Sun Tzu in The Art of War
• To succeed in war, one should have full

and
and
full knowledge of the enemy’s strengths and
weaknesses.
• Lack of either one might result in defeat.
Many businesses today say “how can I understand
my competitor when I can’t even understand myself.
That is what we are trying to solve using
business intelligence.
The Problem:
• With all of the data being captured and generated
by SCM, CRM and ERP systems, as well as the other
digital data being created and transmitted (spreadsheets,
fields in database files, word processing documents, video clips, email and text
messages, voice mail, etc.)

year
– Some believe it will soon double monthly
• Data is a

An Ideal Business Scenario
An account manager, on her way to a client visit, looks up past
proposals, as well as the client’s ordering, payment, delivery,
support and marketing history. At a glance, she can tell that
the client’s ordering volumes have dropped lately.
A few queries later, she understands that the client had support
issues with a given product. She calls her support
department and learns that the defective product will be
replaced within 24 hours.
In addition, the marketing records show that the client recently
attended a user conference and expressed interest in a new
product line.
With this information, she is prepared for a constructive sales
call. She understands all aspects of a client’s relationship with
her firm, understands the client’s issues and can confidently
address new sales opportunities.

ultimate destination of passengers who change airlines in
hub cities: is there a new route that should be added?

Goals of Data Mining
• C
• Trying to assign records to one of a predetermined set of classes.
• E
• Determine values for an unknown continuous variable or estimate
future values.
• Affinity grouping
• D
• Clustering
• Segment a diverse/differing population of records into groupings
with common characteristics
Most common forms of Data Mining
• Cluster analysis
• Association detection
• Statistical analysis
Cluster Analysis
•
Cluster analysis –
a technique used to
into mutually
exclusive
such
that the members of
each group are as close
together as possible to one another and the different
groups are as far apart as possible
•
CRM systems depend on cluster analysis to segment
customer information and identify behavioral traits
–
Segment by
, best customers or one-time customer.
Association Detection
•
Association detection – reveals the degree to
and the nature
and frequency of these relationships in the
information

Statistical Analysis
•
A wide range of statistical tools that can be used to build
various statistical models, examine the model’s
assumptions and validity, as well as compare and contrast
the various models to determine the best one to use for a
particular business issue

Various types of statistical analysis that might be performed

• By adding a Page Field to a Pivot Table, you can add
another dimension of information: 3-D (rows and
columns and layers).
– Creating a 3-dimensional Pivot Table in Excel is a means
of conceptually building a data warehouse. Page fields
represent the depth layer
