● Flex includes a large library of components (both UI and non-UI) that can be readily used.
● In many cases, the visual and/or behaviour of these components are not sufficient.
● Customised component can be built by extending an existing Flex component.

● Value objects (VO) are simply a class (or template) with predetermined properties.
● Main reason is to ease passing around an object within the application.
● Works very well when used in conjunction with customised component.
● VERY USEFUL concept especially for building mid to large scale application.
