demo Reference Architecture as source material for the conceptual architecture. Later parts carry forward the logical, implementation, deployment, testability, and Evidence material.
