Individual skill

data-schema-design

Produces a relational or dimensional data schema with entities, attributes, data types, keys, relationships, normalization decisions with rationale, and a schema diagram description. Outputs a complete schema specification ready for implementation. Use when the user asks to design a database schema, define tables and relationships, model data entities, or plan a data structure for a new system or analytics layer. Do NOT use for data warehouse star/snowflake design (use data-warehouse-design), ETL pipeline logic (use etl-pipeline-design), or application code database migrations (that is software engineering).
