Chapter Preview
  • This chapter surveys the most common business
    intelligence and knowledge-management
    applications, discusses the need and purpose for
    data warehouses, and explains how business
    intelligence applications are delivered to users
    as business intelligence systems.
  • Along the way, youll learn tools and techniques
    that MRV can use to identify the guides that
    contribute the most (and least) to its
    competitive strategy.
  • Well wrap up by discussing some of the potential
    benefits and risks of mining credit card data.

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

CRM 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.

7
Why 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

Business 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

11
Business 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

12
Tools 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.

14
Basic Reporting Operations
  • Reporting tools produce information from data
    using five basic operations
  • Sorting
  • Grouping
  • Calculating
  • Filtering
  • Formatting

15
List of Sales Data
16
Data 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.

Formatted for Easier Understanding
  • This figure shows even better information thats
    been filtered and formatted according to specific
    criteria.

19
What 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.

20
What 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.

Fig 9-6 Example of RFM Score Data
21
Interpreting 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)
22
RFM 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

23
Interpreting 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.

24
Interpreting 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

25
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.
  • Remarkable characteristic of OLAP reports is that
    they are dynamic. The viewer of the report can
    change reports format, hence the term online.

26
How 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

27
OLAP 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

  • 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
    California

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

Data 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.

How do BI Tools Obtain Data?
39
What 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

40
What 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

41
Decision 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

42
Create 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.

43
Decision 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

44
Summary 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

Decision 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

47
A 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

48
A 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.

Market-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
52
Market-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

53
Market-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

54
Market-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.

55
Regression 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

56
Neural 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

57
What are typical data-mining applications?
58
DATA MINING
  • Data-mining software includes many forms of AI
    such as neural networks and expert systems

59
Data 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

60
Other 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

61
Data 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.

What 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

64
Data 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.

65
What 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.

  • 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.

Problems 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.

Data 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

75
Data 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

KNOWLEDGE 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

78
Tacit 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.

The Four Modes of Knowledge Conversion
TO
Explicit Knowledge
Tacit Knowledge
Socialization (Sympathized Knowledge)
Externalization (Conceptual Knowledge)
Tacit Knowledge
Transferring tacit knowledge through shared
experiences, apprenticeships, mentoring
relationships, onthe-job training, Talking at
the water cooler
Articulating and thereby capturing tacit
knowledge through use of metaphors, analogies,
and models
FROM
Combination (Systematic Knowledge)

Primary 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.

83
Sharing 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.

84
Two 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.

85
Two 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.

86
Fig 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.

87
Fig 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.

88
Expert 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

89
Problems 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.

90
Expert 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.

91
Pharmacy 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
    issued if the system detects a problem with a
    patients prescriptions.

How 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
94
What 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.

95
What 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.

96
BI 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.

97
BI 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

98
BI 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.

99
Report 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.

100
What 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

2020?
  • 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.
