Return to Requirements

Each FX logical Node SHALL specialise a Logical Node from Part 2.

Part 3, Section 17.3: FX Logical Node Requirements.

Specialization preserves the architectural inheritance defined by the Part 2 Logical Architecture while allowing the FX Demo Logical Profile to introduce domain-specific logical behavior. This ensures consistency between the generic platform-independent architecture and the Foreign Exchange specialization.

This requirement applies to every FX logical Node defined by the FX Demo Logical Profile.

It applies specifically to:

• logical Node specialization;
• architectural inheritance;
• logical architecture reviews; and
• profile maintenance.

Verification SHALL confirm that every FX logical Node explicitly identifies its corresponding Part 2 Logical Node.

Verification activities should include review checks confirming that:

• every FX logical Node has an identified parent Logical Node;
• specialization relationships are documented;
• inherited architectural meaning is preserved; and
• no orphan logical Nodes exist.

This requirement preserves traceability between the Part 2 Logical Architecture and each FX logical Node.
