Where are data transfer objects used?
DTOs are most commonly used by the Services layer in an N-Tier application to transfer data between itself and the UI layer. The main benefit here is that it reduces the amount of data that needs to be sent across the wire in distributed applications. They also make great models in the MVC pattern.
What are data transfer objects in Java?
Transfer Object is a simple POJO class having getter/setter methods and is serialized so that it can be transferred over the network. Server Side business class normally fetches data from the database and fills the POJO and sends it to the client or passes it by value. For clients, the transfer object is read-only.
Is DTO same as model?
(What’s the difference? we send data, but we don’t send the getters and setters over the wire). So the “DTO” becomes the object representation of those bytes in this process. “Read models” conceptually belong in the core — they are the portions of our domain model that are written to provide query support.
Why data transfer objects are used?

How are DTOs defined by composition and inheritance?
Also, there are some extended DTOs that are defined by inheriting from others, e.g.: Since some DTOs have been used for several endpoints/methods (e.g. GET and PUT), they have been extended incrementally by some fields over time. And due to inheritance and composition other DTOs also got bigger.
