Should a DTO be serializable?
There’s no requirement for them to be serializable. DTOs are anemic in general and do not contain any business logic. DTOs are often java.
Is DTO a good pattern?
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. Another use for DTOs can be to encapsulate parameters for method calls. This can be useful if a method takes more than four or five parameters.
Can a DTO have methods?
A DTOs Structure. Data Transfer Objects are public (static) classes with no methods, other than the compiler supplied default constructor, having only public fields limited to the easily serializable types: i.e. A DTO is equivalent to a struct in C.

Can a DTO be created from a domain object?
The domain object contains no reference to the DTO. An outside entity (a “mapper” or “assembler”) is called to create a DTO from a Domain Object. Normally there is an ORM on the domain object side. The downside of this is that the “mapper” tends to get extremely complex for any real situation and can be very fragile.
Why are data transfer objects ( DTOs ) an anti-pattern?
If you’re not build a distributed system, chances are you don’t need them. DTO becomes a necessity and not an ANTI-PATTERN when you have all your domain objects load associated objects EAGERly. If you don’t make DTOs, you will have unnecessary transferred objects from your business layer to your client/web layer.
What’s the point of using a DTO in Java?
DTO was clearly defined as a solution for a distribution problem. DTO was meant to be a coarse-grained data container which efficiently transports data between processes (tiers). ~ Adam Bien DTOs are called Data Transfer Objects because their whole purpose is to shift data in expensive remote calls.
When do we think of DTOs as view models?
Ah, the DTO (Data Transfer Object). Data Transfer Objects are a (fancy) term for an object that carries data between two separate systems. When we’re concerned with web development, we think of DTOs as View Models because they’re faux models.
