The technical facet is demonstrated from perspectives of architectures, standards, and system analysis. The business requirements and application scenarios are exemplified in knowledge sharing, marketing services, and procurement processes. The evaluation approaches are introduced for assessment of system performance and information quality. Conclusions with future trends are illustrated in three aspects — from tangible to intangible access, from internal to external coordination, and from physical to virtual application.
