What are Web Services?

  • Web Services are application components.
  • Web Services communicate using open protocols.
  • Web Services are independent (self-contained) and self-descriptive.
  • Web Services can be discovered by using UDDI.
  • Web Services can be used by other applications.
  • XML is the foundation of Web Services.

How does it work?

The basic Web Services platform is XML + HTTP.

HTTP protocol is the most commonly used Internet protocol.

XML provides a language that can be used between different platforms and programming languages.

Elements of the Web Services Platform:

  • SOAP (Simple Object Access Protocol)
  • UDDI (Universal Description, Discovery, and Integration)
  • WSDL (Web Services Description Language)

We will explain these topics in the later chapters of this tutorial.

The Future of Web Services

Do not expect too much too soon!

The Web services platform is a simple messaging framework that can be operated together. It still lacks many important features such as security and routing. However, once SOAP becomes more advanced, these issues will be resolved.

Web services are expected to make application communication easier.
