Hello! This week, we’re talking MVC and all that it entails…
MVC is popular in both App and Web development and is, undoubtedly, one of the most widely used software design patterns in development! MVC is popular with some huge national and international brands – think the likes of GitHub, Shopify, Instagram and Airbnb.
Importantly though, how can the MVC framework be incredibly useful for your business, or be something that you should look for ‘experience-wise‘ in prospective candidates?
At EDIT, we’ve taken some notes on the MVC framework and why this could be something worth adopting for your organisation or to develop skill-set wise if you’re a budding developer.
Why are developers using MVC?
Before 1990, it was not so important to create applications with specific architecture. Since then, applications are becoming increasingly complex each and every day, with innovative protection needed from new threats that could potentially exploit an application.
Also, the world of programming is getting bigger (and better!) day by day. Smart people are inventing new ways to create applications that can help us create them faster and easier than ever before. This one such architecture, MVC, was invented in the 1970s by Trygve Reenskaug, but was not actually accepted as a general concept till 1988. MVC is now widely used in modern web applications.
In this article, we will learn all about MVC. We will learn its advantages and its disadvantages. We will also learn how to work with an application created in MVC architecture, and also which frameworks are available in the programming language.
First of all, let us learn what MVC is, shall we…
So, what is MVC Framework?
MVC stands for Model-View-Controller. It is an architectural design pattern that makes creating huge applications just that little bit easier. MVC does not belong to a specific programming language or framework, but it is a concept that you can use in creating any kind of application or software in any programming language.
The MVC separates an application into three main logical components Model, View, and Controller. Hence the abbreviation MVC.
- (M) Model: It includes all the data and its related logic
The Model component stores data and its related logic. It represents data that is being transferred between controller components or any other related business logic. For example, a Controller object will retrieve the customer info from the database. It manipulates data and sends back to the database or uses it to render the same data.
It responds to the request from the views and also responds to instructions from the controller to update itself. It is also the lowest level of the pattern which is responsible for maintaining data.
- (V) View: Present data to the user or handles user interaction
A View is that part of the application that represents the presentation of data.
Views are created by the data collected from the model data. A view requests the model to give information so that it resents the output presentation to the user.
The view also represents the data from charts, diagrams, and tables. For example, any customer view will include all the UI components like text boxes, dropdowns, etc.
- (C) Controller: An interface between Model and View components
The Controller is that part of the application that handles the user interaction. The controller interprets the mouse and keyboard inputs from the user, informing the model and the view to change as appropriate.
A Controller sends commands to the model to update its state (e.g. saving a specific document). The controller also sends commands to its associated view to change the view’s presentation (for example, scrolling a particular document).
Here is how MVC architecture works in an easy to understand illustration.
MVC is a design pattern used to decouple user-interface (View) data, (Model), and application logic (Controller). This pattern helps to achieve separation of concerns.
When using this pattern for websites, requests are routed to a Controller that is responsible for working with the Model to perform actions and/or retrieve the data. The Controller chooses the View to display and provides it with the Model. The View renders the final page, based on the date in the Model.
If you are developing an application in PHP, you can use frameworks like Laravel or Codeigniter that uses MVC architecture to help you develop applications, fast and simply.
Importantly, what are the pros & cons of the popular framework, MVC?
Advantages of MVC architecture:
- Development of the application becomes fast.
- Easy for multiple developers to collaborate and work together.
- Easier to Update the application.
- Easier to Debug as we have multiple levels properly written in the application.
Disadvantages of MVC architecture:
- The complexity is high
- Must have strict rules on methods.
- Not suitable for small applications
MVC web frameworks:
- Ruby on Rails
- Spring MVC
- Zend Framework
The MVC framework is undoubtedly hard to understand – although, definitely not impossible! Developers should keep in mind that the architecture divides software into smaller components, aiding and simplifying the development process.
