MVC is the most popular architectural design pattern for building web applications in 2019. It is used by many popular frameworks. In this video I will explain what MVC is, how it works, and why you should use it in just 8 minutes.
MVC stands for Model, View, Controller. It is used to make building complex web applications easier and more organized.
The Controller handles user requests and delegates information between the Model and the View. It only deals with requests, and never handles data or presentation.
The Model handles data validation, logic, and persistence. It interacts directly with the database to handle the data.
The View handles presenting the information. It will usually render dynamic HTML pages based on the data the model fetches. The Controller is responsible for passing that data between the Model and View, so that the Model and View never have to interact with each other.
It is important to note that this concept or pattern is no strict and is altered in some frameworks. So be aware that there are variations of MVC.
