## Intent
Pass data with multiple attributes in one shot from client to server, to avoid multiple calls to
remote server.
## Explanation
Real world example
> We need to fetch information about customers from remote database. Instead of querying the
> attributes one at a time, we use DTOs to transfer all the relevant attributes in a single shot.
In plain words
> Using DTO relevant information can be fetched with a single backend query.
Wikipedia says
> In the field of programming a data transfer object (DTO) is an object that carries data between
> processes. The motivation for its use is that communication between processes is usually done
> resorting to remote interfaces (e.g. web services), where each call is an expensive operation.
> Because the majority of the cost of each call is related to the round-trip time between the client
> and the server, one way of reducing the number of calls is to use an object (the DTO) that
> aggregates the data that would have been transferred by the several calls, but that is served by
> one call only.
## Class diagram
![alt text](./etc/dto-enum-uml.png "data-transfer-object")
## Applicability
Use the Data Transfer Object pattern when:
* The client is asking for multiple information. And the information is related.
* When you want to boost the performance to get resources.
* You want reduced number of remote calls.
