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

使用規範化、關係和約束來設計數據庫模式。在為 PostgreSQL 和 MySQL 創建新的數據庫模式、設計表或規劃數據模型時使用。 來源：aj-geddes/useful-ai-prompts。
