MVC - In Details
- 2. History Model–view–controller (MVC) is a software design pattern for implementing user interfaces on computers. It divides a given software application into three interconnected parts, so as to separate internal representations of information from the ways that information is presented to or accepted from the user. Traditionally used for desktop graphical user interfaces (GUIs), this architecture has become popular for designing web applications and even mobile, desktop and other clients.

- 4. HOW IT WORKS
- 5. CONTROLLER • The controller receives user input and makes calls to model objects and the view to perform appropriate actions. • A controller can send commands to the model to update the model's state (e.g., editing a document). It can also send commands to its associated view to change the view's presentation of the model (e.g., scrolling through a document). • Controllers act as an interface between Model and View components
- 6. MODEL • A model stores data that is retrieved according to commands from the controller and displayed in the view. • The Model component corresponds to all the data related logic that the user works with. • The model manages fundamental behaviors and data of the application. • This could be a database, or any number of data structures or storage systems. In short, it is the data and data-management of the application.
- 7. VIEW • A view generates new output to the user based on changes in the model. • The View component is used for all the UI logic of the application • The view effectively provides the user interface element of the application. It'll render data from the model into a form that is suitable for the user interface.
