What Data Mining IS and IS NOT? Various Data Mining Techniques Steps in the Data Mining Process CRISP-DM Examples of Data Mining Applications Data Mining Issues Questions What is Data Mining?
The exploration and analysis of large quantities of data in order to discover meaningful patterns and rules (Berry and Linoff). A user-centric, interactive process which leverages analysis technologies and computing power. A group of techniques that find relationships that have not previously been discovered. A relatively easy task that requires knowledge of the business problem/subject matter expertise. "Computers and algorithms don't mine data; people do!"
