While Electronic Commerce is believed to provide new opportunities and environments toward the information society, not many companies have achieved successful construction of Electronic Commerce systems regarding their own technology factors and business process types. This work provides a brief review of Electronic Commerce information infrastructure based on the technology architecture developed. Three major technologies-telecommunication, information processing, and process enhancement - support the architecture, and each major technology consists of its technical enablers. Also, the application factors of Electronic Commerce are defined and analyzed in term of inter-enterprise, intra-enterprise, and enterprise-consumer interactivity. Finally, the implementation strategy is drawn with respect to the technology architecture and three application types.
