Needless to say, Model View Controller or MVC is a widely-used model in the web development landscape since a long time now. MVC pattern is quite popular among various major programming languages like Java, Python, Ruby, PHP. However this pattern is largely used for enterprise grade web application development purposes on the ASP.NET platform.
ASP.NET is undoubtedly the strongest contender when it comes to building web applications using the MVC pattern. In this pattern, the Model represents the application core, the View displays the data and the Controller handles the input.
This unique type of MVC separation allows ease management of the complex applications allowing developers to focus on one aspect at a time.
Why should you follow MVC architecture?
There has to be a strong reason behind why a majority of developers and entrepreneurs prefer the MVC architecture. Ask any reputed MVC development company and they will give you countless reasons as to how significantly this pattern has eased out the development process.
First thing is, with the separation of the use of code between the three file types, a developer can easily divide web application logic. It gives you complete separation in programming logic and the interface code, along with the separation in the type of logical code for the web application you want to build.
Web apps that follow MVC structure split the three kinds of functionality into three types of files: models, views, and controllers.This functionality allows you to design, implement, and test each portion separately and still keep the code organized and neatly structured. You can find anything quickly when it is needed the most, test features easily, and add functionality with ease.
It makes your code more efficient in a way where you can even reuse the code to make the applications faster than ever.
The Model
Model is responsible for working directly with the database and it does not have to deal with user interface or data processing. While developing web applications, developers will simply use the model to fetch, insert, update and delete data from the database.
For instance, if you are constructing a task management application that allows users to organise tasks based on date and time, it means that It means that users and tasks will be managed in the database. In the language of MVC, User and Task are models in the application.
Hence a developer will create two models in the application named User and Task. It is important to note that models also have relationships with each other. In thisn scenario, every task belongs to a specific user, and a user might have multiple tasks. The process is to implement one method in the User model to fetch all the user’s tasks and implement another method in the Task model that will fetch a user.
The View
Put simply, View is the User Interface where customers and users can perform specified actions. It contains HTML,CSS,JS, XML or any other markup language that can be used to create a beautiful and tidy user interface. It also has code to show the data that it receives from the application.
There are two actions a View has to perform and they are i) show data to the customer/user on User Interface and ii) to respond to the events. If one user clicks on Update or Delete button, for instance, he should be redirected to the Update form or to the delete confirmation popup.
The Controller
This is the most fascinating part of the MVC architecture. Controller is the part where the data is processed after you get a request from View and before updating anything in the database with the Model.
Take into account the homepage of an application that you are building. It prompts the user to enter three tasks that he wants to manage in the application. Once he enters those three tasks, he is redirected to the registration form along with these three tasks. And after registration, those three tasks appear in the dashboard.
The Controller makes it easier for developers to manage such scenarios. This is possible since the Controller contains the functions that can be programmed the way you want. Here is another example, after you receive the data in the UserController in the Store method, you will simply create a user account. After creating a user account, check if there are any tasks that a user has submitted along with the name and email.
If a user has submitted the tasks, create the user’s tasks before returning the “Registration successful” message to the Register view.
In the task management application, you have two controllers named UserController and TaskController. Controllers contain the methods like Create, Update, Destroy, Store and Show. If a user accesses the Index or Show or Update view, it will simply fetch the data from the Model and return it to the View in a variable.
Conclusion
A pattern like this provides full control and authority over the application, making sure that it runs with clockwork precision. And when it comes to large enterprises, even a small glitch can turn out to be costly. This is exactly why MVC architecture wins over the others a majority number of times.
