Order management system integrating ATP (Available-to-Promise), CDB (Customer Database), and FOE (Fulfillment Order Engine) services through dedicated ACL microservices and MongoDB data stores. Frontend UI routes order requests through fom-m-order Service, which validates against ATP via acl-atp Service and persists to Order Store MongoDB, while triggering downstream fulfillment via DL and FOE Services. This architecture enforces clear service boundaries, decouples data access through ACL services, and enables independent scaling of order processing, validation, and fulfillment workflows. Fork this diagram to customize service names, add API gateways, or extend with event streaming for asynchronous order processing. Consider adding message queues between cmds Service and fulfillment services for resilience in high-volume scenarios.
