Data Mining: What Is It?  The process of extracting patterns from data.  Knowing what to ask.  Knowing how to ask.  Knowing how to present the data.

Educating Our Consumers  There is a tendency for insufficiently knowledgeable "consumers" of the results to attribute "magical abilities" to data mining, treating the technique as a sort of all-seeing crystal ball.

Sample Set vs. Entire Population  The discovery of a particular pattern in a particular set of data does not necessarily mean that pattern is representative of the whole population from which that data was drawn. Hence, an important part of the process is the verification and validation of patterns on other samples of data verification and validation
