Business intelligence (BI) systems analyze operational data to provide information that can help with management and planning. BI involves extracting data from databases and analyzing it to make informed business decisions. Key components of BI systems include data acquisition, analysis, and publishing results. Common BI tools include reporting tools, data mining tools, and online analytical processing (OLAP). BI infrastructure leverages technologies like Hadoop, in-memory computing, and analytical platforms to handle large, diverse datasets. Common BI users are power users who create reports and casual users who consume them.

14. BUSINESS INTELLIGENCE AND ANALYTICS CAPABILITIES
– Production reports: These are predefined reports based on
industry specific requirements .
– Parameterized reports: Users enter several parameters as
in a pivot table to filter data and isolate impacts of
parameters. For instance,
• you might want to enter region and time of day to understand how
sales of a product vary by region and time.
8/19/2023 1-14

15. BUSINESS INTELLIGENCE AND ANALYTICS CAPABILITIES
• Dashboards/scorecards: These are visual tools for presenting
performance data defined by users.
• Ad hoc query/search/report creation: These allow users to create
their own reports based on queries and searches.
• Drill down: This is the ability to move from a high-level summary
to a more detailed view.
• Forecasts, scenarios, models: These include the ability to perform
linear forecasting, what-if scenario analysis, and analyze data using
standard statistical tools.

16. BI Capabilities Example
8/19/2023 16

17. BI Infrastructure
• an array of tools for obtaining useful information from all the
different types of data used by businesses today, including
semi-structured and unstructured big data in vast quantities.
• These capabilities include
– Data warehouse and data mart
– Hadoop,
– in-memory computing, and
– analytical platforms.
8/19/2023 17

18. 8/19/2023 18

19. Hadoop
• For handling unstructured and semi-structured data
in vast quantities, as well as structured data,
organizations are using Hadoop.
• Hadoop is an open source software framework
managed by the Apache Software Foundation that
enables
– distributed parallel processing of huge amounts of data
across inexpensive computers.
8/19/2023 19

20. Key services:
• Hadoop consists of several key services:
– the Hadoop Distributed File System (HDFS) for data
storage and
– MapReduce for high-performance parallel data
processing.
– HDFS links together the file systems on the numerous
nodes in a Hadoop cluster to turn them into one big file
system.
– Hadoop’s MapReduce was inspired by Google’s
MapReduce system for breaking down processing of huge
datasets and assigning work to the various nodes in a
cluster.
8/19/2023 20

21. • HBase, Hadoop’s non-relational database, provides rapid
access to the data stored on HDFS and a
transactional platform for running high-scale real-time
applications.
• Hadoop can process large quantities of any kind of data,
including structured transactional data, loosely structured
data such as Facebook and Twitter feeds, complex data such
as Web server log files, and unstructured audio and video
data.
• Hadoop runs on a cluster of inexpensive servers, and
processors can be added or removed as needed. Companies
use Hadoop for analyzing very large
21

22. In-Memory Computing
• Another way of facilitating big data analysis is to use in-
memory computing, which relies primarily on a computer’s
main memory (RAM) for data storage.
(Conventional DBMS use disk storage systems.)
• Users access data stored in system primary memory, thereby
eliminating bottlenecks from retrieving and reading data in a
traditional, disk-based database and dramatically shortening
query response times.
• In-memory processing makes it possible for very large sets of
data, amounting to the size of a data mart or small data
warehouse, to reside entirely in memory.
8/19/2023 22

23. • Leading commercial products for in-memory computing
include SAP’s High Performance Analytics Appliance (HANA)
and Oracle Exalytics.
• Each provides a set of integrated software components,
including in-memory database software and specialized
analytics software, that run on hardware optimized for in-
memory computing work.
8/19/2023 23

24. • Centrica, a gas and electric utility, uses HANA to quickly
capture and analyze the vast amounts of data generated by
smart meters.
• The company is able to analyze usage every 15 minutes, giving
it a much clearer picture of usage by
neighborhood, home size, type of business served, or building
type.
• HANA also helps Centrica show its customers their energy
usage patterns in real-time using online and mob
8/19/2023 24

25. Analytic platforms
• Commercial database vendors have developed specialized
high-speed analytic platforms using both relational and non-
relational technology that are optimized for analyzing large
datasets.
• These analytic platforms such as
– IBMNetezza and Oracle Exadata, feature preconfigured hardware-
software systems that are specifically designed for query processing
and analytics
8/19/2023 25

26. Analytic platforms contd…
• For example,IBM Netezza features tightly integrated
database, server, and storage components that
handle complex analytic queries 10 to 100 times
faster than traditional systems.
• Analytic platforms also include in-memory systems
and NoSQL non-relational database management
systems.
8/19/2023 26

27. BI Tools
1. Reporting Tools
• Integrate data from multiple systems
• Sorting, grouping, summing, averaging, comparing data
2. Data-mining Tools
• Used to discover hidden patterns and relationships
• Use sophisticated statistical techniques, regression analysis, and decision
tree analysis , Market-basket analysis
3. Knowledge-management tool
• Create value by collecting and sharing human knowledge about products,
product uses, best practices, other critical knowledge
8/19/2023 27

28. Reporting Tools
• Reporting tools produce information from data using
five basic operations:
• Sorting
• Grouping
• Calculating
• Filtering
• Formatting

29. RFM Analysis
RFM analysis allows you to analyze and rank customers according to
purchasing patterns as this figure shows.
..R = how recently a customer purchased your products
..F = how frequently a customer purchases your products
..M = how much money a customer typically spends on your products
8/19/2023 29

30. RFM Analysis ….
Divides customers into five groups and assigns a score from 1 to 5
• R score 1 = top 20 percent in most recent orders
• R score 5 = bottom 20 percent (longest since last order)
• F score 1 = top 20 percent in most frequent orders
• F score 5 = bottom 20 percent least frequent orders
• M score 1 = top 20 percent in most money spent
• M score 5 = bottom 20 percent in amount of money spent

31. Interpreting RFM Score result ….
8/19/2023 1-31

32. Online Analytical processing (OLAP)
• OLAP, a second type of reporting tool, is more generic than
RFM.
• OLAP provides the ability to sum, count, average, and perform
other simple arithmetic operations on groups of data.
• ability to manipulate, analyze large volumes of data from
multiple perspectives

• Data is analyzed to reveal hidden correlations, patterns, and
trends
• Uses variety of techniques to find hidden patterns and
relationship in large pool of data and infer rules from them
that can be used to predict future behavior and guide
decision.
8/19/2023 1-38

39. Data Mining Tools
i. Query-and-reporting tools – similar to QBE tools, SQL, and
report generators
ii. Intelligent agents – utilize AI tools to help you “discover”
information and trends
iii. Multidimensional analysis (MDA tools) – slice-and-dice
techniques for viewing multidimensional information
iv. Statistical tools – for applying mathematical models to data
warehouse information
8/19/2023 1-39

40. Data Mining Tools/Techniques
• Can be of Two Types
–Supervised data mining :Regression and NN
–Un supervised data mining: Decision tree and cluster
analysis
8/19/2023 1-40

41. Supervised data mining …
Model developed before analysis (ie regression ,NN)
• Statistical techniques used to estimate parameters
•Examples:
..Regression analysis—measures impact of set of variables
on one another
..Used for making predictions
8/19/2023 1-41

42. Supervised data mining… Neural Network
• Popular supervised data-mining technique used to
predict values and make classifications such as “good
prospect” or “poor prospect” customers
8/19/2023 42

43. Unsupervised data mining….
• Analysts do not create model before running analysis. i.e.
cluster analysis, decision tree etc.
• Analysts create hypotheses after analysis to explain patterns
found.
• No prior model about the patterns and relationships that
might exist . Common statistical technique used:
• Cluster analysis to find groups of similar customers from
customer order and demographic data
8/19/2023 1-43

44. Unsupervised data mining…Decision tree
• Hierarchical arrangement of criteria that predict a
classification or value
• Basic idea of a decision tree
..Select attributes most useful for classifying something
on some criteria that create disparate groups
• More different or pure the groups, the better the
classification
8/19/2023 44

45. Decision tree
8/19/2023 1-45

46. Create Set of If/Then Decision Rules
If student is a junior and works in a restaurant, then
predict grade > 3.0.
• If student is a senior and is a non-business major,
then predict grade < 3.0.
• If student is a junior and does not work in a
restaurant, then predict grade < 3.0.
• If student is a senior and is a business major, then
make no prediction.
8/19/2023 1-46

47. Market Basket Analysis (MBA)
Market-basket analysis is a data-mining technique for
determining sales patterns.
– Uses statistical methods to identify sales patterns in large volumes of
data
– Shows which products customers tend to buy together
– Used to estimate probability of customer purchase
– Helps identify cross-selling opportunities
• "Customers who bought book X also bought book Y”

48. Hypothetical sales data of 1000 items at a Dive shop
8/19/2023 1-48

49. 8/19/2023 49
Support
..Probability that two items will be bought together
..Fins and masks purchased together 150 times,
thus support for fins and a mask is 150/1,000, or
15 percent
..Support for fins and weights is 60/1,000, or 6
percent
..Support for fins along with a second pair of fins is
10/1,000, or 1 percent
Market-Basket terminologies

50. Market-Basket terminologies
Confidence
..What proportion of the customers who bought a mask also
bought fins?
..Conditional probability estimate
• Example:
» Probability of buying fins = 28%
» Probability of buying swim mask = 27%
• After buying fins,
» Probability of buying mask = 150/270 or 55.56%
• ..Likelihood that a customer will also buy fins almost doubles, from
28% to 55.56%.
• Thus, all sales personnel should try to sell fins to anyone buying a
mask.
8/19/2023 1-50

51. Market-Basket terminologies…
Lift
..Ratio of confidence to base probability of buying
item
..Shows how much base probability increases or
decreases when other products are purchased
•Example:
..Lift of fins and a mask is confidence of fins given
a mask, divided by the base probability of fins.
..Lift of fins and a mask is .5556/.28 = 1.98
