BPMN Diagram
3/20/2026
This BPMN diagram is used to standardize how an online order moves across Customer, Sales, Warehouse, and Shipping—from submitting an order and validating payment, through inventory checks with a backorder/restock path, to pick & pack, shipment creation, carrier handoff, and tracking sent before receipt. It helps teams pinpoint handoffs, decision points, and rework loops (payment retry/cancel) to reduce delays. Operations managers, process analysts, and fulfillment leads would use it.

Sequence Diagram
3/18/2026
This sequence diagram is used to clarify the end-to-end message flow in Kafka from a Producer sending Produce(topic, partition, key, value) to a Kafka Broker acking with an offset, then a Consumer Group joining and receiving partition assignments before fetching records from the last committed offset. It helps teams reason about delivery guarantees, partition ownership, and when offsets are persisted via CommitOffset and the broker’s write to the Offset Store. It’s used by backend engineers, SREs, and platform tea...

Class Diagram
3/18/2026
This class diagram is used to clarify an event-sourced architecture by showing how CommandBus routes a Command to a CommandHandler, which loads and saves an AggregateRoot through an EventSourcedRepository backed by an EventStore. It helps teams reason about consistency, versioning, and event flow as AggregateRoot emits DomainEvent instances that the EventStore appends, loads, and publishes via an EventBus. Developers and architects use it to design write models and read models, where a Projector subscribes to even...
