Introduction to Web Services
Web Services can make your applications Web applications.
Web Services are published, found and used through the Web.
What You Should Already Know
Before you continue you should have a basic understanding of the following:
What are Web Services?
- Web services are application components
- Web services communicate using open protocols
- Web services are self-contained and self-describing
- Web services can be discovered using UDDI
- Web services can be used by other applications
- XML is the basis for Web services
How Does it Work?
The basic Web services platform is XML + HTTP.
The HTTP protocol is the most used Internet protocol.
XML provides a language which can be used between different platforms and
programming languages and still express complex messages and functions.
Web services platform elements
- SOAP (Simple Object Access Protocol)
- UDDI (Universal Description, Discovery and Integration)
- WSDL (Web Services Description Language)
We will explain these topics later in the tutorial
The Future of Web services
Don't expect too much, too soon.
The Web Services platform is a simple, interoperable, messaging framework.
It still misses many important features like security and routing. But, these
pieces will come once SOAP becomes more advanced.
Hopefully, Web services can make it much easier for
applications to communicate.
