Fundamentals of E-Business
E-business is the conduct of business processes (buying, selling, servicing, collaborating) over digital networks; e-commerce is the narrower subset of buying and selling transactions online.
Four common e-commerce models: B2B (business to business), B2C (business to consumer), C2B (consumer to business), C2C (consumer to consumer); B2G and G2C involve government.
Transaction revenue model types include sales, subscription, advertising, transaction fee, and affiliate; a firm may combine several revenue streams.
E-business infrastructure layers: network (Internet, intranet, extranet), hardware/servers, software applications, and data/security services.
EDI (Electronic Data Interchange) exchanges standardized business documents between trading partners; XML-based web services extend EDI to the Internet.
Payment systems: credit/debit cards, e-wallets, bank transfers, and digital currencies; PCI DSS is the security standard for card data.
Key security goals are confidentiality, integrity, availability, authentication, and non-repudiation; SSL/TLS and digital certificates support them.
M-commerce is e-commerce conducted via mobile devices; it relies on mobile networks, location services, and mobile payment apps.
Disintermediation removes intermediaries from a value chain (e.g., manufacturer selling direct), while reintermediation adds new online intermediaries such as aggregators.
