Architecture

Arqua has developed a coherent reference architecture for Enterprise Intelligence.

The architecture defines how operational reality becomes governed representation, institutional memory, runtime context, coordinated action, authorised consequence and revised understanding.

Caption: The complete architecture from operational reality through representation, memory, runtime coordination, consequence and learning.

Alternative text draft: Architecture diagram showing Arqua Canonical Architecture, including operational reality, observed evidence, representation intelligence, accepted institutional representation, institutional memory, runtime context assembly, enterprise control plane, governed coordination, execution admissibility, operational consequence and representation evolution, and the feedback or governance relationship between them.

Layered Enterprise Architecture Framework

Constitutional Architecture
Defines what every intelligent enterprise requires.

↓

Enterprise Implementation Patterns
Defines how those constitutional capabilities are implemented.

↓

Technology Realisations
Shows how platforms such as Microsoft Fabric, AWS, Kafka, Stardog and others realise implementation patterns without becoming the architecture.
