* added pumlid where it was missing and possible * removed pumlid where it generated a bad image * regenerated some incorrect puml's * added 'left to right direction' puml prefix to some diagrams to improve the automatic layouting

## 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.
|
|
|
|
|
|
|
|
## Applicability
|
|
Use Hexagonal Architecture pattern when
|
|
|
|
* When the application needs to be independent of any frameworks
|
|
* When it is important that the application highly maintainable and fully testable
|
|
