6. E-comm Transforms
Business
• .com companies (virtual)
• Essential, or at least important for the rest
• Increases speed and efficiency of business
processes

8. Intranets
• Basis for B2E: internet
supporting internal activties
• Improve comm. inside the
company
• Advantages
• cross-platform
• open standards
• minimal user training
4626. Introd to Computer Science

9. Characteristics of a B2E
Intranet
• physical tech: LAN with Ethernet
• middleware: software which handles
physical comm. (TCP/IP based)
• firewall sw for security
• standard web applications:
browsers, e-mail clients, file sharing
4626. Introd to Computer Science

10. How To Use B2E
Intranets
• Information access for employees:
centralised databases with a common interface
• Collaboration and teamwork:
distribute information, remote working groups
• Internal business transactions:
increase efficiency and reduces paperwork

11. Extranets
Business Alliances
• Link intranets of different companies
(e-marketplaces)
• Activities between trusted business partners
Functionalities
• place orders
• check stock level
• confirm inoice status
• exchange business information
4626. Introd to Computer Science

12. Extranets
with Public Networks
• use public, open comm. lines without additional
security mechanisms
• low cost, but low security (and high risk)
• protection: firewalls and logons
4626. Introd to Computer Science

13. Extranets with VPN
• use public, open comm. lines
• an special protocol creates a virtual tunnel
across the intranets
• VPNs are becoming the preferred method:
economical and secure enough
4626. Introd to Computer Science

14. Extranets
with Private Networks
• physically attached lines (leased)
• high cost
• high security levels
• extent of access for external
users (only business partners)
4626. Introd to Computer Science

15. B2C
• Customer centered web design
• Often interactive features included
• CRM: customer relationship management
• critical without personal contact
• database with relevant information:
preferences, past purchases, communications...
4626. Introd to Computer Science

16. Features of Well
Designed Sites
• Speed of transactions
• Large, up-to-date selection (the ‘Long Tail’)
• Ease of use
• Secure transations
• After-sale features
4626. Introd to Computer Science

17. Technical Requirements:
Web Server
• Hw&Sw to store pages and
handle trafic
• Only large companies have
the know-how and the
capability to run their own
server
4626. Introd to Computer Science

18. Technical Requirements:
Hosting Service
• Provide space in their own servers and tools
to set up business web pages
• Handle almost all
transactions steps
(including payments)
4626. Introd to Computer Science

19. Technical Requirements:
Software
• Provides commercial services
• Database (catalogue)
+ front-end
• Capabilities: security, search
engine, data analysis
