Architectural patterns

The user interface of an application can be described as the packaging over the sum of all the moving parts underneath. As applications get more complex, the responsibilities of the user interface increase and it gets harder to package the product underneath. Leaving aside the static parts of the UI (that is, assets described in the previous sections of this chapter), it is the most volatile part of an application. In order to counteract the entropy that builds up throughout the application's lifetime, solve recurring problem patterns, and re-use modules, developers often utilize certain design patterns in their development efforts. Especially in cross-platform projects, the importance of these architectural design patterns have been proven to be irrefutable.

For demonstration purposes, let's use a simple form-submit scenario. In this implementation, the users will be greeted with a form they will have to fill in. Once all the required text fields are populated by the...
