- Business intelligence information that people
use to support/improve their decision-making
efforts - Principle BI enablers include
- Technology
- People
- Culture

6CRM and BI Example
- A Grocery store in U.K.
- Every Thursday afternoon
- Young Fathers (why?) shopping at store
- Two of the followings are always included in
their shopping list - Diapers and
- Beers
- What other decisions should be made as a store
manager (in terms of store layout)? - Short term vs. Long term
- IT (e.g., BI) helps to find valuable information
then decision makers make a timely/right decision
for improving/creating competitive advantages.
7Why Do Organizations Need Business Intelligence?
- Information systems generate enormous amounts of
operational data that contain patterns,
relationships, clusters, and other information
that can facilitate management, especially
planning and forecasting. Business intelligence
systems produce such information from operational
data. - Data communications and data storage are
essentially free, enormous amounts of data are
created and stored every day. - 12,000 gigabytes per person of data, worldwide in
2009

10Business Intelligence (BI) Tools
- BI systems provide valuable information for
decision making. (BI video) - Three primary BI systems
- Reporting Tools
- Integrate data from multiple systems
- Sorting, grouping, summing, averaging, comparing
data - RFM is one of the tool for reporting.
- Data-mining Tools
- Use sophisticated statistical techniques,
regression analysis, and decision tree analysis - Used to discover hidden patterns and
relationships - Market-basket analysis
11Business Intelligence Tools
- Knowledge-management tool
- Create value by collecting and sharing human
knowledge about products, product uses, best
practices, other critical knowledge - Used by employees, managers, customers,
suppliers, others who need access to company
knowledge
12Tools vs. Applications vs. Systems
- BI tool (e.g., decision-tree analysis) is one or
more computer programs. BI tools implement the
logic of a particular procedure or process. - BI application is the use of a tool on a
particular type of data for a particular purpose.
- BI system is an information system having all
five components (what are they?) that delivers
results of a BI application to users who need
those results.

14Basic Reporting Operations
- Reporting tools produce information from data
using five basic operations - Sorting
- Grouping
- Calculating
- Filtering
- Formatting
15List of Sales Data
16Data Sorted by Customer Name
- Reporting applications input data from a
source(s) and apply a reporting tool to the data
to produce information. The reporting system
delivers the information to users. - Basic reporting operations include sorting,
grouping, calculating, filtering, and formatting.
- This figure shows raw data before any reporting
operations are used.
Fig 9-2 Raw Sales Data
17- The figure on the left shows the raw sales data
sorted by customer names. - The figure on the right shows data thats been
sorted and grouped.

18Sales Data Filtered to ShowRepeat Customers and
Formatted for Easier Understanding
- This figure shows even better information thats
been filtered and formatted according to specific
criteria.

Customers
19What are typical reporting applications?
- RFM Analysis allows you to analyze and rank
customers according to purchasing patterns as
this figure shows. - Recency How recently a customer purchased items?
gt leads and opportunities - Frequency How frequently a customer purchased
items? gt retention - Monetary Value How much a customer spends on
each purchase? gt profitability - RFM Analysis
- Sort the data by date (for recency), times (for
frequency), and purchase amount (for money),
respectively - Divide the sorted data into five groups
- Assign 1 to top 20, 2 to next 20, 3 to the
third 20, 4 to the fourth 20 and 5 to the
bottom 20. - The the score, the better the
customer.
lower
20What does RFM analysis Tell?
- 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 - The the score, the better the
customer, and, consequently, the more profit the
company will be.
lower
Fig 9-6 Example of RFM Score Data
21Interpreting RFM Score Results
- Ajax has ordered recently and orders frequently.
M score of 3 indicates it does not order most
expensive goods. - A good and regular customer but need to attempt
to up-sell more expensive goods to Ajax - Bloominghams has not ordered in some time, but
when it did, ordered frequently, and orders were
of highest monetary value. - May have taken its business to another vendor.
Sales team should contact this customer
immediately. - Caruthers has not ordered for some time did not
order frequently did not spend much. - Sales team should not waste any time on this
customer. - Davidson in middle
- Set up on automated contact system or use the
Davidson account as a training exercise
80/20 Rule (Pareto Principle)
22RFM Tools Classify Customers?
- 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
23Interpreting RFM Score Results
- Ajax has ordered recently and orders frequently.
M score of 3 indicates it does not order most
expensive goods. - A good and regular customer but need to attempt
to up-sell more expensive goods to Ajax - Bloominghams has not ordered in some time, but
when it did, ordered frequently, and orders were
of highest monetary value. - May have taken its business to another vendor.
Sales team should contact this customer
immediately.
24Interpreting RFM Score Results
- Caruthers has not ordered for some time did not
order frequently did not spend much. - Sales team should not waste any time on this
customer. - Davidson in middle
- Set up on automated contact system or use the
Davidson account as a training exercise
25Online 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. - Remarkable characteristic of OLAP reports is that
they are dynamic. The viewer of the report can
change reports format, hence the term online.
26How Are OLAP Reports Dynamic?
- OLAP reports
- Simple arithmetic operations on data
- Sum, average, count, and so on
- Dynamic
- User can change report structure
- View online
- Measure
- Data item to be manipulatedtotal sales, average
cost - Dimension
- Characteristic of measurepurchase date, customer
type, location, sales region
27OLAP Summary
- Online Analytical Processing (OLAP) is more
generic than RFM and provides you with the
dynamic ability to sum, count, average, and
perform other arithmetic operations on groups of
data. Reports, also called OLAP cubes, use - Measures which are data items of interest. In the
figure below a measure is Store Sales Net . - Dimensions which are characteristics of a
measure. In the figure below a dimension is
Product Family.
Fig 9-7 OLAP Product Family by Store Type
28OLAP Reports
- OLAP cube
- Presentation of measure with associated
dimensions - a.k.a. OLAP report
- Users can alter format.
- Users can drill down into data.
- Divide data into more detail
- May require substantial computing power
29- This figure shows how you can alter the format of
a report to provide users with the information
they need to do their jobs.
- Fig 9-8 OLAP Product Family Store Location by
Store Type
30- This figure shows how you can divide data into
more detail by drilling down through the data.
- Fig 9-9 OLAP Product Family Store Location by
Store Type, Drilled Down to Show Stores in

31- OLAP servers are special products that 1) read
data from an operational database, 2) perform
some preliminary calculations, and then3) store
the results in an OLAP database

32On-Line Analytic Processing (OLAP)
- Enables mangers and analysts to interactively
examine and manipulate large amounts of detailed
and consolidated data from different dimensions. - Analytical Processing
- Drill-up (Consolidation) ability to move from
detailed data to aggregated data - Profit by Product gtgtgt Product Line gtgtgt Division
- Drill-down ability to move from summary/general
to lower/specific levels of detail - Revenue by Year gtgtgt Quarter gtgtgtgtWeek gtgtgtDay
- Slice and Dice ability to look across
dimensions - Sales by Region Sales

35Data Base, Data Warehouse and Data Marts
- Data base An organized collection of logically
related (current) data files. - Data Warehouse A data warehouse stores data from
current and previous years (historical data) that
have been extracted from the various operational
and management database of an organization. - Data mart a subset of data warehouse that holds
specific subsets of data for one particular
functional area or project.

38How do BI Tools Obtain Data?
39What are typical data-mining applications?
- Businesses use statistical techniques to find
patterns and relationships among data and use it
for classification and prediction. Data mining
techniques are a blend of statistics and
mathematics, and artificial intelligence (AI) and
machine-learning.
- Fig 9-11 Convergence Disciplines for Data Mining
40What are typical data-mining applications?
- Data mining is an automated process of discovery
and extraction of hidden and/or unexpected
patterns of collected data in order to create
models for decision making that predict future
behavior based on analyses of past activity. - There are two types of data-mining techniques
- Unsupervised data-mining characteristics
- No model or hypothesis exists before running the
analysis - Analysts apply data-mining techniques and then
observe the results - Analysts create a hypotheses after analysis is
completed - Cluster analysis, a common technique in this
category groups entities together that have
similar characteristics - Supervised data-mining characteristics
- Analysts develop a model prior to their analysis
- Apply statistical techniques to estimate
parameters of a model - Regression analysis is a technique in this
category that measures the impact of a set of
variables on another variable - Neural networks predict values and make
classifications. - Used for making predictions
41Decision Tree Analysis of MIS Class Grades
- Students characteristics
- Class (junior or senior), major, employment, age,
club affiliations, and other characteristics - Values used to create groups that were as
different as possible on the classification GPA
above or below 3.0 - Results
- Best criterionClass
- Next subdivide Seniors and Juniors into more pure
groups - Seniorsbusiness and non-business majors
- Juniorsrestaurant employees and non-restaurant
employees - Best classifier is whether the junior worked in a
restaurant
42Create Set of If/Then Decision Rules
- If student is a junior and works in a restaurant,
then predict grade gt 3.0. - If student is a senior and is a non-business
major, then predict grade lt 3.0. - If student is a junior and does not work in a
restaurant, then predict grade lt 3.0. - If student is a senior and is a business major,
then make no prediction.
43Decision Trees
- Decision tree
- Hierarchical arrangement of criteria that predict
a classification or value - Unsupervised data-mining technique
- 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
44Summary of Decision Tree Analysis
- A decision tree is a hierarchical arrangement of
criteria that predicts a classification or value.
Its an unsupervised data-mining technique that
selects the most useful attributes for
classifying entities on some criterion. It uses
ifthen rules in the decision process. Here are
two examples.
If student is a junior and works in a restaurant,
then predict grade 3.0
gt
If student is a senior and is a nonbusiness
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 prediction
no

46Decision Tree for Loan Evaluation
- Common business application
- Classify loan applications by likelihood of
default - Rules identify loans for bank approval
- Identify market segment
- Structure marketing campaign
- Predict problems
47A Decision Tree for a Loan Evaluation
- Classifying likelihood of default
- Examined 3,485 loans
- 28 percent of those defaulted
- Evaluation criteria
- Percentage of loan past due less than 50 percent
.94, no default - Percentage of loan past due greater than 50
percent .89, default - Subdivide groups A and B each into three
classifications CreditScore, MonthsPastDue, and
CurrentLTV
48A Decision Tree for a Loan Evaluation
- Resulting rules
- If the loan is more than half paid, then accept
the loan. - If the loan is less than half paid and
- If CreditScore is greater than 572.6 and
- If CurrentLTV is less than .94, then accept the
loan. - Otherwise, reject the loan.
- Use this analysis to structure a marketing
campaign to appeal to a particular market segment
- Decision trees are easy to understand and easy to
implement using decision rules. - Some organizations use decision trees to select
variables to be used by other types of
data-mining tools.

50Market-Basket Analysis
- Market-basket analysis is a supervised
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
51- Market-Basket Analysis is a supervised
data-mining tool for determining sales patterns.
It helps businesses create cross-selling
opportunities (i.e., buying relevant products
together). Two terms used with this type of
analysis are - Support the probability that two items will be
purchased together (e.g., Fins and Mask will be
purchased together) - Confidence a conditional probability estimate
(e.g., proportion of the customers who bought a
mask also bought fins) - Lift ratio of confidence to the base probability
(e.g., ratio between customers of buying fins
after buying mask and those buying fins of
walking into the store)
A Fins B Mask
P(Fins)280/1000.28
Lift is almost double
Fig 9-12 Market-Basket Example
52Market-Basket Terminology
- 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
53Market-Basket Terminology
- 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
54Market-Basket Terminology
- 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.
55Regression Analysis
- CellphoneWeekendMinutes 12 (17.5
CustomerAge) - (23.7 NumberMonthsOfAccount)
- Using this equation, analysts can predict number
of minutes of weekend cell phone use by summing
12, plus 17.5 times the customers age, plus 23.7
times the number of months of the account. - Considerable skill is required to interpret the
quality of such a model
56Neural Networks
- Neural networks
- Popular supervised data-mining technique used to
predict values and make classifications such as
good prospect or poor prospect customers - Complicated set of nonlinear equations
- See kdnuggets.com to learn more
57What are typical data-mining applications?
58DATA MINING
- Data-mining software includes many forms of AI
such as neural networks and expert systems
59Data Mining Analysis
- Data mining the process of analyzing data to
extract information not offered by the raw data
alone - To perform data mining users need data-mining
tools - Data-mining tool uses a variety of techniques
to find patterns and relationships in large
volumes of information and infers rules that
predict future behavior and guide decision making - An example
- Grocery Store in UK
60Other Data Mining Examples
- A telephone company used a data mining tool to
analyze their customers data warehouse. The
data mining tool found about 10,000 supposedly
residential customers that were expending over
1,000 monthly in phone bills. - After further study, the phone company discovered
that they were really small business owners
trying to avoid paying business rates
61Data Mining Examples (cont.)
- 65 of customers who did not use the credit card
in the last six months are 88 likely to cancel
their accounts. - If age lt 30 and income lt 25,000 and credit
rating lt 3 and credit amount gt 25,000 then the
minimum loan term is 10 years. - 82 of customers who bought a new TV 27" or
larger are 90 likely to buy an entertainment
center within the next 4 weeks.

63What Is the Purpose of Data Warehouses and Data
Marts?
- Purpose (video)
- To extract and clean data from various
operational systems and other sources - To store and catalog data for BI processing
- Extract, clean, prepare data
- Stored in data-warehouse DBMS
64Data Base, Data Warehouse and Data Marts
- Data base An organized collection of logically
related (current) data files. - Data Warehouse A data warehouse stores data from
current and previous years (historical data) that
have been extracted from the various operational
and management database of an organization. - Data mart a subset of data warehouse that holds
specific subsets of data for one particular
functional area or project.
65What is the purpose of data warehouses and data
marts?
- Data warehouses and data marts address the
problems companies have with missing data values
and inconsistent data. They also help standardize
data formats between operational data and data
purchased from third-party vendors. - These facilities prepare, store, and manage data
specifically for data mining and analyses.

67Data Warehouse Data Sources
- Internal operations systems
- External data purchased from outside sources
- Data from social networking, user-generated
content applications - Metadata concerning data stored in data-warehouse
meta database - Clickstream data of customers clicking behavior
on a Web site
68Data Base, Data Warehouse and Data Marts
- Data base An organized collection of logically

have been extracted from the various operational
and management database of an organization. - Data mart a subset of data warehouse that holds
specific subsets of data for one particular
functional area or project.
69- Figure 9-16, left, lists some of the data thats
readily available for purchase from data vendors - Some of the problems companies experience with
operational data are shown in figure 9-17 below.
- Granularity refers to whether data are too fine
or too coarse. - Clickstream data refers to the clicking behavior
of customers on Web sites. - The phenomenon called the curse of
dimensionalityjust because you have more
attributes doesnt mean you have a more
worthwhile predictor.
70Fig 9-16 Example Typical of Customer Credit Data
71Problems with Operational Data
- Dirty datamistakes in spelling or punctuation,
incorrect data associated with a field,
incomplete or outdated data or even data that is
duplicated in the database.
Fig 9-17 Problems of using Transaction Data for
Analysis and Data mining
72Examples of Dirty Data
- A value of B for customer gender
- 213 for customer age
- Value of 9999999999 for a U.S. phone number
- Part color of gren
- mail address of WhyMe_at_GuessWhoIAm.org.
73Problems with Operational Data
- Too much data causes
- Curse of dimensionality
- Problem caused by the exponential increase in
volume associated with adding extra dimensions to
a (mathematical) space. - Too many rows or data points
- With more attributes, the easier it is to build a
model that fits the sample data but that is
worthless as a predictor. - Major activities in data mining concerns
efficient and effective ways of selecting
attributes.
74Data Warehouses and Data Marts?
- Heres the difference between a data warehouse
and a data mart - A data warehouse stores operational data and
purchased data. It cleans and processes data as
necessary. It serves the entire organization. - A data mart is smaller than a data warehouse and
addresses a particular component or functional
area of an organization.
- Fig 9-18 Data Mart Examples
75Data Warehouses vs. Data Marts
- Data mart is a collection of data (video)
- Created to address particular needs
- Business function
- Problem
- Opportunity
- Smaller than data warehouse
- Users may not have data management expertise
- Need knowledgeable analysts for specific function
- Data extracted from data warehouse for a
functional area

77KNOWLEDGE MANAGEMENT
- The process of creating value from intellectual
capital and sharing that knowledge with
employees, managers, suppliers, customers, and
others who need it. - Reporting and data mining are used to create new
information from data, knowledge-management
systems concern the sharing of knowledge that is
known to exist.
- Knowledge management (KM) the process of
capturing, classifying, evaluating, retrieving,
and sharing information assets in a way that
provides context for effective decisions and
actions. - Knowledge management system (KMS) an
information system that supports the capturing
and use of an organizations know-how
78Tacit vs. Explicit Knowledge
- Intellectual and knowledge-based assets fall into
two categories - _______ knowledge is personal, context-specific
and hard to formalize and communicate - ________ knowledge can be easily collected,
organized and transferred through digital means.

Knowledge-Creating Company, 1995
82Primary Benefits of KM
- 1. KM fosters innovation by encouraging the free
flow of ideas. - 2. KM improves customer service by streamlining
response time. - 3. KM boosts revenues by getting products and
services to market faster. - 4. KM enhances employee retention rates by
recognizing the value of employees knowledge and
rewarding them for it. - 5. KM streamlines operations and reduces costs by
eliminating redundant or unnecessary processes. - KM preserves organizational memory by capturing
and storing the lessons learned and best
practices of key employees.
83Sharing of Document Content and Employee Knowledge
- Sharing Document Content
- Collaboration systems are concerned with document
creation and change management, KM applications
are concerned with maximizing content use.
84Two Typical Knowledge-Management Applications
- Two key technologies for sharing content in KM
systems - Indexingmost important content function in KM
applications that provide easily accessible and
robust means of determining if content exists and
a link to obtain the content. Used in conjunction
with search functions.
85Two Typical Knowledge-Management Applications
- RSS 2. (Real Simple Syndication)a standard for
subscribing to content sources on Web sites. An
RSS Reader program helps users to - Subscribe to content sources.
- Periodically check sources for new or updated
content through RSS feeds. - Place content summaries in an RSS inbox with link
to the full content. - Think of RSS as an email system for content
- Data source must provide what is termed an RSS
feed, which simply means that the site posts
changes according to one of the RSS standards.
86Fig 9-19 Interface of a Typical RSS Reader
- This figure shows a typical RSS reader. The left
pane shows RSS sources. Entries are grouped into
categories predetermined by the user.
87Fig 20 Blog Posts of SharePoint Team Member
- Blogs provide an easy way to share knowledge as
seen in this figure. You can use RSS feeds to
subscribe to thousands of blogs.
88Expert Systems
- Another form of knowledge management are expert
systems with the following characteristics - Expert systems attempt to capture human expertise
and put it into a format that can be used by
nonexperts. - Expert systems are rule-based systems that use
If?Then rules similar to those created by
decision-tree analysis, except they are created
from human experts instead of data-mining
systems. - Expert systems gather data from people rather
than using data-mining techniques
89Problems of Expert Systems
- Difficult and expensive to develop. They require
many labor hours from both experts in the domain
under study and designers of expert systems. High
opportunity cost of tying up domain experts. - Difficult to maintain. Nature of rule-based
systems creates unexpected consequences when
adding a new rule in middle of hundreds of
others. A small change can cause very different
outcomes. - No expert system has the same diagnostic ability
as knowledgeable, skilled, and experienced
doctors. Rules/actions change frequently.
90Expert Systems for Pharmacies
- Used as a safety net to screen decisions of
doctors and other medical professionals. These
systems help to achieve hospitals goal of
state-of-the-art, error-free care. - DoseChecker, verifies appropriate dosages on
prescriptions issued in the hospital. - PharmADE, ensures that patients are not
prescribed drugs that have harmful interactions. - Pharmacy order-entry system invokes these
applications as a prescription is entered. If
either system detects a problem with the
prescription, it generates an alert.
91Pharmacy Alert
- This is an example of the output from a medical
expert system that is part of a decision support
system. Based on the systems rules, an alert is

93How Are Business Intelligence Applications
Delivered?
- This figure shows the components of a generic BI
system. A BI application server delivers results
in a variety of formats to devices for
consumption by BI users. A BI server provides two
functions management and delivery.

Intelligence System
94What Are the Management Functions of a BI Server?
- The management function of a BI server maintains
metadata about the authorized allocation of BI
results to users. It tracks what results are
available, who is authorized to view them, and
when the results are provided to users. Here are
options for managing BI results - Users can pull their results from a Web site
using a portal server with a customizable user
interface. - A server can automatically push information to
users through alerts which are messages
announcing events as they occur. - A report server, a special server dedicated to
reports, can supply users with information.
95What Are the Management Functions of a BI Server?
- Maintains metadata about authorized allocation of
BI results to users - Tracks what results are available, what users are
authorized to view those results, and schedule to
provide results to authorized users. Adjusts
allocations as available results change and users
come and go.
96BI Servers Vary in Complexity and Functionality
- Some BI servers are simply Web sites from which
users can download, or pull BI application
results. - For example, a BI Web server might post results
of an RFM analysis for salespeople to query to
obtain RFM scores for their customers. Management
function for such a site would simply be to track
authorized users and restrict access.
97BI Servers Vary in Complexity and Functionality
and could operate as a portal server.
- This figure shows a portal that provides common
data to users. It can be used to help companies
manage their knowledge.
- Fig 9-23 Sample Portal, Provided by iGoogle
98BI Portals
- Portals might provide common data such as local
weather, and links to company news, and to BI
application results such as reports on daily
sales, operations, new employees, and results of
data-mining applications. - Authorized users are allowed to place reports,
data-mining results, or other BI application
results on their customized pages. - BI application server pushes the subscribed
results to the user.
99Report Server
- A special case of a BI application server that
serves only reports - BI application servers track results, users,
authorizations, page customizations,
subscriptions, alerts, and data for any other
functionality provided.
100What Are the Delivery Functions of a BI Server?
- Track authorized users
- Track the schedule for providing results to users
- Issue exception alerts that notify users of an
exceptional event - Procedures used depends on the nature of the BI
system - Procedures tend to be more flexible than those in
an operational system because users of a BI
system tend to be engaged in work that is neither
structured nor routine - Procedures are determined by unique requirements
of users - BI results can be delivered to any device, such
as computers, PDAs, phones, other applications
such as Microsoft Office, and as a SOA service

1042020?
- Through data mining, companies, known as data
aggregators, will know more about your
purchasing psyche than you, your mother, or your
analyst. - If you use your card to purchase secondhand
clothing, retread tires, bail bond services,
massages, casino gambling or betting you alert
the credit card company of potential financial
problems and, as a result, it may cancel your
card or reduce your credit limit. - Absent laws to the contrary, by 2020 your credit
card data will be fully integrated with personal
and family data maintained by the data
aggregators (like Acxiom and ChoicePoint). - By 2020, some online retailers will know a lot
more about you, data aggregators, and most
consumers purchases than well know ourselves.
