Dimension
A characteristic of an OLAP measure. Purchase date, customer type, customer location, and sales region are examples of dimensions.
data warehouse
A facility for managing an organization's BI data.
Supervised data mining
A form of data mining in which data miners develop a model prior to the analysis and apply statistical techniques to determine the validity of that model and to estimate values of the parameters of the model.
unsupervised data mining
A form of data mining whereby the analysts do not create a model or hypothesis before running the analysis. Instead, they apply the data mining technique to the data and observe the results. With this method, analysts create hypotheses after the analysis to explain the patterns found.
Algorithm
A set of procedures used to solve a mathematical problem.
RFM Score
Abbreviation of Recency, Frequency, and Monetary Volume; a means to quantify the value of a customer relationship; useful as a basis for segmentation.

shows sample RFM results for Big 7 Sports (R=5, F=5, and M=3). Big 7 sports has ordered recently and orders frequently. But its M score of 3 indicates that it does not order the most expensive goods
From these scores, the sales team can conclude that Big 7 Sports is a good, regular customer and that it should attempt to up-sell more expensive goods to Big 7 Sports. No one on the sales team should even think about the third customer, Miami Municipal.
