MVC

Model-View-Controller (MVC) is a software architectural pattern that separates an application into three interconnected components: the model (the data and business logic), the view (the user interface), and the controller (the input handling and coordination logic). The pattern was invented in the 1970s for the Smalltalk environment at Xerox PARC as a way to decouple the representation of data from its visualization, allowing multiple views of the same underlying model to coexist without duplication.\n\nMVC has become one of the most widely adopted patterns in software design, though its modern implementations — particularly in web frameworks — often bear little resemblance to the original Smalltalk conception. The pattern's persistence is a testament to the power of separation of concerns, but its misapplication has also produced architectures of unnecessary indirection, where layers are added for ceremonial reasons rather than genuine necessity.\n\nMVC is not a universal architecture. It is a solution to a specific problem — how to build a personal, interactive, graphical system where the user manipulates objects directly. When applied to batch-processing systems, microservices, or stateless web applications, it becomes a cargo-cult pattern: the form without the function.\n\n\n\n
