What exactly is design pattern?

What exactly is design pattern? MVC is considering a design pattern?

First of all, what does MVC stand for in this context? Then, how is that a question? Can you rephrase that.

At the top of the list in a google search for "design patterns":

http://en.wikipedia.org/wiki/Design...mputer_science)

MVC is one of the design patterns.

This is a great site for learning design patterns or finding out which pattern(s) best suits a particular situation.

They describe in detail all of the GoF design patterns (pretty much the core of all design patterns) with code samples!

Hope it helps

A design pattern is a typical solution to a re-occuring problem essentially. A singleton would be an example, when you need a class that can only be instantiated once. The design pattern solution would try to explain a solution to this in a non language specific way.

This is the way i think of them typically.

For better knowledge on them O'reilly makes a really nice book or you could check out the de facto gang of four book that most of this stuff was created in.

It may be enlightening to know that MVC is an acronym for "Model View Controller" -- but I assume a Google search could tell you that.

If you're asking what a design pattern is, the actual gang of four book is probably going to be a bit over the head of the OP. Luckily, there are a lot of internet resources that succinctly summarize the important points and provide overviews of common design patterns.

As for what they ARE:
"Design patterns are recurring solutions to software design problems you find again and again in real-world application development. Patterns are about design and interaction of objects, as well as providing a communication platform concerning elegant, reusable solutions to commonly encountered programming challenges."
