Data Mining
Data mining, an often overused and misunderstood term in data warehousing, is the
use of mathematical algorithms to model relationships in the data that wouldn??™t be
apparent by using other tools. Most companies shouldn??™t approach data mining
unless analysts have met the following criteria:
??? An understanding of the quality and meaning of the data in the warehouse.
??? Business insight gained using other tools and the warehouse.
??? An understanding of a business issue being driven by too many variables to
model outcomes in any other way.
In other words, data-mining tools are not a replacement for the analytical skills of
data warehouse users.
The data-mining tools themselves can rely on a number of techniques to produce the
relationships, such as:
??? Extended statistical algorithms, provided by statistical tools vendors, that can
highlight statistical variations in the data.
