  • 1. E-Commerce and E-Business Introduction to Computer Science 2007-2008
  • 2. Aims • Describing the phases a company goes through using Internet for business • Describing the forms of e-commerce • Describing the purpose and uses of intranets and extranets • Describing the use od web sites to support commercial transactions • Describing the ethical issues of e-commerce 4626. Introd to Computer Science
  • 3. Contents 1. E-Commerce in perspective 2. Intranets: internal business processes 3. Extranets: business alliances 4. B2C: customer-centered web design 5. Technical requirements for e-commerce 6. Ethical issues of e-commerce 4626. Introd to Computer Science
  • 4. • Created in 1994 • Opened in July 1995 as a virtual book-stores Jeff Bezos. Amazon founder • 20 mill. customers in 160 countries • Survivor of .dot crises • Powerful recommendation system 4626. Introd to Computer Science
  • 5. E-commerce in Perspective Sharing business information, maintaining business relationships and conducting business transactions through the use od telecomm. networks Involves reorganising business processes 4626. Introd to Computer Science
  • 6. E-comm Transforms Business • .com companies (virtual) • Essential, or at least important for the rest • Increases speed and efficiency of business processes • Variants: e-commerce (electronic) i-commerce (internet) m-commerce (mobile) 4626. Introd to Computer Science
  • 7. E-Comm Models B C business-to-business business-to-consumer B (B2B) (B2C) consumer-to-business consumer-to-consumer C (C2B) (C2C) Put examples of each case 4626. Introd to Computer Science
  • 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 4626. Introd to Computer Science
  • 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 4626. Introd to Computer Science
  • 20. 4626. Introd to Computer Science
  • 21. Company Policies A Code of Ethics • Privacy policy of the organisation • Permission to transmit people data • How company inform customers about the use of personal data • Ownership about network posting and communications • Tracking of user behaviours 4626. Introd to Computer Science
