About Flex and ColdFusion

The Flex Data Service assembler lets ColdFusion developers use ColdFusion components
(CFCs) to provide the back-end data management for a Flex application that uses the Data
Management Service.
To use the Flex Data Service assembler, the Flex application must be running on Flex
Data Services 2.0.
How ColdFusion and Flex interact
The Flex Data Management Service feature lets you configure a Data Management Service
destination, which is the server-side code that you connect to. To use the ColdFusion Data
Service adapter, you specify it in the destination in the Flex Data Service configuration file.
The Flex Data Management Service recognizes the methods:
which you include in your ColdFusion CFCs.
The following image shows the process that Flex and ColdFusion use when a Flex application
calls a method in a ColdFusion component.
