Summary
In this chapter we have gone step-by-step and developed a Web services-based enterprise procurement application. We discussed both sides of the application—the client application that consumes Web services to present a coherent value-added functionality as well as the individual Web services.
We also implemented the entire system by using only the technologies of the core Web services platform—SOAP and WSDL. In the next chapter, we build on and extend this application, using the technologies and standards discussed in the second section of this book, and develop an enterprise-class system that supports transactions, workflow, mobility, and security.
