At this point, if you are struggling with accepting that we can adequately model something so complex so simply, just remember how much we can learn about cars, rockets, and railroads by studying their models. We can glean some other interesting bits of knowledge from these models. Notice that in a CPU subsystem, a single large transaction will not block other transactions from receiving CPU service. Yet a single large IO transaction can block an entire device, forcing all the other transactions needing to be serviced by that same IO device to wait!

Computer hardware components (such as CPU and memory) are frequently upgraded and therefore change. Change also makes a perfect (even a near perfect) workload measurement impossible. To represent these complexities, we must abstract. Oracle transaction resource requirements fluctuate wildly. You must be very careful in determining, for example, the average CPU time it takes to service a transaction. For example, querying a customer may consume between 500 to 5,000 milliseconds of CPU time. This average is, you guessed it, a method of abstraction.

In fact, SLM should drive and provide focus for our forecasting-related projects. If you are a hard-core technology person, this can be difficult. I suspect that most of you reading this book have this kind of background, so throughout this book, I have taken extra care in helping you demonstrate the value of what you are doing and how that can support SLM-related initiatives. If our forecasting work does not support the management of service levels, then eventually its shrouded value will be unveiled to show a pure technical exercise, and our efforts will be put to an uncomfortable halt.
