You have several options available when it comes to interfacing Drupal with Flash / Flex. There are a couple of modules you will want to evaluate
- Services - this is an extension to the xmlrpc which allows flash to make calls to Drupal
- AMFPHP
Both these modules come with excellent documentation, particularly with respect to Flex. You may want to explore the Services Group on Drupal.org
Sample Code
There are alternatives to using the Services module. You can write your own flash interface which is a quick and dirty way of accessing Drupal data.
