The MVC Connection
In general a visual component is a composition of three distinct aspects:
- The way that a particular component looks when rendered on screen
- The way that a particular component reacts to an user
- The state information which is associated with a particular component
No matter what the architecture used to implement a particular component it must implicitly contain the three parts i.e. Model-View-Controller or MVC for short.
In the MVC terminology we have ,
- Model:
the Model corresponds to the state information which is associated with a component. For example-in case of a check box, the model contains a field which indicates whether the box is checked or unchecked.
- View:
The view determines how a component has displayed on the screen, including any aspects of view that are affected by the current state of the model.
- Controller:
The controller determines how the component will react to the user.
For example, when user clicks a check box, the controller will reacts by changing model to reflect the user’s choice (checked or unchecked) which then results in the view being updated.
