根据市场调查公司Forresster的估计,到公元2002年,全球企业间交易金额将达到3270亿美元;Cisco网络公司每天与零售商的网络交易金额已经超过1100万美元,通过网络交易所节省的成本,包括技术资源、渠道与行销,每年超过3.6亿美元以上。这类型的电子商务,主要依靠企业间网络(Extranet)完成。 和Intranet连结企业内部员工不同,Extranet串连的是上、下游企业的供应链关系,在办公自动化完成后,企业间的交易关系由手写发票转为电脑化文件,Extranet更将这些数字化的信息转为资料库,并以电脑连结。这些资料仅开放给企业授权的客户、供应商、内部人员查询,不像Internet提供网络上任何人都可浏览。 Extranet物美价廉,效益无限 Extranet并不是太复杂浩大的工程,当您利用FedEx网站查询你委托投递的包裹时,你已经进入了FedEx的Extranet里,现在我们能随时查询寄送包裹的最新状况,这主要是因特网的普及的结果。Extranet发展前的前身是电子资料交换(EDI,Electronic Data Interchange)。EDI系统是供应商与客户间的专线网络,由于成本高昂、系统复杂,仅有具备规模经济的大企业之间才可能设立,中、小企业根本无缘体验;其次,EDI系统变化弹性低,它有特定的订单、发票格式,不能随意更改。
According to market research firm Forresster, by 2002, global transactions between companies will reach 327 billion U.S. dollars. The daily network transactions between Cisco Networks and retailers have exceeded 11 million U.S. dollars. The costs saved through Internet exchanges include: Technical resources, channels and marketing, more than 360 million US dollars each year. This type of e-commerce mainly relies on an extranet. Different from intranet employees, Extranet connects the supply chain of upstream and downstream enterprises. After the office automation is completed, the transaction relationships among enterprises are converted from handwritten invoices to computerized documents. Extranet turns these digitized information For the database, and a computer link. The information is only open to the enterprise authorized customers, suppliers, internal staff inquiries, unlike the Internet to provide network anyone can browse. Extranet Affordable, Effective Extranet Extranet is not too complex and vast project, when you use the FedEx website for your entrusted delivery package, you have entered the FedEx Extranet, and now we can always check the latest status of the delivery package, This is mainly the result of the popularity of the Internet. Extranet predecessor before the development of electronic data exchange (EDI, Electronic Data Interchange). EDI system is a private network between suppliers and customers. Due to the high cost and complex system, only large enterprises with economies of scale can be established. Medium and small enterprises have no experience at all. Second, the flexibility of EDI system is low. A specific order, invoice format, can not be changed at random.
