Data binding is the process by which changes in ONE action script OBJECT are reflected in another action script object. (OR) Data binding automatically copies the VALUE of a property of a source object to a property of a destination object when the source property changes.

Data binding requires a source property, a destination property, and a triggering EVENT that indicates when to copy the data from the source to the destination. An object dispatches the triggering event when the source property changes
Adobe FLEX provides 3 ways to specify Data binding:

1. Curly braces ({ }) syntax in mxml and [Bindable] metadata tag
2. <mx: Binding> tag in MXML
3. BindingUtils.bindProperty/bindSetter methods in Action Script at runtime.
