4 Advanced MVC

Until now, the main focus was on the basic patterns of MVC. In this chapter, we will observe the broader picture of a MVC application and how the patterns interact with the real world. We will analyse the following:

• Additional layers often found in UI applications: Service and IO.
• Advanced patterns required for Models and Notification strategies
• Common problems encountered during MVC development.
• Interactions with multithreaded programming, asynchronous programming and the event loop
• Techniques for debugging and testing of MVC applications

Additionally you might have to fight your toolkit because it prefers a specific implementation of MVC.
