Can\'t we just keep ou

Answer 1

Perhaps this is just a linguistic thing. I've seen "frameworks" referring to themselves as a DSL -- Domain Specific Language.

And you don't need a framework But here's something to consider: You already know for a web app you're going to want to do a few common things... route URLs, render pages, etc. Why re-write it all? For other problem domains you'll have generic things to do as well.

Model View Controller or MVC as it is popularly called, is a software design
pattern for developing web applications. A Model View Controller pattern is made 
up of the following three parts:

**Model** - The lowest level of the pattern which is responsible for maintaining data.

**View** - This is responsible for displaying all or a portion of the data to the user.

**Controller** - Software Code that controls the interactions between the Model and View

Answer 3

An MVC framework is a framework written to split up the the business logic, database access and presentation.

This is very useful in most web applications, and now lately into software/desktop applications.

This is due to the fact that following the MVC model, your code will be much clearer, cleaner and you keep your application DRY (Do not Repeat Yourself).

You can write your own classes and separate them into Model, View and Control. But again, you will need a framework to help you in accomplishing certain tasks. Like a List control in ASP.NET, or PHP framework being able to help you translate text between languages and so on. (Oh why reinvent the wheel?!)
