# Skill Gamma

Database operations skill.

## When to use

- User wants help with PostgreSQL
- Schema design questions
- Database migration workflows

## Workflow

1. Understand the schema
2. Write queries
3. Test with sample data

## Query Patterns

### Select with joins

```sql
SELECT u.name, o.total
FROM users u
JOIN orders o ON u.id = o.user_id
WHERE o.status = 'completed';
```

## Best Practices

- Use parameterized queries
- Add indexes for frequent queries
- Normalize to 3NF unless performance requires denormalization
