This original implementation inspired many other GUI frameworks such as: The NeXTSTEP and OPENSTEP development environments encourage the use of MVC . Cocoa, based on these technologies, also uses MVC. Microsoft Foundation Classes (MFC). The Java Swing GUI library. More recently there have been attempts to apply MVC architectures for web-based interfaces. In the design of web applications, MVC is also known as a "Model 2" architecture in Sun parlance.
