Java: DTOs and Entities
Answer
DTOs add a layer of abstraction between the API and persistence layer.
Using DTOs introduces a design layer that separates the API's data representation from the database schema. This abstraction allows for changes in the database without affecting the API, facilitating easier maintenance and evolution of both layers. For example, you can change the underlying database fields of a `Product` entity without altering the `ProductDTO` used in the API.
