There are many ways to use MVC, and you certainly don't have to understand those other patterns first. Maybe how you use MVC. You can use simpler forms of MVC without those patterns. >> But I am trying to understand why you would go through all that trouble, >> when calling the function in the parent, if it is a very small application >> unlikely to be expanded upon, is so much simpler? Anthony - for very small applications, no, you wouldn't use a framework, and maybe not even a design pattern - perhaps just a simple one. You could call the funciton in the parent, sure, but know that it's not a good habit to get into, and will cause headaches in larger applications because you're doing what is known as tight coupling. Loose coupled architecture, when possible without over-coding an app, is the way to go in most projects. Event dispatching and event listening is simple to implement anyway IMO.

Enter chapters are shifted off the page but there are addendum on the site. Also, MVC's are made up Observer, Strategy, and Composite patterns. Those need to be understood first. @Anthony, >From what I've understood, if you aren't going to need to go back an edit/extend the app frequently or work on a team, there really isn't much benefit to using design patterns. They do however lend to re-using old classes in new apps so you that you don't have to start from scratch each time.
