| 1 | This is because loose coupling is not appropriate at all levels of application design. | |
| 2 | This list leaves out the most important aspect of loose coupling: ubiquity. | |
| 3 | Some solutions offer this component but it is tightly coupled with the presentation layer. | |
| 4 | These patterns both extract behavior out of the view and into a presentation class coupled with the view. | |
| 5 | The best practice is to avoid tight coupling of the service interface and schemas to the underlying implementation and technology. |
