Why use Flex

• Rich User Experience
  Applications developed using Flex ensure rich user experience through intuitive interaction with the application and presenting information in a visually rich interface. The end compiled output is Flash which is the most ubiquitous client software worldwide.

  Flex allows development of applications that support complex business logic to run at the browser, rendering a feeling of “quick response” and no refresh.
  
  
• High Performance
  The highly evolved client environment of Flex allows the applications to process large amount of information at client-end without any noticeable change in performance of the applications. This is in contrast to conventional DHTML applications which routinely crash if the record set is scaled up.

How Flex Works

Flex Development Environment
Flex IDE is developed on Eclipse and can be used as a stand-alone Integrated Development Environment. Flex IDE offers powerful features that include rich editors, a versatile debugger and in-built objects.

Data Services

These enable efficient transfer of information for seamless integration with preexisting applications that run from a common environment.

Application Framework

Flex Application Framework consists of the following components:

1. ActionScript
2. MXML
3. Class Library

ActionScript is used by developers to run client-side scripts that control the application’s behavior at client end. ActionScript is a derivative of Javascript.

MXML is used manage the objects that constitute the interface of the applications.

Class Library consists of service components. The most remarkable feature of these components is that along with in-built components, Flex also allows developers to create custom components.
