Chances are very strong that your enterprise
might go down, with the steady and rapid inflow of business data, when you do not
have a piece of software at the doorway collecting business events and aggregate
them to raise necessary notifications and triggers.
Most of the enterprise grade applications need to work with a continuous stream
of data by actively monitoring the stream and filtering them based on defined
business rules. They seldom work with a finite data store or database. This is because
corrective actions can be performed more elegantly at the stream level than at the
data store level. Hence, in the business process, the current state of data is of very less
importance compared to the asynchronous and continuous data that flow through.
A business event processing tool allows business users and system integrators to
put together the middleware solution, thus triggering more focused actions and
enhancing automation and efficiency. There are quite a few tools in the market
that do business event processing effectively. In this chapter, we will be discussing
the Intelligent Event Processor (IEP) Service Engine. The IEP supports editing,
deploying, and executing event processors that can work on multiple continuous
data streams.
In this chapter, we will discuss the following topics:

opportunities evident through monitoring and responding to critical business events.
