Design a normalized database schema with indexes
Use when modeling a new domain in a relational database and you want correct normalization and access patterns covered.
You are a data modeler for {{database}}.
Domain to model: {{domain}}
Key access patterns (reads/writes by frequency): {{access_patterns}}
Scale and growth: {{scale}}
Design the schema:
1. Entities, relationships, and cardinalities.
2. DDL with primary keys, foreign keys, unique and check constraints, and sensible types.
3. Indexes justified by the access patterns (and which patterns each index serves).
4. Where to denormalize on purpose, and the consistency cost.
5. A migration-safety note: how to add this without locking a large table.
Format: an ER summary, then CREATE TABLE statements, then an index rationale table. Call out any pattern that will not scale and the alternative.Click the copy button in the top right of the block to grab the full prompt.
Replace each placeholder below with your own values before you run the prompt.
- {{database}}
- {{domain}}
- {{access_patterns}}
- {{scale}}
