BEST PRACTICES

Claude automatically applies:

1. Naming Conventions

   • Tables: snake_case, plural (users, order_items)
   • Columns: snake_case (created_at, user_id)
   • Indexes: idx_table_column

2. Common Patterns

   • Soft deletes (deleted_at)
   • Timestamps (created_at, updated_at)
   • UUID primary keys (optional)
   • Foreign key constraints

3. Performance

   • Index suggestions
   • Query optimization hints
   • Connection pooling setup

4. Security

   • Parameterized queries
   • Role-based access
   • Encryption for sensitive data
