UML state machine diagrams give object lifecycles formal run-to-completion semantics. Learn the event [guard] / action model, a PlantUML order example, and the mistakes to avoid.
Event-driven systems hide their behavior across services and topics. UML sequence diagrams — with async arrows, found messages, and alt/par fragments — make that chronology visible without the bloat.
Combined fragments let you model branching and looping in a single UML sequence diagram. This blog explains the core fragment types, shows a PlantUML example for a payment API, discusses trade‑offs, and gives actionable steps to adopt the pattern.
