data-model-creation

SKILL.md

Advanced data modeling tool for complex multi-table schemas with automated relationship management and ER diagram generation.

Designed for enterprise-level scenarios requiring multi-entity relationships, foreign key automation, and visual documentation; most simple table creation should use relational-database-tool directly with SQL

Generates Mermaid class diagrams following strict type mapping, naming conventions, and constraint rules for consistent schema design

Supports required/unique field constraints, default values, enum types, and display field definitions within the model structure

Includes business analysis, Mermaid modeling, and validation phases to ensure completeness and correctness before database implementation

Data Model Creation

Activation Contract

Use this first when

The user explicitly wants Mermaid classDiagram modeling.

The task needs complex multi-entity relational design, visual ER-style output, or generated data-model structure rather than direct SQL.

You need to create CloudBase data models through the dedicated modeling tools, or you need to inspect an existing model before planning follow-up changes.
