Dataprovider for Flex Tree

Question

how do you dynamically populate nodes in the Flex tree with data from a database?
For example... if I have a node for Groups and a database for names of groups... how would I populate the child nodes of the Groups folder with the names of the groups in the database?

alright i'll experiment. you may be able to help me understand why this isn't working though... this is the route i was going down:
i wanted to convert this mxml to actionscript and bind it to the tree (so i can add results from my dataprovider):
    <mx:XMLListCollection id="treeData">
        <mx:source>
      <mx:XMLList>
              <node label="Items">
                  <node label="Open"/>
                  <node label="In Progress"/>
              </node>
      </mx:XMLList>
        </mx:source>
    </mx:XMLListCollection>
and i was trying this code to make it bindable:
var stringData:String = '<node label="Items">' + '<node label="Open"/>' + '<node label="In Progress"/>'
+ '</node>';
var treeData= new XMLList(stringData);
but when i use actionscript to create the treeData variable... and use {treeData} as the binding data... nothing shows in my tree.
