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

Part 0 provides the Document Set Overview and Reader’s Guide for the Financial Systems Archetype. It explains the purpose of the document set, the relationship to SDIS/SIP-RA, the layered document structure, the onion model, document responsibilities, layering rules, and navigation guidance.

Part 1 defines the Conceptual Architecture for the Financial Systems Archetype. It establishes the conceptual definitions, classification model, separation-of-concerns model, [[dido:99_annexes:annex-b-terms-and-definitions:r:runtime_plane|Runtime Plane]] concepts, [[dido:99_annexes:annex-b-terms-and-definitions:t:traceability|Traceability]] concepts, [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] concepts, and conceptual requirements that later parts preserve.

This part depends on both Part 0 and Part 1. It relies on Part 0 for the document-set map and layering rules. It relies on Part 1 for the conceptual foundation.

Part 2 performs the second architectural role within the document set. It defines a single distributed, node-based Logical Architecture / PIM that conforms to Part 1. It specializes Part 1 concepts into platform-independent logical Nodes, [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_node_role|Logical Node Roles]], [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_communication_endpoint|Logical Communication Endpoints]], [[dido:99_annexes:annex-b-terms-and-definitions:l:logical_data_structure_definition|Logical Data Structure Definitions]], logical Runtime Planes, logical interaction patterns, logical governance relationships, and logical traceability relationships.

Table 2-1 summarises the relationship among Part 0, Part 1, and Part 2.

Table 2-1:	Relationship among Part 0, Part 1, and Part 2

^ Part ^ Role ^
| Part 0 | Explains how to read and use the Financial Systems Archetype document set. |
| Part 1 | Defines the Conceptual Architecture used by the Financial Systems Archetype document set. |
| Part 2 | Defines a distributed, node-based Logical Architecture / PIM that conforms to Part 1. |

Part 0 tells readers how the document set works. Part 1 defines the concepts at the centre of the architecture. Part 2 defines a platform-independent Logical Architecture that builds outward from those concepts.
