State Diagram
4/16/2026
This State Diagram is used to model how a CI/CD pipeline job moves from queued to running and then to passed, failed, or cancelled, including cancellation before or during execution and continued activity while running. It helps teams clarify lifecycle rules, runner assignment, completion outcomes, and cancellation behavior for troubleshooting and automation design. DevOps engineers, platform teams, and software developers would use it.

This ER diagram is used to organize the core parts of API design best practices by linking a central API design domain to REST, versioning, authentication and authorization, and documentation. It helps teams plan consistent resource URLs, HTTP method usage, backward compatibility, OAuth or API key security, and clear OpenAPI-based docs. Software architects, backend developers, API product teams, and technical writers would use it.

A state diagram for a CI/CD pipeline job is used to map how a job moves from queued to running and then to passed, failed, or cancelled based on events such as runner assignment, execution success, execution failure, or cancellation. It helps teams clarify job lifecycle rules, troubleshoot pipeline behavior, and document automation logic. DevOps engineers, platform teams, QA engineers, and developers would use it.

A state diagram for a CI/CD pipeline job maps how work moves from Queued to Running, then ends as Passed, Failed, or Cancelled, with cancellation possible before or during execution. It is used to define valid job behavior and terminal outcomes, helping teams reason about automation flow, error handling, and interruption rules. DevOps engineers, platform teams, QA leads, and developers would use it to align pipeline design and operations.

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.

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...

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...

ER Diagram

This ER Diagram organizes the PEMDAS order of operations by linking the PEMDAS entity to its rule categories—Parentheses (1st), Exponents (2nd), Multiplication & Division (3rd, left-to-right), and Addition & Subtraction (4th, left-to-right)—and then connects PEMDAS to a worked example, 3 + 2 × (4^2 − 1), resolved step-by-step to 33. It’s used to prevent calculation mistakes by clarifying precedence and tie-breaking, helping students, teachers, and tutors explain and apply the rules consistently.
