(e.g., finding not only total sales but also
sales by region, by product, or by
salesperson). Finding the detailed
sources
An Overview

 Online analytical processing (OLAP)
An information system that enables the
user, while at a PC, to query the system,
conduct an analysis, and so on. The
result is generated in seconds
Online Analytical Processing (OLAP)

 OLAP versus OLTP
 OLTP concentrates on processing repetitive
transactions in large quantities and
conducting simple manipulations
 OLAP involves examining many data items
complex relationships
 OLAP may analyze relationships and look
for patterns, trends, and exceptions
 OLAP is a direct decision support method

 Types of OLAP
 Multidimensional OLAP (MOLAP)
OLAP implemented via a specialized
multidimensional database (or data store)
that summarizes transactions into
multidimensional views ahead of time

 Types of OLAP
 Relational OLAP (ROLAP)
The implementation of an OLAP database
on top of an existing relational database
 Database OLAP and Web OLAP (DOLAP
and WOLAP)
 Desktop OLAP

1. Multidimensional
conceptual view for
formulating queries
2. Transparency to the user
3. Easy accessibility: batch
and online access
4. Consistent reporting
performance
5. Client/server architecture:
the use of distributed
resources
6. Generic dimensionality
7. Dynamic sparse matrix
handling
8. Multiuser support rather
than support for only a
single user
9. Unrestricted cross-
dimensional operations
10. Intuitive data manipulation
11. Flexible reporting
12. Unlimited dimensions and
aggregation level
Codd’s 12 Rules for OLAP

 Four types of processing that are
performed by analysts in an organization:
1. Categorical analysis
2. Exegetical analysis
3. Contemplative analysis
4. Formulaic analysis

Reports and Queries
 Reports
 Routine reports
 Ad hoc (or on-demand) reports
 Multilingual support
 Scorecards and dashboards
 Report delivery and alerting
• Report distribution through any touchpoint
• Self-subscription as well as administrator-based
distribution
• Delivery on-demand, on-schedule, or on-event
• Automatic content personalization

Reports and Queries
 Ad hoc query
A query that cannot be determined prior to
the moment the query is issued
 Structured Query Language (SQL)
A data definition and management
language for relational databases. SQL
front ends most relational DBMS

Multidimensionality
 Multidimensionality
The ability to organize, present, and
analyze data by several dimensions, such
as sales by region, by product, by
salesperson, and by time (four dimensions)
 Multidimensional presentation
 Dimensions
 Measures
 Time

Multidimensionality
 Multidimensional database
A database in which the data are
organized specifically to support easy and
quick multidimensional analysis
 Data cube
A two-dimensional, three-dimensional, or
higher-dimensional object in which each
dimension of the data represents a
measure of interest

Multidimensionality
 Cube
A subset of highly interrelated data that is
organized to allow users to combine any
attributes in a cube (e.g., stores, products,
customers, suppliers) with any metrics in
the cube (e.g., sales, profit, units, age) to
create various two-dimensional views, or
slices, that can be displayed on a
computer screen

Multidimensionality
 Multidimensional tools and vendors
 Tools with multidimensional capabilities often
work in conjunction with database query
systems and other OLAP tools

Multidimensionality
 Limitations of dimensionality
 The multidimensional database can take up
significantly more computer storage room than a
summarized relational database
 Multidimensional products cost significantly more than
standard relational products
 Database loading consumes significant system
resources and time, depending on data volume and
the number of dimensions
 Interfaces and maintenance are more complex in
multidimensional databases than in relational
databases

Advanced Business Analytics
 Data mining and predictive analysis
 Data mining
 Predictive analysis
Use of tools that help determine the probable
future outcome for an event or the likelihood of
a situation occurring. These tools also identify
relationships and patterns

Data Visualization
 Data visualization
A graphical, animation, or video
presentation of data and the results of data
analysis
 The ability to quickly identify important trends
in corporate and market data can provide
competitive advantage
 Check their magnitude of trends by using
predictive models that provide significant
business advantages in applications that drive
content, transactions, or processes

Data Visualization
 New directions in data visualization
 In the 1990s data visualization has moved
into:
 Mainstream computing, where it is integrated
with decision support tools and applications
 Intelligent visualization, which includes data
(information) interpretation

Data Visualization
 New directions in data visualization
 Dashboards and scorecards
 Visual analysis
 Financial data visualization

Geographic
Information Systems (GIS)
 Geographical information system (GIS)
An information system that uses spatial
data, such as digitized maps. A GIS is a
combination of text, graphics, icons, and
symbols on maps

Geographic
 As GIS tools become increasingly
sophisticated and affordable, they help
more companies and governments
understand:
 Precisely where their trucks, workers, and
resources are located
 Where they need to go to service a customer
 The best way to get from here to there

Geographic
 GIS and decision making
 GIS applications are used to improve decision making
in the public and private sectors including:
• Dispatch of emergency vehicles
• Transit management
• Facility site selection
• Drought risk management
• Wildlife management
 Local governments use GIS applications for used
mapping and other decision-making applications

Geographic
 GIS combined with GPS
 Global positioning systems (GPS)
Wireless devices that use satellites to enable
users to detect the position on earth of items
(e.g., cars or people) the devices are attached
to, with reasonable precision

Geographic
 GIS and the Internet/intranets
 Most major GIS software vendors provide
Web access that hooks directly to their
software
 GIS can help the manager of a retail
operation determine where to locate retail
outlets
 Some firms are deploying GIS on the Internet
for internal use or for use by their customers
(locate the closest store location)

Real-Time BI, Automated Decision Support,
and Competitive Intelligence
 Real-time BI
 The trend toward BI software producing real-
time data updates for real-time analysis and
real-time decision making is growing rapidly
 Part of this push involves getting the right
information to operational and tactical
personnel so that they can use new BA tools
and up-to-the-minute results to make
decisions

Real-Time BI, Automated Decision
Support, and Competitive Intelligence
 Real-time BI
 Concerns about real-time systems
• An important issue in real-time computing is that
not all data should be updated continuously
• when reports are generated in real-time because
one person’s results may not match another
person’s causing confusion
• Real-time data are necessary in many cases for
the creation of ADS systems

 Real-time BI
 Automated decision support (ADS) or
enterprise decision management (EDM)
A rule-based system that provides a solution
to a repetitive managerial problem. Also
known as enterprise decision management
(EDM)

 Real-time BI
 Business rules
Automating the decision-making process is
usually achieved by encapsulating business
user expertise in a set of business rules that
are embedded in a rule-driven workflow (or
other action-oriented) engine

 Real-time BI
 Characteristics and benefits of ADS
ADS are most suitable for decisions that must
be made frequently and/or rapidly, using
information that is available electronically

 Capabilities of ADSs
 Rapidly builds rules-based applications and deploys
them into almost any operating environment
 Injects predictive analytics into rule-based applications
 Provides services to legacy systems
 Combines business rules, predictive models, and
optimization strategies flexibly into state-of-the-art
decision-management applications
 Accelerates the uptake of learning from decision criteria
into strategy design, execution, and refinement

 ADS applications
 Product or service configuration
 Yield (price) optimization
 Routing or segmentation decisions
 Corporate and regulatory compliance
 Fraud detection
 Dynamic forecasting
 Operational control

 Implementing ADS—software companies
provide these components to ADS:
 Rule engines
 Mathematical and statistical algorithms
 Industry-specific packages
 Enterprise systems
 Workflow applications

 Competitive intelligence
 Many companies continuously monitor the
activities of their competitors to acquire
competitive intelligence
 Such information gathering drives business
performance by increasing market knowledge,
improving knowledge management, and
raising the quality of strategic planning

BA and the Web: Web
Intelligence and Web Analytics
 Using the Web in BA
 Web analytics
The application of business analytics
activities to Web-based processes,
including e-commerce

BA and the Web: Web
 Clickstream analysis
The analysis of data that occur in the Web
environment.
 Clickstream data
Data that provide a trail of the user’s
activities and show the user’s browsing
patterns (e.g., which sites are visited,
which pages, how long)

BA and the Web: Web

Usage, Benefits,
and Success of BA
 Usage of BA
 Almost all managers and executives can use
some BA systems, but some find the tools too
complicated to use or they are not trained
properly.
 Most businesses want a greater percentage of
the enterprise to leverage analytics; most of
the challenges related to technology adoption
involve culture, people, and processes

Usage, Benefits,
and Success of BA
 Success and usability of BA
 Performance management systems (PMS) are
BI tools that provide scorecards and other
relevant information that decision makers use
to determine their level of success in reaching
their goals

Usage, Benefits,
and Success of BA
 Why BI/BA projects fail
1. Failure to recognize BI projects as cross-
organizational business initiatives and to
understand that, as such, they differ from
typical standalone solutions
2. Unengaged or weak business sponsors
3. Unavailable or unwilling business
representatives from the functional areas

Usage, Benefits,
and Success of BA
4. Lack of skilled (or available) staff, or
suboptimal staff utilization
5. No software release concept (i.e., no
iterative development method)
6. No work breakdown structure (i.e., no
methodology)

Usage, Benefits,
and Success of BA
7. No business analysis or standardization
activities
8. No appreciation of the negative impact
of “dirty data” on business profitability
9. No understanding of the necessity for
and the use of metadata
10. Too much reliance on disparate methods
and tools

Usage, Benefits,
and Success of BA
 System development and the need for
integration
 Developing an effective BI decision support
application can be fairly complex
 Integration, whether of applications, data
sources, or even development environment, is
a major CSF for BI
