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

Web services have two types of uses.

Reusable application components

There are things different applications need very often. So why make these over and over again?

Web services can offer application components like currency conversion, weather reports or even language translation as services.

Ideally, there will only be one type of each application component, and anyone can use it in their application.

Connect existing software

Web services help solve the interoperability problem by giving different applications a way to link their data.

Using Web services you can exchange data between different applications and different platforms.
