▸ 精选理由

快速可视化数据模型与主外键、基数关系。

这个 Skill 做什么

从需求或 schema 生成 PlantUML 实体关系图（ERD）。

根据需求描述、schema、SQL 或 ORM 模型生成 PlantUML 格式的实体关系图（ERD），把实体/表、属性/列、主键(PK)、外键(FK)和基数(cardinality)都画清楚。用于设计持久化数据结构、确认身份与引用关系时用，不用于建模运行时组件或类继承。特别之处是支持概念/逻辑/物理三个层次，并只建模数据相关的语义。

▸ 展开 SKILL.md 英文原文

Generate and refine entity-relationship diagrams (DER/ERD) in PlantUML from data requirements, schemas, SQL, ORM models, or architecture notes. Use for entidades, tablas, attributes, primary and foreign keys, identifying relationships, optionality, and cardinalities. Do not model software components, runtime deployment, class methods/inheritance, or temporal message flows.

# PlantUML Entity-Relationship Diagram

Model persistent data structure, identity, references, and cardinality.

## Workflow

1. Choose conceptual, logical, or physical data level and state it.
2. Extract entities/tables, attributes/columns, identifiers, and relationships.
3. Mark PK, FK, and unique constraints only when supported.
4. Determine minimum and maximum cardinality independently on both ends.
5. Resolve many-to-many relationships with an associative entity only for a
   logical/physical model or when the source defines it.
6. Apply [conventions.md](references/conventions.md).
   Apply [LANG-001 and LANG-002](references/language.md) to every user-visible
   label and response field
