  • B2B has been around almost over 30 years. It started on proprietary networks between companies. Recently there is sufficient technology to allow companies build up interorganizational networks over the Internet. B2C It bacame very popular after the Internet arrives.

The system yielded reduced cost, just in time inventory management. And it allows locking in trading partners. EDI = Chrysler required its parts suppliers to participate its interchange data network Electronic Markets : Rather than having links only link existing trading partners in tightly coupled arrangements, electronic market could conceivably include large number of buyers and seller

  • Data leaves your computer begins its journey over the network, in this case over the Internet which is a public network. Someone can interrupt this flow and obtain your data.
