Model–view–controller
Model–view–controller (MVC) is a software architectural 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.
