Questions tagged [model-view-controller]

Model–View–Controller (MVC) is an architectural pattern, introduced in mid 1970-s in PARC into how to compose software interfacing also with user-interactions. For Microsoft ASP.NET MVC, please use [asp.net-mvc] or [asp.net-core-mvc] tag instead. For Spring MVC, please use [spring-mvc] tag instead.

Model–View–Controller (MVC) is an architectural pattern used in software engineering, since Palo Alto Research Centre released one such in mid 1970-ies, designed in Smalltalk-79 language.

The pattern isolates "domain logic" (the application logic for the user) from the user interface (input and presentation), permitting independent development, testing, portability and maintenance of each (separation of concerns).

Reference

The analogy

MVC can be metaphorically related to a TV. You have various channels, with different information on them supplied by your cable provider (the model). The TV screen displays these channels to you (the view). You pressing the buttons on the remote controls affects what you see and how you see it (the controller).

Differentiating between domain, model, and entity with respect to MVC

Can someone explain these 3 concepts and the differences between them with respect to an MVC framework along with an example. To me these appear almost equivalent, and it seems they are used interchangeably in some articles and not in others.
