There are many circumstances in the world that surround and influence purchasers. To make the required measurements, the world is “frozen” in its state for the particular purchaser and the surrounding circumstances captured. Several variables are measured. Each measurement is, of course, subject to the point distortion, or error, described previously. 3 represents such a single measurement. The central point of each circle represents the idealized point value, and the surrounding circle represents the unavoidable accompanying fuzz or error.
The world exists in a way that humans generally agree on. It consists of objects that we can identify, such as cars, trees, cost-of-living adjustments, cartons of milk, beams of light, gross national products, beauty, truth, and justice. For data exploration through data mining it is these objects that form the basic material of the world to be explored.

Data mining explores the relationships that exist between these objects.
No one who expected to achieve anything useful would approach a lump of unknown substance, put on a blindfold, and whack at it with whatever tool happened to be at hand. Why this is thought possible with data mining tools is difficult to say! Unfortunately, focusing on the data mining modeling tools as the primary approach to a problem often leads to the problem being formulated in inappropriate ways. Significantly, there may be times when data mining tools are not the right ones for the job. It is worth commenting on the types of questions that are particularly well addressed with a data-mined model.
