This event fires periodically as data arrives from data source objects that asynchronously transmit their data.
In a data-driven system, occasionally you will need to wait for the arrival of some data. This event triggers when the data has arrived, and you can build a script that works with the data that is triggered from this event, rather than build some polling code that sits there busily waiting for things to arrive.
