Typical Flow

design → sql → migrate → seed
         ↓
       optimize
         ↓
        erd

1. design users — plan fields and relations
2. sql users — generate executable SQL
3. migrate users — versioned migration
4. seed users — populate test data
5. optimize users — check index suggestions

Supported Databases

• Relational: MySQL, PostgreSQL, SQLite
• NoSQL: MongoDB, Redis (via nosql command)
