In the last lessons, you got an overview of the features available from Flex Data Services (FDS) and learned how FDS can be used with your Flex applications to provide greater functionality. In this lesson, you will explore how a Flex application can register itself as a listener for new data pushed from the server, which makes it possible to have the server asynchronously send updates to the clients. You will use this to automatically update the Dashboard charts to reflect new sales in real time!
When a user completes an order, the Application server sends a gateway message to the FDS server, which sends an update to the Dashboard application in real time. The charts are updated to always display current information.
