I'd extend the docs to contain an example for e.g. an API response based DTO so our users know, that DTO's can also be used outside of the ORM/Table ecosystem. |

| Transfer Objects (DTOs) instead of Entity objects. DTOs provide a | ||

There was a problem hiding this comment.

- Highlight advantages over arrays (type safety, IDE support, decoupled serialization) - Add API response example showing DTOs used outside ORM context
