E-Commerce Infrastructure
  • What worldwide structure is required to support
    e-Commerce?
  • Network
  • Machines
  • Protocols
  • Security
  • Payment

10
The Internet
  • The fundamental technology linking business and
    people around the world in less than 1 second
  • Nothing competes with it
  • How does it work?
  • How big is it?
  • Who owns it? Who governs it?
  • How does it grow? How big can it get?
  • What architecture allows this?
  • What are the limitations?

11
Internet Infrastructure
Mercy College Internet Server
It is a global collection of networks, both big
and small. These networks connect together in
many different ways to form the single entity
that we know as the Internet. In fact, the very
name comes from this idea of interconnected
networks.
12
Large ISP, UUNET
Most large communications companies have their
own dedicated backbones connecting between
various regions. In each region, the company
has a Point of Presence (POP). The POP is a
place for local users to access the company's
network, often through a local phone number or
dedicated line
13
What are Fiber Optics
  • Fiber optics (optical fibers) are long, thin
    strands of very pure glass about the diameter of
    a human hair. They are arranged in bundles called
    optical cables and used to transmit light signals
    over long distances.

It has following parts
  • core - thin glass center of the fiber where the
    light travels
  • cladding - outer optical material surrounding the
    core that reflects the light back into the core
  • buffer coating - plastic coating that protects
    the fiber from damage and moisture

14
Client/Server Architecture
  • Fundamental Internet structure
  • Client requests service server provides it
  • Data exchanged only through real-time messages
  • Server may become a client to a different server

15
Network Topologies
  • More than two computers causes complications
  • Each machine on a network must have a unique
    address
  • If machine 2 sends a message to machine 4, what
    tells 1, 3 and 5 to ignore it, but 4 to listen?
  • Ethernet protocol

Web Server Basics
19
Internet Server
  • The server is the heart of the technical
    architecture, receiving requests from Internet
    users, retrieving the information locally or from
    networked devices and replying.
  • Selection and sizing of this machine is critical
    task, typically presenting a tradeoff between
    performance and cost.

20
Web Server
Web server - A Web server is a piece of computer
software that can respond to a browser's request
for a page, and deliver the page to the Web
browser through the Internet. You can think of
a Web server as an apartment complex, with each
apartment housing someone's Web page. In order
to store your page in the complex, you need to
pay rent on the space. Pages that live in this
complex can be displayed to and viewed by anyone
all over the world. Your landlord is called
your host, and your rent is usually called your
hosting charge. Every day, there are millions
of Web servers delivering pages to the browsers
of tens of millions of people through the network
we call the Internet.

Protocol
Domain Name
Web Page
Verisign.com How can you get the URL that you
want?
23
Lets Display
  • http//www.site.com
  • /index.htm
  • /dir1/dir2/index.htm (Directory structure)
  • /cgi-win/maillist.exe (Evoking a mail list
    perform a function and than put the result on the
    web)

24
UNIX v.s. Windows
  • The two basic options are
  • UNIX based platforms(IBM, Sun, HP)
  • Microsoft NT based, Intel platforms
  • MS products generally cost less than UNIX
    platforms.
  • UNIX is a more mature OS than Windows based
    servers. As a result it delivers a better
    performance for the same hardware configuration.
  • UNIX administration, requires more complex
    skills.
  • If you dont have in-house UNIX expertise,
    investing in an UNIX based server may require a
    large maintenance cost.

25
Client / Server
  • In general, all of the machines on the Internet
    can be categorized
  • as two types
  • Server
  • Clients
  • Those machines that provide services (like Web
    servers or FTP servers) to other machines are
    servers.
  • And the machines that are used to connect to
    those services are clients.
  • When you connect to Yahoo at www.yahoo.com to
    read a page, Yahoo is providing a machine
    (probably a cluster of very large machines), for
    use on the Internet, to service your request.
    Yahoo is providing a server.
  • Your machine, on the other hand, is probably
    providing no services to anyone else on the
    Internet. Therefore it is a user machine, also
    known as a client.
  • It is possible and common for a machine to be
    both a server and a client, but for our purposes
    here you can think of most machines as one or the
    other

26
Domain Name Servers
  • If you spend any time on the Internet sending
    email or browsing the web, then you use Domain
    Name Servers without even realizing it.
  • Domain Name Servers, or DNS, are an incredibly
    important but completely hidden part of the
    Internet, and they are fascinating!
  • The DNS system forms one of the largest and most
    active distributed databases on the planet, and
    without DNS the Internet would shut down very
    quickly.

27
The Basic Idea
  • When you use the web or send an email message,
    you use a domain name to do it. For example, the
    following URL
  • http//www.mercy.edu
  • Contains the domain name mercy.edu. So does this
    email address
  • Bozdogan_at_mercy.edu
  • Human-readable names like mercy.edu are easy for
    human beings to remember, but they don't do
    machines any good. All of the machines use names
    called IP Addresses to refer to one another. For
    example, the machine that humans refer to as
    www.mercy
  • .edu has an IP address of 216.27.61.137. Every
    time you use a domain name, you use the
    Internet's domain name servers (DNS) to translate
    the human-readable domain name into the
    machine-readable IP address.
  • During a day of browsing and emailing, you might
    access the domain name servers hundreds of times!

28
The Internet
  • Protocols (TCP/IP, HTTP)
  • Addressing schemes
  • Domain names, Domain Name servers
  • URLs
  • Browsers
  • Programming
  • HTML,Perl, Common Gateway Interface (CGI)
  • Java,
  • Web architecture
  • What web systems look like

Firewall
  • The firewall is typically a hardware/software
    combination that controls the traffic between
    your internal network and the public internet.
  • Although a firewall can be directly incorporated
    into an Internet server, it is most commonly a
    specialized computer.
  • The configuration is a challenging task and
    should be performed by experts.

31
Firewall
As you can see all inbound and outbound Internet
traffic must pass through the firewall
32
Would you leave your companies front door
unlocked at night? 
  • Obviously not, so why leave doors to your network
    open? If your network is connected to the
    Internet a firewall is an absolute must. Some of
    the reasons companies do not currently have a
    firewall in place 
  • They feel the threat of an attack to their
    system(s) is low
  • They think that a firewall is difficult to set up
    and maintain
  • They think that the implementation of a firewall
    solution would be a significant investment
  • They are un-informed about the many ways their
    system(s) can be compromised and the amount of
    freely available tools the average person can use
    to do so

33
Would you leave your companies front door
unlocked at night? 
  • There are many firewall solutions available today
    ranging in price from under 1000 to tens of
    thousands of dollars. Typically a firewall is
    either a standalone device or a software package
    that usually requires a dedicated machine or
    server to run on.

Electronic Payments
Invoices
35
Data Interchange
  • How can sites exchange information without prior
    agreement?
  • What do the data fields mean? price, extended
    price, unit price, prix, ????, t?µ?, ?, XAC12
  • XML Extensible Markup Language

Data Exchange Problem
Different systems and applications use
different names and formats for the same
information
SOURCE FTISOFT
38
How to Make Data Portable
  • Tell what the data means
  • Tell how the data is structured
  • Tell how it should look
  • BUT DO THESE SEPARATELY. MIXING IS BAD
  • The meaning -- XML
  • The structure -- DTD (document type definition)
  • The formatting -- XSL (Extensible style sheet)
  • Example XML catalog structure

SO COMPUTERS CAN UNDERSTAND IT

    large datasets
  • discover trends, relationships, dependencies
  • make predictions
  • target customers
  • In eCommerce, data comes from
  • customers themselves
  • cookies
  • external databases
  • data matching
  • DoubleClick, etc.
  • Digital rights management tools (what we read and
    how much)
  • library records

49
Mass Personalization

50
Outline
  • What is personalization?
  • Personalization is based on data
  • How can data about people be acquired?
  • From people themselves
  • From their clickstream
  • From outside data sources
  • How can data be used
  • To improve the customers experience?
  • To help the company?

51
Mass Personalization
  • Treating each user as an individual
  • key is INFORMATION
  • How to acquire and store information about
    customers
  • Cookies
  • Question and response
  • Clickstream analysis
  • External databases.
  • How to use information effectively and instantly

52
What is Personalization?
  • Addressing customers by name and remembering
    their preferences
  • Showing customers specific content based on who
    they are and their past behavior
  • Empowering the customer. Examples Lands End,
    llbean
  • Product tailoring. Example dell.com
  • Connecting to a human being when necessary.
    CallMe
  • Adeptra TeleBanner
  • Allowing visitors to customize a site for their
    specific purposes
  • Users are 20-25 more likely to return to a site
    that they tailored (Jupiter Communications, Inc.)

53
Need For Personalization
  • In the real-world
  • Customer relationship is mediated by people
  • Personalization is critical PEOPLE are PEOPLE
  • On the Web
  • Too many customers too few employees
  • Orders are entered by machine follow-up is by
    machine
  • Customer relationship is mediated by machines
  • Personalization is critical
  • Uniqueness (everyone is different)
  • Efficiency (everyone has limited time)

54
Store Visitors in the Real World
  • Customer
  • buys something
  • pays cash
  • uses a credit card
  • uses a store charge card
