Web MVC
The Model-View-Controller (MVC) architecture is a standard architecture for interactive applications. In client-server programming, the MVC components are distributed across at least two nodes of a network. This leads to a set of choices about where to deploy each component of the architecture. One solution is the traditional server-based MVC model. Another is the Rich Internet Application (RIA) model. In a real-world application with client-side validation, these are more similar than they might seem.
Desktop MVC
In an interactive application, there is typically a domain model,
code to present the model to the user, and code to act upon the model in
response to the user manipulation of input devices such as the keyboard
and mouse. For example, in a word processor the domain model is the
document, which contains entities such as paragraphs, spans, and styles.
The system presents the document to the user as (for a sighted user)
glyphs rendered as pixel patterns, and interprets keystrokes and mouse
actions as edit, formatting, and control commands.
Smalltalk-80 introduced the Model-View-Controller (MVC) architecture for structuring this type of application. MVC separates the maintainance of the domain model (the Model), the presentation of the model (the View), and the interpretation of user input (the Controller).
