DTO is an acronym for Data Transfer Object, a design pattern used in data transfer.

DTO is an acronym for Data Transfer Object, a design pattern used in transferring data through internal or external interfaces. A DTO protects the application's internal data by acting as dummy storages, the whole logic is implemented only in actual Domain Objects (DO).

Pros:

  • Fewer remote calls (typically one, getDto() vs. individual getId(), getName(), etc.)
  • Improved data capsulation (Remote systems need only to know the details of the DTO, not DO internals)

Cons:

  • class explosion
  • conversions needed between DTOs and DOs
