Overview of Web services
In this chapter, we focus on some of the architectural concepts that have to be considered in a Web services project. We define and discuss service-oriented architecture (SOA) and the relationship between SOAs and Web services.
We then take a closer look at Web services, a technology that enables you to invoke applications using Internet protocols and standards. The technology is called Web services because it integrates services (applications) using Web technologies (the Internet and its standards).
