Tutorials, guides, and best practices for UML diagramming
Use Mermaid Crow's Foot notation for application schemas and PlantUML Chen notation for conceptual models. Compare keys, cardinality, scope, and tradeoffs.
Use Mermaid for service and resource maps, and PlantUML for component contracts, deployment views, C4 baselines, and formal architecture documentation.
Compare Mermaid and PlantUML for composite states, concurrent regions, history states, and entry or exit points in production state-machine documentation.
Compare Mermaid Flowchart and PlantUML activity syntax for branches, loops, fork/join, and early exits. Learn why formal activity models favor PlantUML.
Mermaid C4 remains experimental as of July 22, 2026. Compare its five views, documented limits, formal architecture fit, and governance with C4-PlantUML.
Compare Mermaid and PlantUML class diagrams for relationships, namespaces, association classes, view trimming, and maintainable formal UML documentation.
OnUML uses Mermaid 11.6.0, where subgraph only approximates lanes. Compare it with 11.16.0 swimlane-beta and PlantUML activity swimlanes for role ownership.
Mermaid covers six common control fragments. PlantUML adds dedicated return, autoactivation, reference, and pagination syntax for complex interaction flows.
Choose Mermaid for everyday documentation and PlantUML for formal UML or complex architecture. Compare capabilities, version limits, and delivery scenarios.
Learn Mermaid flowchart syntax with practical examples for authentication, CI/CD, microservices, error handling, SSO, and e-commerce workflows.
