business-to-consumer e-services applications. Major application functional modules comprised in the system framework include
consumer and personalized management, navigation and search,evaluation and selection, planning and design, community and
collaboration management, auction and negotiation, transactions
and payments, quality and feedback control, as well as communications and information distributions. System design and
implementation methods will be illustrated using an example.
Also explored are various potential e-services application domains
including e-tourism and e-investment.
