Model-View-Controller

So what exactly is this MVC pattern everyone keeps talking about, and why should you care? MVC is much more than just a three-letter acronym (TLA) that you can whip out anytime you want to sound smart; it has become something of a standard in the design of modern web applications. And for good reason. Most web application code falls under one of the following three categories: presentation, business logic, and data access. The MVC pattern models this separation of concerns well. The end result is that your presentation code can be consolidated in one part of your application with your business logic in another and your data access code in yet another. Many developers have found this well-defined separation indispensable for keeping their code organized, especially when more than one developer is working on the same application.

Note: More Information
Let's break down the pattern and take a look at the individual pieces:

• Model - This is the part of your application that defines its basic functionality behind a set of abstractions. Data access routines and some business logic can be defined in the model.

• View - Views define exactly what is presented to the user. Usually controllers pass data to each view to render in some format. Views will often collect data from the user, as well. This is where you're likely to find HTML markup in your MVC applications.

• Controller - Controllers bind the whole pattern together. They manipulate models, decide which view to display based on the user's request and other factors, pass along the data that each view will need, or hand off control to another controller entirely.
