Model-View-Controller (MVC)
subject			fact

Model-View-Controller	has definition A architectural pattern used to separate the functional layer of the system (the model) from two aspects of the user interface, the view and the controller
	facilitates divide-and-conquer because the three components can be independently designed
	increases cohesion because the components have stronger layer cohesion than if the view and controller were together in a single UI layer
	increases flexibility because it is usually quite easy to change the UI by changing the view, the controller, or both
	increases layer cohesion of the user interface layer
	increases reuse because the view and controller normally make extensive use of reusable components for various kinds of UI controls
	is a subtopic of 9.5 - Architectural Patterns
	is abbreviated as MVC
	is related to the multi-layer architecture
	is a kind of software architecture
	reduces coupling because the communication channels between the three components are minimal and easy to find
	reduces the coupling between the user interface layer and the rest of the system, as well as between different aspects of the UI itself
	separates the functional layer of the system (the model) from two aspects of the user interface, the view and the controller
software architecture	constrains the overall efficiency, reusability and maintainability of the system
	is decided early in the design process, although it will continue to mature as iterative development proceeds
	must be understood by software engineers
	see also software architecture^2
	see also software architecture^3
pattern	should be as general as possible
	should be described in an easy-to-understand form so that people can determine when and how to use it
	should contain a solution that has been proven to effectively solve the problem in the indicated context
