  3. Learning ObjectivesTo understand the elements of technological system that relate to e-commerceTo describe the architecture of network and Internet that facilitate e-commerceTo explain the concept of EDI and how it worksTo explore the kinds of e-commerce softwareTo identify security technology in e-commerce

  4. Introduction E-Commerce today Definition of e-commerce in three ways So, instead of using mail, telephone or fax to send catalogues, order forms, notes confirm of receipt, e- commerce uses electronic means of communication.

  5. The purpose:Providing a comprehensive descriptions and ideas of basic technology for electronic commerce. We begin by technological system for e-commerce, and then to Internet and network, electronic data interchange, electronic commerce hardware and software and finally, to security technology in electronic commerce.

  6. I. Technological System for E-Commerce1.1 Structure of E-CommerceApplicationInfrastructure services Messages Multimedia NetworkOther two aspects(Figure 1)

  7. 1.2 E-Technology Architecture E-application rules E-application distribution/ integration E-data E-networks (Figure 2)

  8. 1.3 Technologies Associated with E-CommerceA web browser  Internet videoconferencing . E-mail Internet phoneA discussion list or newsgroup A web page and a website

  9. II. Internet and NetworkInternet Network Computer networks and the Internet, which connect computer networks around the world to each other, from the basic technology structure that underlies all electronic commerce.

  10. 2.1 Internet Protocols ARPANET and Network Control Protocol (NCP). --Should not require any internal change --Retransmitted from their source network.--Do not retain information --No global control

  11. 2.2 TCP/IPTransmission Control Protocol (TCP) and Internet Protocol (IP). The TCP control the disassembly of a message or a file into packets before it is transmitted over the Internet. The IP specifies the addressing details for each packet, labeling each with the packet’s origination and destination address.

  12. 2.3 World Wide WebThe part of the Internet known as the World Wide Web, or more simply, the Web, is a subset of the computers on the Internet that are connected to each other in a specific way that makes them and their contents easily accessible to each other.

  13. 2.4 Intranets and ExtranetsIntranets are an excellent way to distribute internal corporate information. Extranets are networks that connect companies with suppliers, business partners, or other authorized users. Figure 3. Intranet and Logistics management

  14. 2.5 Internet Connection OptionsInternet access providers (IAP or ISPs)--Telephone--Broadband--Leased line--Wireless --Bluetooth--Wireless Ethernet (Wi-Fi)

  15. 2.6 Seven Layers1. Physical layer2. Data link layer3. Network layer4. Transport layer5. Session layer6. Presentation layer7. Application layer

  16. 2.7 LAN, WAN and NetworkA network of computers that are located closed together in the same building-is called a local area network, or LAN. Networks of computer that are connected over greater distance are called wide area networks, or WANs.Figure 4. LAN, WAN and Internet

  17. 2.8 Public and Private NetworksA public network is any computer network or telecommunications network that is available to the public.  A private network is a private, leased-line connection between two companies that physically connects their intranets to one another.

  18. 2.9 Virtual Private Networks (VPN)A virtual private network (VPN) is an extranet that uses public networks and their protocols to send sensitive data to partners, customers, suppliers and employees using a system called IP tunneling or encapsulation.

  19. III. Electronic Data InterchangeElectronic data interchange (EDI) is the collection of standards for exchanging data between computers in separate organization.3.1 Broader EDI StandardsCommonly used ASCX12 transaction sets Commonly used UN/EDIFACT transaction sets

  20. 3.2 How EDI WorksB2B, B2C   Figure 5. EDI and Purchase process3.3 Value-Added-NetworksDirect connection or indirect connection.Definition of VANAdvantages and Disadvantages of VANFigure 6. Indirect connection EDI Through a VAN

  21. 3.4 EDI on the InternetReasons on the InternetOpen Architecture of the Internet and benefits.

  22. IV. E - Commerce Hardware and Software4.1 Web Server HardwareCompanies use a wide variety of computer brands, types and sizes to host electronic commerce operations. 4.1.1 Server ComputersWeb server computers generally have more memory, larger (and faster) hard disk drives, and faster processors than the typical desktop or notebook PCs.

  23. 4.1.2 Web Hosting ChoicesSelf-hosting Shared hosting Dedicated hosting

  24. 4.2 Software for Web ServersSome Web server software can run on only one computer operating system, while some can run on several operating systems.   4.2.1 Operating Systems for Web servers4.2.2 Web server Software

  25. 4.3 Functions of Electronic Commerce Software4.3.1 Basic functionsCatalog Display  Shopping Cart  Transaction Processing4.3.2 Advanced FunctionsReasons Advanced Functions cover the middleware, application integration and Databases and integration with ERP Systems.

  26. V. Security Technology in Electronic Commerce5.1 Internet Security Classifications and PolicyClassifications: SecurityIntegrityNecessary A security policy requirements: Six points 

  27. 5. 2 Encryption and DecryptionEncryption is the coding of information by using a mathematically based program and a secret key to produce a string of characters that is unintelligible. Figure 7. Encryption, Decryption and Purchase Process

  28. 5.3 Digital CertificatesA digital certificate is an attachment to an e-mail message or a program embedded in a Web page that verifies that the sender or We site is who or what it claims to be.  A digital certificate includes six main elements.

  29. 5.4 FirewallsFirewalls are computer and software combination that is installed at the Internet entry point of networked system. Functions Firewall computers have three characteristics:Figure 8. Firewall and Internet

  30. Conclusion Electronic commerce technologies and strategies are key factors for today’s e-commerce, as the Internet continues to become more popular, electronic commerce techniques will evolve to meet the challenges. References The End
