Best for

✓ Best for

Node.js developers who need to interact with multiple database types within the same application
Teams building scalable web applications requiring advanced query capabilities and associations
Projects where consistency in API across different storage adapters is crucial

✓ Best for

Developers building Node.js apps who prefer an ORM over raw SQL.
Projects requiring support for multiple database dialects without changing code.
Teams that need a robust set of features for managing complex queries and relationships.

Not ideal for
