Overview

Earlier, the integration architecture was structured with a cloud-hosted ERP system (Oracle EBS R12) seamlessly connected to an on-premises Oracle Transportation Management (OTM) environment. Data exchange between the two systems was facilitated through a Database Link (DB Link).

Revised Architecture

The integration has now been upgraded to a modern cloud architecture:

- Cloud-based ERP System integrated with Oracle Transportation Management Cloud (OTM SaaS on OCI)
- Both systems are hosted on Oracle Cloud Infrastructure
- Integration is now performed using:
     - REST APIs / Web Services (Recommended)
     - Secure, scalable, and loosely coupled architecture

---

Key Improvements

- Eliminated dependency on DB Links (not suitable for cloud/SaaS)
- Improved security with API-based communication
- Better scalability and performance
- Supports real-time or near real-time data exchange
- Aligns with Oracle’s cloud best practices

---

Typical Integration Flow

- ERP triggers shipment/order data via API
- OTM Cloud processes planning & execution
- Status updates sent back to ERP via API
