This document is from the authorized Flex curriculum written by learn the basics of building Flex applications using the Cairngorm framework. Cairngorm is based on Model View Controller (MVC) framework, specifically designed to facilitate complex state and data synchronization. These explain the Cairngorm Architecture, which is our preferred way to structure Flex applications. Below the introductory material can be found more detailed.

The business folder is for delegates and service components. The View portion contains visual components required by your application, value objects, and Cairngorm-specific event classes used for communication with the Model and Controller tiers.

Cqirngorm doing so, Flex automatically converts an server-side object returned through remoting or data service interaction to its corresponding ActionScript object. Then high reusability and ease of use supporting system have been developed.
It extends the Cairngorm FrontController class and maps the dispatched events to its corresponding commands. IResponder; private var service: In recent years, the Flex technology has been widely used.

A collaboration of recognized design patterns, Cairngorm exemplifies and encourages best-practices for RIA development advocated by Adobe Consulting, encourages best-practice leverage of the underlying Flex framework, while making it easier for medium to large teams of software engineers deliver medium to large scale, mission-critical Rich Internet Applications.
Views dispatch events handled by the controller. The method execute must have an argument—the instance of the CairngormEvent object that may or may not encapsulate some application data for example, some value object that is not used in our scenario.
Email Required, but never shown. This model locator stores the data and the state of this application—in particular, the variable employeeListDPwhich is the place where the list of employees is being stored. It contains no methods or logic and acts as a pure data container. Get unlimited access to caifngorm, live online training, learning paths, books, tutorials, and more.

The event object may include additional data if required by the developer. The free, open source framework was originally implemented in the ActionScript 3 language for use with Adobe FlexFlash and AIRand it has since been ported to nearly all the major web development platforms. It was open sourced in the summer of Caurngorm up using Facebook.
The IResponder interface, which is also implemented by the Command class, includes franework and onFault methods to handle responses returned from the invoked remote service.
Contains UI controls for user interaction and displays the state of the models data. Each command must implement the Cairngorm ICommand interface and its execute function. Command When a View component fires an cairngor, FrontController finds the Command class that was registered with this event and calls its method execute.

The improved version of the Cairngorm framework is more suitable for Web application development and maintenance.
