Web services (obsolete)
Web services are loosely defined as the use of Internet technologies
to make distributed software components talk to each other without human
intervention. The software components might perform such business logic as
getting a stock quote, searching the inventory of a catalog on the
Internet, or integrating the reservation services for an airline and a car
rental agency. You can reach across the Internet and use preexisting
components, instead of having to write them for your application.
A PowerBuilder application can act as a client consuming a Web
service that is accessed through the Internet. Through use of SOAP and
WSDL, a collection of functions published remotely as a single entity can
become part of your PowerBuilder application. A Web service accepts and
responds to requests sent by applications or other Web services.
