The term rich Internet application (RIA) combines the
flexibility, responsiveness, and ease of use of desktop
applications with the broad reach of the web. Using
the broad reach of the Internet, RIAs can be deployed
across browsers and desktops.
Examples of RIA technologies includes
Curl,
GWT ,
Adobe Flash/Adobe Flex/AIR, Java/JavaFX,
uniPaaS,
Mozilla's XUL
Microsoft Silverlight.
Among the RIA technologies Adobe® Flash®
Platform is the leading solution for building rich
Internet applications, offering a complete set of
integrated technologies supported by an established
ecosystem.
The Adobe® Flash® Platform offers businesses and
developers a set of proven, flexible technologies for
rapidly building effective enterprise applications
that run across operating systems and browsers and
integrate easily with existing infrastructure.

These additional technologies can be used in combination with
the Adobe Flash Platform to build RIAs.
Adobe Flash Player
Adobe Flex® Builder™
The open source Adobe Flex framework
Adobe Flash Player software is installed on over 98% of
clients in enterprises (according to analyst reports), making
the Flash Platform the most consistent platform for
deploying enterprise applications.
Macromedia’s Flash 6+ is a multi-platform plug-in
installed in most Web browsers as well as an application
for developing content, interfaces, and applications. Flash
6+ supports rich vector-graphics, animation, and the ability
to build advanced web applications using scripting, forms,
XML, and server socket connections. Flash 5 has limited
support for some of these feature Sets.

Flex SDK provides features for accessing server-side
data. We can use Flex data access components to work
with three types of services:
HTTP (REST-style) Services
Web Services
Remote Object Services
Flex data access components are created in MXML or
ActionScript. These components are based on service
oriented architecture (SOA). These components use
remote procedure calls to interact with server
environments, such as PHP, Adobe ColdFusion, Java,
and Microsoft ASP.NET, to provide data to Flex
applications and send data to back-end data sources.

There are various Flex development frameworks
Cairngorm
PureMVC
Mate
Flight
Cairngorm (pronounced \kern-gorm\) is a
lightweight micro-architecture for Rich Internet
Applications for Flex or AIR applications. It is not
only a framework, but also an approach to
organizing and packaging code, components, and a
method to achieve separation of concerns (i.e.
Model-view-controller).
Compared to other frameworks, Cairngorm requires
the most components, but it is the most
straightforward.

There are two ways to integrate flex in AJAX application
1.
AJAX Bridge
The Flex Ajax Bridge (FABridge) is a small code library that you can
insert into an Flex application, a Flex component, or an empty SWF
file to expose it to scripting in the browser.
Rather than having to define new, simplified APIs to expose a graph
of ActionScript objects to JavaScript, with FABridge you can make
your ActionScript classes available to JavaScript without any
additional coding. After you insert the library, essentially anything
you can do with ActionScript, you can do with JavaScript.
2.
External Interface
The ExternalInterface class enables communication between
ActionScript and Flash Player containers such as an HTML page
containing JavaScript and an embedded SWF file, or an
application that has the Flash Player embedded in it. The
communication is available in both directions. An HTTP/JavaScript
page can call an ActionScript function which can return data that the
JavaScript can use or ActionScript can call JavaScript.
ActionScript can call any JavaScript function passing arguments and
receiving a return value from the JavaScript function. JavaScript on
the HTML page can easily call an ActionScript function complete
with arguments and return values.
