Tutorials, guides, and best practices for UML diagramming
Explore copyable PlantUML examples for sequence, class, ER, C4, activity, component, and state diagrams, then learn how to style, save, and export them.
探索可复制的 PlantUML 时序图、类图、ER 图、C4 架构图、活动图、组件图和状态图示例，并学习如何设置样式、保存和导出。
Choose Mermaid for everyday documentation and PlantUML for formal UML or complex architecture. Compare capabilities, version limits, and delivery scenarios.
日常文档默认 Mermaid，正式 UML 与复杂架构图默认 PlantUML。通过交付物决策、能力矩阵与专项入口，选择适合团队的图表即代码工具。
Learn Mermaid flowchart syntax with practical examples for authentication, CI/CD, microservices, error handling, SSO, and e-commerce workflows.
Learn how to create beautiful sequence diagrams using Mermaid syntax. Covers basic syntax, advanced patterns, and best practices for API documentation.
Compare Mermaid and PlantUML class diagrams for relationships, namespaces, association classes, view trimming, and maintainable formal UML documentation.
基于 2026-07-22 官方语法核验，对比 Mermaid 与 PlantUML 的类关系、声明元素、关联类、视图裁剪、嵌套 namespace 与样式治理，给出正式 UML 类图的选型结论。
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.
区分 OnUML Mermaid 11.6.0 的 subgraph 分组与 11.16.0 swimlane-beta，说明为何角色职责和跨泳道交接默认选 PlantUML。
Mermaid covers six common control fragments. PlantUML adds dedicated return, autoactivation, reference, and pagination syntax for complex interaction flows.
Mermaid 支持 6 类控制片段；截至 2026-07-22，Mermaid 当前官方文档未提供返回、自动激活、引用与分页这些能力的等价专用语法，复杂调用栈优先 PlantUML。
