Railes uses the Model-View-Controller or MVC architecture like many current web frameworks for organizing application programming. MVC in general is an architectural pattern favorably used in software engineering where the application becomes easier and less complex to modify and adjust either the visual appearance of the application or the fundamental business rules without affecting the other. Complicated web applications are indeed more difficult to design than conventional applications but with the help of MVC, it becomes a potential answer to these complexities. In MVC, the View matches up to elements of the user interface such as text, checkbox items and so on. While the Model characterizes the data of the application and other; the View corresponds to elements of the user interface such as text, checkbox items, etc. And it’s up to the Controller to direct details concerning the communication to the model of user actions like the keystrokes and mouse movements.
