What does the acronym MVC stand for in the context of Rails?
回答
MVC stands for Model-View-Controller, an architectural pattern that separates the application into three interconnected components. The Model handles data and business logic, the View displays the user interface, and the Controller orchestrates interactions between the two. This separation facilitates code maintenance and testing.
