Microarchitectures are groups of design patterns prepared to work together in concert. PureMVC represents a leading alternative to the well-known Cairngorm framework. PureMVC is a light framework for creating applications based on the class Model-View-Controller meta designpattern. It has a very narrow goal, to provide design patterns AND development patterns to help you separate your programming into three distinct areas; data, user interface, and the application logic. It is approachable and powerful with minimal tedium and repetition in development.
