Answer
DTOs abstract the API layer from database schema changes.
DTOs (Data Transfer Objects) act as a bridge between the database and the API, allowing developers to modify the database schema without impacting APIs. This decoupling is crucial for maintaining API stability and scalability. For example, if an e-commerce store's product price is stored in cents in the database but needs to be displayed in dollars to the client, a DTO can handle this conversion, allowing the backend to change without affecting the client interface.
