any business questions can be easily answered by directly querying a database; for
example, “What is the most popular page on our website?” or “Who are our top
customers?” Other questions require deeper exploration — for example, the most
popular paths through the website or common characteristics of top customers. Data mining
provides the tools to analyze the answers to these questions.

Data mining is the algorithmic discovery of patterns from large quantities of data. You can create a
variety of data mining algorithms within the Analysis Services environment.

Analysis Services implements algorithms to extract information addressing several categories of
questions:

■ Segmentation: Groups items with similar characteristics. For example, develop profi les of
top customers.
■ Classification: Places items into categories. For example, determine which e-mails are
likely to be spam.
■ Association: Sometimes called market basket analysis, this determines which items tend to
occur together. For example, “Customers who bought this book also bought....”
■ Estimation: Estimates a value. For example, estimate revenue from a customer.
