====== 3.4 Traceability to Part 2 Distributed Node-Based Logical Architecture / PIM ======
[[fxdemo:03-part:start | Go To Top ]]

Part 2 defines the reusable, distributed, node-based [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_model|Logical Model (LM)]] / [[dido:99_annexes:annex-b-terms-and-definitions:p:platform_independent_model|Platform Independent Model (PIM)]]. This part specializes the Part 2 logical architecture for the FX Demo.

The FX Demo Logical Profile inherits the Part 2 logical models and applies them to the [[dido:99_annexes:annex-b-terms-and-definitions:f:foreign_exchange_domain|Foreign Exchange Domain]]. It specializes [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node|Logical Nodes]] into FX logical Nodes, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Logical Communication Endpoints]] into FX endpoints, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_definition|Logical Data Structure Definitions]] into FX information definitions, Logical [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Planes]] into FX runtime-plane participation, Logical Interaction Patterns into FX interaction patterns, and Logical [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] relationships into FX traceability relationships.
