Business Analytics, BI,Big Data, Data
Mining - What’s the difference?
• Business Analytics – Tools to explore past data
to gain insight into future business decisions.
• BI – Tools and techniques to turn data into
meaningful information.
• Big Data –data sets that are so large or
complex that traditional data processing
applications are inadequate.
• Data Mining - Tools for discovering
patterns in large data sets.
4.
Businesses Need Supportfor
Decision Making
• Uncertain economics
• Rapidly changing environments
• Global competition
• Demanding customers
• Taking advantage of information acquired by
companies is a Critical Success Factor.
The Information Gap
•The shortfall between gathering information
and using it for decision making.
– Firms have inadequate data warehouses.
– Business Analysts spend 2 days a week gathering
and formatting data, instead of performing
analysis. (Data Warehousing Institute).
– Business Intelligence (BI) seeks to bridge the
information gap.
7.
Data Mining
• “Datamining is an interdisciplinary subfield of
computer science. It is the computational process of
discovering patterns in large data sets involving
methods at the intersection of artificial intelligence,
machine learning, statistics, and database systems.” -
Wikipedia
• Examining large databases to produce new
information.
– Uses statistical methods and artificial intelligence to
analyze data.
– Finds hidden features of the data that were not yet known.
8.
BI
• Tools andtechniques to turn data into
meaningful information.
– Process: Methods used by the organization to turn
data into knowledge.
– Product: Information that allows businesses to
make decisions.
9.
BI Applications
• CustomerAnalytics
• Human Capital Productivity Analysis
• Business Productivity Analytics
• Sales Channel Analytics
• Supply Chain Analytics
• Behavior Analytics
10.
What is BusinessIntelligence?
• Collecting and refining information from many
sources (internal and external)
• Analyzing and presenting the information in
useful ways (dashboards, visualizations)
• So that people can make better decisions
• That help build and retain competitive
advantage.
BI Initiatives
• 70%of senior executives report that analytics will
be important for competitive advantage. Only 2%
feel that they’ve achieved competitive advantage.
(zassociates report)
• 70-80% of BI projects fail because of poor
communication and not understanding what to
ask. (Goodwin, 2010)
• 60-70% of BI projects fail because of technology,
culture and lack of infrastructure (Lapu, 2007)
Data Warehouse
• Collectionof data
from multiple
sources (internal
and external)
• Summary, historical and raw data from
operations.
• Data “cleaning” before use.
• Stored independently from
operational data.
• Broken down into DataMarts for
use.

5 Tasks ofData Mining in Business
• Classification – Categorizing data into
actionable groups. (ex. loan applicants)
• Estimation – Response rates, probabilities of
responses.
• Prediction – Predicting customer behavior.
• Affinity Grouping – What items or services are
customers likely to purchase together?
• Description – Finding interesting patterns.
18.
Data Mining Techniques
•Market Basket Analysis
• Cluster Analysis
• Decision Trees and Rule Induction
• Neural Networks
19.
Market Basket Analysis
•Finding patterns or sequences in the way that
people purchase products and services.
• Walmart Analytics
– Obvious: People who buy Gin also buy tonic.
– Non-obvious: Men who bought diapers would also
purchase beer.
20.
Cluster Analysis
• Groupingdata into like clusters based on
specific attributes.
• Examples
– Crime map clusters to better deploy police.
– Where to build a cellular tower.
– Outbreaks of Zika virus.
21.
Summary
• Explained BI,Analytics, Data Marts and Big
Data.
• Defined the characteristics of data for good
decision making.
• Described data mining in detail.
• Explained and gave examples of
market basket and cluster analysis.
