B is for Binding

Flex Data Binding enables objects and their values to be bound together so that when a source changes a target automatically gets updated.

Data binding players:

• Source - the object/value we are interested in observing
• Target - the object/value we going to copy the source value to
• Trigger - the event from the source that triggers the copy from source to target
