If the application performance limits the business processes it is supposed to be supporting, the application must be tuned.
Today’s businesses depend heavily on their databases. Should applications and data become unavailable, the entire business may halt. Revenue and customers may be lost and penalties may be incurred. Bad press can have a lasting effect on both customers and stock prices. Certainly, providing continuous data availability is essential for today’s businesses.
The key to making programs fast is to make them do practically nothing!
Chapter 1: Databases with cool sounding names
The great liability of the engineer compared to men of other professions is that his works are out in the open where all can see them. His acts, step by step, are in hard substance. He cannot bury his mistakes in the grave like the doctors. He cannot argue them into thin air or blame the judge like the lawyers. He cannot, like the architects, cover his failures with trees and vines. He cannot, like the politicians, screen his shortcomings by blaming his opponents and hope that the people will forget. The engineer simply cannot deny that he did it. If his works do not work, he is damned. That is the phantasmagoria that haunts his nights and dogs his days. He comes from the job at the end of the day resolved to calculate it again. He wakes in the night in a cold sweat and puts something on paper that looks silly in the morning. All day he shivers at the thought of the bugs which will inevitably appear to jolt its smooth consummation.
On the other hand, unlike the doctor his is not a life among the weak. Unlike the soldier, destruction is not his purpose. Unlike the lawyer, quarrels are not his daily bread. To the engineer falls the job of clothing the bare bones of science with life, comfort, and hope. No doubt as years go by people forget which engineer did it, even if they ever knew. Or some politician puts his name on it. Or they credit it to some promoter who used other people’s money with which to finance it. But the engineer himself looks back at the unending stream of goodness which flows from his successes with satisfactions that few professions may know. And the verdict of his fellow professionals is all the accolades he wants.
Jessica Flack: I believe that science sits at the intersection of these three things — the data, the discussions and the math. It is that triangulation — that’s what science is. And true understanding, if there is such a thing, comes only when we can do the translation between these three ways of representing the world.
It’s hard to believe that Microsoft is 41 years old. In that time, its had its ups (think Windows XP with around one billion sales) and its downs (think Windows ME, which lasted for less than 18 months). But one thing that’s clear is Microsoft has cleverly re-invented itself, re-booted and disrupted its own business in a massive way. Some would argue Microsoft is now “cool” again.
