What is Model-View-Controller (MVC) Architecture?
Model-View-Controller architecture is all about dividing application components into three different categories Model, View and the Controller. Components of the MVC architecture have unique responsibility and each component is independent of the other component. Changes in one component will have no or less impact on other component. Responsibilities of the components are: Model: Model is responsible for providing the data from the database and saving the data into the data store. All the business logic is implemented in the Model. Data entered by the user through View are check in the model before saving into the database. Data access, Data validation and the data saving logic are part of Model. View: View represents the user view of the application and is responsible for taking the input from the user, dispatching the request to the controller and then receiving response from the controller and displaying the result to the user.

The MVC paradigm (design pattern) is a way of breaking an application, or even just a piece of an application’s interface, into three parts: the model, the view, and the controller. MVC was originally developed to map the traditional input, processing, output roles into the GUI realm: Input –> Processing –> Output Controller –> Model –> View The user input, the modeling of the external world, and the visual feedback to the user are separated and handled by model, viewport and controller objects. The controller interprets mouse and keyboard inputs from the user and maps these user actions into commands that are sent to the model and/or viewport to effect the appropriate change. The model manages one or more data elements, responds to queries about its state, and responds to instructions to change state. The viewport manages a rectangular area of the display and is responsible for presenting data to the user through a combination of graphics and text. Separating responsibilities amon
