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.
Use Mermaid Crow's Foot notation for application schemas and PlantUML Chen notation for conceptual models. Compare keys, cardinality, scope, and tradeoffs.
基于 2026-07-22 官方语法核验，对比 Mermaid 的 Crow’s Foot 与 PK/FK/UK 属性标记、PlantUML Information Engineering 和 Chen 概念模型，明确应用 ERD 选型。
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.
基于 2026-07-22 官方语法核验，对比 Mermaid 与 PlantUML 的普通状态流、复合状态边界、历史状态、进入/退出点和并行区域，给出正式状态机选型。
Compare Mermaid Flowchart and PlantUML activity syntax for branches, loops, fork/join, and early exits. Learn why formal activity models favor PlantUML.
聚焦 Mermaid Flowchart 与 PlantUML 活动图的开始结束、分支、循环、fork/join 和提前终止，说明正式活动图为何默认选 PlantUML。
Mermaid C4 remains experimental as of July 22, 2026. Compare its five views, documented limits, formal architecture fit, and governance with C4-PlantUML.
截至 2026-07-22，Mermaid C4 仍为 experimental，支持 5 类图却短期缺 sprite、tags、link、Legend；正式 C4 图优先 C4-PlantUML。
