What Is MVC And Why Should Coders Care?

If you are using ASP.NET MVC as your Web application framework (as so many do because it is open-source and great software), you will need to tackle practical issues like learning the best practices for ASP.NET MVC error handling (you can delve into the concept of ASP.NET MVC error handling by clicking on this excellent Stackify link).

But, you should also pause to gain a fuller appreciation and understanding of at least the basics of the software product you are putting to use. In that interest, we here present answers to the questions: ‘What is MVC?’ and ‘What are the benefits of using MVC?’.

What Is “MVC” In Computer Programming?

MVC is a software architecture pattern that assists you in creating user interfaces. The system consists of the three parts Model, View, and Controller (hence, “MVC”); and each of these components is integrated and yet “decoupled.” The overall structure results in the separation of “internal representation” and how data is presented in interaction with users.

At first, MVC was reserved for graphical user-interfaces, but today, it is used across a wide range of applications. Java, C-sharp, and other computer languages have their own MVC frameworks.

The three MVC components function like so:

  • The Model is the core component of MVC. It is the thinking machine behind and independent of the interface. The Model takes care of the internal app rules, logic, and critical data.
  • A View is any form of output to the user interface, and it will take on a different, easier to understand form than the internal presentations of data. Note that you can have two or more views of the same internal data.
  • The Controller is that which takes in input from users and transforms it into a view or into something the Model can process.

What Benefits Does MVC Offer the Developers?

The popularity of MVC, whether in ASP.NET MVC or elsewhere, stems from several key advantages it offers developers.

The first major benefit is simultaneous, parallel development. This means that more than one developer or development teams can simultaneously work on the decoupled parts of the app in parallel. One team, for example, can tackle the back end development, while another team hits the front end (user interface and layout). That obviously saves time and allows for more flexible project organization.

The ability to reuse code is also enhanced by MVC. This is due to the independence of components and to the ease with which such separated parts can be modified, if necessary, before being reused elsewhere.

MVC gives you “high programming cohesion” in that similar actions are grouped together logically and in that different views of the same model are also grouped. And the very fact you can have multiple views of one model is also a distinct advantage.

MVC code can be difficult for the novice to navigate due to its extra layers of abstraction, and there is definitely a little bit of a learning curve involved since it requires know-how across multiple tech niches to put to optimal use. But, overall, MVC is well worth learning and using because of its noteworthy advantages.
