Resource & Implementation

1. e-Commerce Building Blocks

   • Services
   • Distribution
     • E-mail Web Shared databases Online Catalogs Network Communities Shipping Infrastructure
   • Network
     • Internet VAN Cable TV Telephone Networks
   • Production
     • Databases Multimedia Authoring Information Production Manufacturing

2. e-Commerce Architecture

   • A key driver of success in the area of technology is to build an architecture that is robust and comprehensive enables organizations to develop and implement new e-commerce applications rapidly
   • Software Architecture
     • The definition of software architecture: architecture as the fundamental organization of a system embodied in its components, their relationships to each other and to the environment and the principles guiding its design and evolution
   • Client/Server Environment
     • C/S architecture is scalable horizontally (more clients can added) Vertically (more servers can be added)
     • Benefits of Good Architecture
       • E-commerce leaders who have such an infrastructure are in a much better position to launch initiatives rapidly and to exploit emerging opportunities. Lowers software development, support and maintenance cost Reduces complexity in IT infrastructure Flexibility to make, buy or outsource solutions
   • Layers
     • Application Layer
       • C2B e-commerce  B2B e-commerce  C2C e-commerce  C2G e-commerce
     • Middlemen Services Layer
       • Value-added networks: VAN provides communication channels among supply chain and trading partners by allowing the transmission of data and its translation between formats
       •  Digital signature certifying authority eg (Globalsign): Authentication – since your third-party validated certificate was used to apply the signature, recipients know it was actually you who signed it Non-repudiation – since your certificate was used to sign the document, you cannot later claim that it wasn’t you who signed it Message integrity – when the signature is verified, it checks that the data in the document matches what was in there when the signature was applied. Even the slightest change to the original document would cause this check to fail.
       •  Electronic payment schemes/ Electronic cash Because your website will need to accept online payments, you must find a provider who can host your website in a Payment Card Industry (PCI) compliant environment.
     • Messaging Layer
       • Digital encryption standard  Advanced encryption standard  Public key encryption  Digital signature  Electronic data interchange
       • Security and privacy tools & techniques Access controls Authentication Firewalls Encryption Digital signatures Public key infrastructures Privacy policies
     • Network Services Layer
       • useful tools to help individuals to undertake their activities on E-Commerce surroundings. Software agents create different paths for communication. Software agents increase the effectiveness and efficiency in several levels of market processes.
       •  E-mail  World wide web services; browsers  Hyper-text transfer protocol: http  Hypertext markup language: html  Extensible markup language: XML  Search engines  Software agents
     • Logical Layer
       • defines protocols to communicate logically between computers connected by the physical network
       • Protocols for Secure Electronic Commerce: S-HTTP (Secure HyperText Transfer Protocol) can only protect HTTP exchanges. SSL (Secure Sockets Layer) is a general protocol that can be applied to secure any exchanges between two points. SET (Secure Electronic Transaction) protocol, which was developed by Visa and MasterCard is exclusive to bankcard transactions. WTLS is the Wireless Application Protocol (WAP) Forum’s approach to secure transactions in mobile networks (Wireless Application Protocol Forum, 1999).
     • Physical Layer
       • Local area networks Private communication networks Optical fibre and coaxial cable networks Routers Satellite-based networks Cellular networks  Wireless networks

3. Readiness of Implementation

   • Do we have standards across the enterprise? Can we buy it? Do we have the technological infrastructure What do we need to do to create a businesssmart technology organization and a technologically smart business organization? Do we insist on simplicity, standardization, and flexibility in every corner of our e-commerce environment? Are the talents of the people across the enterprise optimally harnessed? Are our solutions flexible enough to accommodate change? Are solutions customizable to our customer’s needs?
