## Also known as

* Ports and Adapters
|
|
* Clean Architecture
|
|
* Onion Architecture

|
## Intent
|
|
Allow an application to equally be driven by users, programs, automated test or batch scripts, and to be developed and tested in isolation from its eventual run-time devices and databases.

|
|
* When it is important that the application highly maintainable and fully testable
|
|
