In this chapter, I've focused on web services, covering SOAP, WSDL, and UDDI. Refer to the W3C website and to the UDDI (www.uddi.org) and ebXML (www.ebxml.org) sites for more information in the area of business-oriented web services. I didn't delve much into these non-technical issues, but they were worth mentioning.
You should have noticed in this chapter that Delphi is strong player in the area of web services, with a powerful, open architecture. You can use web services to interact with applications written for the Microsoft .NET platform; Delphi has much to offer for this architecture, because it includes a Delphi for .NET preview (covered in the two final chapters of the book).
Chapter 24, "The Microsoft .NET Architecture from the Delphi Perspective," is focused on the .NET platform; Chapter 25, "Delphi for .NET Preview: The Language and the RTL," covers the new Delphi compiler.
