Module 3 SLP will introduce the basic concepts of computer network.docx

Module 3 SLP will introduce the basic concepts of computer
networks. The IT infrastructure uses a mixture of computer
hardware from different vendors. Large and complex databases
that need central storage are found on mainframes or specialized
servers, whereas smaller databases and parts of large databases
are loaded on PCs and small servers. Client-server computing is
often used to distribute more processing power to the
desktop. The course materials take a look at the different types
of networks that exist, with the primary focus on the LAN. The
readings in computer networks continue with an introduction to
the concept of layers, which is central to understanding how
computer networks operate.
SLP Assignment Expectations
After reading the articles, please answer the following questions
and prepare a PPT presentation with 10-12 slides, excluding
cover slide and reference list slide.
What is the significance of telecommunications for
organizations and society? What is a telecommunications
system? What are the principle functions of all
telecommunications systems? Briefly describe the company
where these systems will be in place and then explain your
reasoning for its details.
Assignment Expectations
Your presentation will be evaluated on the following criteria:
Answers to the questions and the accompanying explanation
must be given in 10-12 slides excluding cover and reference
slides.
· Precision: You see what the module is all about and structure
your paper accordingly. You draw on a range of sources and
establish your understanding of the historical context of the
question. You carry out the exercise as assigned or carefully
explain the limitations that prevented your completing some
parts. (Running out of time isn’t generally considered an
adequate limitation).

· Clarity: Your answers are clear and show your good
understanding of the topic. You see what the module is all about
and structure your paper accordingly.
· Critical thinking: The paper incorporates your reactions,
examples, and applications of the material to business and
illustrates your reflective judgment and good understanding of
the concepts. It is important to read the "Required Reading" in
the Background material plus other sources you find relevant.
· Breadth and Depth: You provide informed commentary and
analysis—simply repeating what your sources say does not
constitute an adequate paper. The scope covered in your paper
is directly related to the questions of the assignment and the
learning outcomes of the module.

11-*
IntroductionData leverage and data-driven decision making is
important for obtaining competitive advantageIt can be a tough

slog getting an organization to the point where it has a data
asset that it can leverageIn many organizations data lies
dormant, spread across inconsistent formats and incompatible
systems, unable to be turned into anything of valueMany firms
have been shocked at the amount of work and complexity
required to pull together an infrastructure that empowers its
managers
11-*
Data, Information, and KnowledgeData: Raw facts and
figuresInformation: Data presented in a context so that it can
answer a question or support decision makingKnowledge:
Insight derived from experience and expertise

Understanding How is Data Organized: Key Terms and
TechnologiesDatabase: A single table or a collection of related
tablesDatabase management systems (DBMS): Sometimes called
“database software”; software for creating, maintaining, and
manipulating dataStructured query language (SQL): A language
used to create and manipulate databasesDatabase administrator
(DBA): Job title focused on directing, performing, or
overseeing activities associated with a database or set of
databasesIncludes database design, creation, implementation,
maintenance, backup and recovery, policy setting and
enforcement, and security
11-*
TechnologiesKey concepts that all managers should know:A

table or file refers to a list of dataA database is either a single
table or a collection of related tablesA column or field defines
the data that a table can holdA row or record represents a single
instance of whatever the table keeps track ofA key is the field
used to relate tables in a database
11-*
TechnologiesTable or file: A list of data, arranged in columns
(fields) and rows (records)Column or field: A column in a
database table. Columns represent each category of data
contained in a record (e.g., first name, last name, ID number,
data of birth)
11-*
TechnologiesRow or record: A row in a database table. Records
represent a single instance of whatever the table keeps track of
(e.g., student, faculty, course title)Key: A field or combination
of fields used to uniquely identify a record, and to relate
separate tables in a database. Examples include social security
number, customer account number, or student IDRelational
database: The most common standard for expressing databases,
whereby tables (files) are related based on common keys
11-*
Where Does Data Come From?For organizations that sell
directly to their customers, transaction processing systems
represent a fountain of potentially insightful dataTransaction
processing systems (TPS): A system that records a transaction

(some form of business-related exchange), such as a cash
register sale, ATM withdrawal, or product returnTransaction:
Some kind of business exchangeThe cash register is the primary
source that feeds data to the TPSTPS can generate a lot of bits,
it’s sometimes tough to match this data with a specific customer
11-*
Where Does Data Come From?Enterprise software (CRM, SCM,
and ERP)Firms set up systems to gather additional data beyond
conventional purchase transactions or Web site monitoring
CRM or customer relationship management systems are used to
empower employees to track and record data at nearly every
point of customer contactSupply chain management (SCM) and
enterprise resource planning (ERP) systems touch every aspect
of the value chain
11-*
Where Does Data Come From?SurveysFirms supplement
operational data with additional input from surveys and focus
groupsDirect surveys can tell you what your cash register
can’tMany CRM products have survey capabilities that allow
for additional data gathering at all points of customer contact
11-*
Where Does Data Come From?External sourcesIf your firm has
partners that sell products for you, then you’ll likely rely
heavily on data collected by othersData bought from sources
available to all might not yield competitive advantage on its
own, but it can provide key operational insight for increased

efficiency and cost savings
11-*
Data Rich, Information PoorMany organizations are data rich
but information poorFactors holding back information
advantageLegacy system: Older information systems that are
often incompatible with other systems, technologies, and ways
of conducting businessMost transactional databases aren’t set
up to be simultaneously accessed for reporting and analysis

Data Asset in Action: Harrah’s Solid Gold CRM for the Service
SectorHarrah’s Entertainment provides an example of
exceptional data asset leverage in the service sector, focusing
on how this technology enables world-class service through
customer relationship managementHarrah’s has leveraged its
data-powered prowess to move from an also-ran chain of
casinos to become the largest gaming company by revenue
11-*
Collecting DataHarrah’s collects customer data on everything
you might do at their propertiesThe data is then used to track
your preferences and to size up whether you’re the kind of
customer that’s worth pursuing
11-*

Collecting DataThe ace in Harrah’s data collection hole is its
Total Rewards loyalty card systemThe system is constantly
being enhanced by an IT staff of seven hundred, with an annual
budget in excess of one hundred million dollarsIt is an opt-in
loyalty program, but customers consider the incentives to be so
good that the card is used by some 80 percent of Harrah’s
patrons
11-*
Who are the Most Valuable Customers?With detailed historical
data at hand Harrah’s can make fairly accurate projections of
customer lifetime value (CLV)Customer lifetime value (CLV):
The present value of the likely future income stream generated
by an individual purchaserThe firm tracks over ninety
demographic segments, and each responds differently to
different marketing approaches
11-*
Who are the Most Valuable Customers?Identifying segments
and figuring out how to deal with each involves:An iterative
model of mining the data to identify patternsCreating a
hypothesis, then testing that hypothesis against a control
groupTurning to analytics to statistically verify the
outcomeFrom its data, Harrah’s realized that most of its profits
came from:LocalsCustomers forty-five years and older
11-*
Data Driven Service: Get Close (But Not Too Close) to Your
CustomersHarrah’s identifies the high value customers and
provides special attention to themCustomers could obtain

reserved tables and special offersIt monitors even gamblers
suffering unusual losses, and provide feel-good offers to
themThe firm’s CRM effort monitors any customer behavior
changesCustomers come back to Harrah’s because they feel that
those casinos treat them better than the competition
11-*
Data Driven Service: Get Close (But Not Too Close) to Your
CustomersHarrah’s focus on service quality and customer
satisfaction are embedded into its information systems and
operational proceduresEmployees are measured on metrics that
include speed and friendliness and are compensated based on
guest satisfaction ratingsThe process effectively changed the
corporate culture at Harrah’s from an every-property-for-itself
mentality to a collaborative, customer-focused
enterpriseHarrah’s is keenly sensitive to respecting consumer
dataSome of its efforts to track customers have misfired
11-*
InnovationHarrah’s is constantly tinkering with new innovations
that help it gather more data and help push service quality and
marketing program successInteractive bill boards, RFID-enabled
poker chips and under-table RFID readers, incorporation of
drink ordering to gaming machines, and touch-screen and
sensor-equipped tabletop are examples of such innovations
11-*
StrategyThe data is the major competitive advantage for
Harrah’sThe data advantage creates intelligence for a high-
quality and highly personal customer experienceThe data gives

the firm a service differentiation edgeThe loyalty program
represents a switching costThe firm’s technology has been
pretty tough for others to match and the firm holds many patents
11-*
ChallengesGaming is a discretionary spending item, and when
the economy tanks, gambling is one of the first things
consumers will cutHarrah’s holds twenty-four billion dollars in
debt from expansion projects and the buyoutThe firm is now in
a position many consider risky due to debt assumed as part of
an overly optimistic buyout

The Data Asset: Databases,
Business Intelligence, and
Competitive Advantage
1. INTRODUCTION
L E A R N I N G O B J E C T I V E S
1. Understand how increasingly standardized data, access to
third-party data sets, cheap, fast
computing and easier-to-use software are collectively enabling a
new age of decision making.
2. Be familiar with some of the enterprises that have benefited
from data-driven, fact-based de-
cision making.
The planet is awash in data. Cash registers ring up transactions
worldwide. Web browsers leave a trail
of cookie crumbs nearly everywhere they go. And with radio
frequency identification (RFID), invent-
ory can literally announce its presence so that firms can
precisely journal every hop their products
make along the value chain: “I’m arriving in the warehouse,”
“I’m on the store shelf,” “I’m leaving out
the front door.”
A study by Gartner Research claims that the amount of data on
corporate hard drives doubles
every six months,[1] while IDC states that the collective
number of those bits already exceeds the num-
ber of stars in the universe.[2] Wal-Mart alone boasts a data
volume well over 125 times as large as the
entire print collection of the U.S. Library of Congress, and
rising.[3] You’ll hear managers today broadly
refer to this torrent of bits as “Big Data.”

And with this flood of data comes a tidal wave of opportunity.
Increasingly standardized corporate
data, and access to rich, third-party data sets—all leveraged by
cheap, fast computing and easier-to-use
software—are collectively enabling a new age of data-driven,
fact-based decision making. You’re less
likely to hear old-school terms like “decision support systems”
used to describe what’s going on here.
The phrase of the day is business intelligence (BI), a catchall
term combining aspects of reporting,
data exploration and ad hoc queries, and sophisticated data
modeling and analysis. Alongside business
intelligence in the new managerial lexicon is the phrase
analytics, a term describing the extensive use
of data, statistical and quantitative analysis, explanatory and
predictive models, and fact-based manage-
ment to drive decisions and actions.[4]
The benefits of all this data and number crunching are very real,
indeed. Data leverage lies at the
center of competitive advantage we’ve studied in the Zara,
Netflix, and Google cases. Data mastery has
helped vault Wal-Mart to the top of the Fortune 500 list. It
helped Harrah’s Casino Hotels grow to be
twice as profitable as similarly sized Caesars and rich enough to
acquire this rival (Harrah’s did decide
that it liked the Caesars name better and is now known as
Caesars Entertainment). And data helped
Capital One find valuable customers that competitors were
ignoring, delivering ten-year financial per-
formance a full ten times greater than the S&P 500. Data-driven
