Frequently asked questions

When should I choose SQL over NoSQL?

Choose SQL when your data has structured, highly relational relationships and requires strict ACID compliance. Choose NoSQL for flexible, document-heavy, or rapidly evolving schemas.

Does this planner generate migration scripts?

This planner generates structural DDL blueprints and entity relationship definitions ready for adaptation into ORM models.
