Flex is based on AIR application approach where application preferences are saved at the user level by applying build-in classes, application not necessarily connects to Internet .
Flex builds RIA (Rich Internet Applications)
Open-source development framework
Based on two languages: 1)XML-based language MXML , 2) object-oriented scripting programming language ActionScript 3 is based on JavaScript.
Compiled
Cross-platform using AIR/ cross-browser applications using Flash Player
Flex pulls data from the server with an HTTP request by accessing XML files that can be stored on a web server. It can be done even for the mainframe servers!

Flex application process flow:
• Client invokes application
• Flex compiles MXML/ActionScript file into all ActionScript, then
creates a SWF
SWF is cached
■ If file already requested, cached SWF is delivered
• Compiled application SWF downloaded to client
• Application requests additional resources using HTTP, SOAP or AMF
