Introduction to Framework
4 | 12 Aug 2014
1. Introduction to Framework
“A Framework is a universal, reusable software platform to develop software applications, products and solutions. In other words, we can say it is some kind of library, a piece of software, which provide web developers with code base and consistent standardized ways of creating web applications”.

What is MVC?
7 | 12 Aug 2014
2. What is MVC?MVC is a software architecture - the structure of the system - that separates domain/application/business (whatever you prefer) logic from the rest of the user interface. It does this by separating the application into three parts: the model, the view, and the controller.
The controller receives user input and makes calls to model objects and the view to perform appropriate actions.
The model manages fundamental behaviors and data of the application.
The view effectively provides the user interface element of the application.
