We can simplify MVC into Model-View-Controller that is a well-known word in software engineering and web application development space. It’s a terminology or pattern that is applied in web development to separate 3 main pieces of any application into their isolated environments. Though, this was originally developed for the desktop computing but adopted widely in all programming languages as architecture for World Wide Web applications. MVC changed the whole scenario of internal representations of information. It changed the way the information is presented to or accepted from the user.
MVC pattern has become the most popular and powerful framework since it improves development process of websites, web services and interactive web applications. It can be applied to JAVA, PHP, ASP.NET and many other programming languages and also facilities customization in World Wide Web applications.
The Controller, the View and the Model are the three components of MVC that actually does everything within an application such as:
1. The Controller – In the web environment, the Controller plays a role of the traffic cop of the application. The Controller handles incoming HTTP request. It is also directing traffic to where it should go, identifying which view needs to load up and is interacting with the appropriate models.
2. The View – The View in a web-based application is the representation of the user-interface. Buttons, forms and other information visible to the user on the web are all part of View. View is implemented when controller calls up the view after having interaction with the appropriate model that gathers the particular information to display in a particular view.
3.The Model – the Model is a place where all data is stored regarding the application in separate models. This is the place where data from controller and sometimes the view is actually passed into, out of, and is manipulated. There is no link between Model and HTTP, web servers or anything like that but it is responsible to check the data against the stored information in database and then to supply it accordingly.
This is the basic concept of the MVC pattern. The separation between view and controller is very well defined in MVC that lets the programmers to work on web application with different business logic. A programmer is able to discriminate these very separate pieces of code into their own domain, that ensure code maintenance and debugging much easier rather than all items chunked into one massive piece.
This kind of web architecture allows the programmer to identify and tackle application related issues effortlessly. The separate nature of MVC makes it easier to manage complexity of large applications easily. It lets programmers to focus on one aspect of execution at a time. MVC architecture is also flexible that supports rapid and parallel development that ensures quick turnover of applications simultaneously maintaining high standard of quality for the application.
The increased productivity and maintainable code which MVC framework provides makes it widely used web application development tool.
