Architecture — Layer 01 of 07

Integration

How systems connect and exchange information across the enterprise.

The Integration layer designs how Microsoft, SAP, Oracle, Salesforce and custom applications exchange data and trigger each other — not as point-to-point connections, but as a deliberate topology.

Principles

The design rules for this layer.

01

Asynchronous by Default

Decouple services through event-driven messaging. Synchronous HTTP coupling is restricted strictly to real-time client queries.

02

Canonical Data Contracts

No two applications exchange raw database schemas. All communications pass through versioned, strictly validated schema contracts.

03

Zero Point-to-Point Spaghetti

Integrations route through a centralized message exchange topology. Direct system-to-system database bridges are strictly prohibited.

Deliverables

What we produce for this layer.

01

Enterprise Integration Topology Map

Definitive map of event brokers, API gateways, protocol translations, and messaging queues across all active systems.

02

OpenAPI & AsyncAPI Schema Registry

Centralized, version-controlled repository of all service contracts, payload definitions, and boundary validation schemas.

03

Integration Error & Dead-Letter Protocol

Automated retry policies, circuit breakers, and alert mechanisms for distributed transaction failures and network partitions.

04

Legacy Core Adapter Specifications

Safe bidirectional synchronization specifications for SAP, Oracle, Microsoft, and custom on-premise engines.

Current vs designed

What changes when this layer is designed.

Current state
  • Point-to-point connections added system by system
  • Integration logic duplicated across projects
  • No shared view of what connects to what
Designed state
  • A defined integration topology
  • Reusable connection patterns
  • One map of how systems reach each other
Works With Your Systems

Designed to work with the enterprise systems you already use.

ACHORD does not replace the systems you already paid for. We design how SAP, Oracle, Microsoft Dynamics, Salesforce and your custom applications exchange data, reconcile it, and hand off decisions.
