Oracle Business Activity Monitoring (BAM) 11g R1 architecture leverages the push-based mechanism to deliver the high volume of data changes to the frontend web browser in real time, which is the key differentiator from other conventional reporting solutions that use the pulling approach for report rendering.

To help you understand the push-based mechanism and BAM Architecture, this chapter first introduces BAM key concepts, which are the prerequisites to learning BAM. We will then discuss an overview of the architecture, and its key server side components. Finally, you will see an explanation of the message flows in typical report opening and data change scenarios, so that you can understand what happens behind the scenes.
