Understanding DTO (Data Transfer Object) Pattern in 4 Minutes

DTO (Data Transfer Object) Pattern is used to transfer the data between the client and server.

Data Transfer Object Design Pattern is a frequently used design pattern. It is basically used to pass data with multiple attributes in one shot from client to server, to avoid multiple calls to a remote server.

Another advantage of using DTOs on RESTful APIs written in Java (and on Spring Boot), is that they can help to hide implementation details of domain objects (JPA entities). Exposing entities through endpoints can become a security issue if we do not carefully handle what properties can be changed through what operations.

[lovemishra]

Now it is clear. Earlier I used to think DTO and Objects are same. Thanks .

Perfect explanation👌, your videos are helping me a lot in my project, I can’t wait for the microservices course.

1. Not manadatory to use dot 2. But rather that providing whole object ( containing all fields like id, name, …imp details ), we convert object to a dot with limited fields from object 3. We achieve security

[KhanhNguyen-gmhe]

So DTO has the same meaning as Model in MVC?

what is the difference between Facade design pattern DTO pattern?

[GodofStories]

I feel showing this in code would be much better

It's unclear to me, you have aggregated three API Calls into one and returning the response,

What if client wants to fetch only organisation data then what ?

Also in dto sent from client can we mention what data we want and server will process that request and return the only data which was requested by client
