Design scalable, normalized database schemas with proper relationships, constraints, and data types. Includes normalization techniques, relationship patterns, and constraint strategies.

❌ Don't skip normalization for convenience ❌ Don't use VARCHAR(MAX) for all text fields ❌ Don't forget to add foreign key constraints ❌ Don't use natural keys as primary keys ❌ Don't store calculated values in base tables

✅ DO use UUIDs or sequences for primary keys ✅ DO normalize data appropriately ✅ DO add CHECK constraints for data validity ✅ DO create indexes on foreign keys ✅ DO use TIMESTAMP for audit trails

Design database schemas with normalization, relationships, and constraints. Use when creating new database schemas, designing tables, or planning data models for PostgreSQL and MySQL. Source: aj-geddes/useful-ai-prompts.
