Chapter 15. Case Study: Car Parts Supply Chain

This chapter discusses a business-to-business (B2B) e-commerce example illustrating a hypothetical supply chain relationship among a car dealer, the manufacturer, and a part supplier. This example is based on the one contained in [WS Architecture 2003]. The example shows how the Web services protocol stack enables secure, reliable, and transactional interactions in a B2B scenario. In this example, the dealer and supplier access Web services exposed by a car manufacturer, which enables them to efficiently maintain the supply of car parts that consumers need. The interactions also involve accessing internal applications, some of them exposed as Web services. Quality of service protocols are enabled in each of these interactions as required.
