Introduction to Web Services

Introduction to Web Services

Web Service is a network-based, distributed, modular component that performs specific tasks and adheres to specific technical specifications that enable Web Service to interact with other compatible components.

Web Services makes your application a web application.

Web Services is published, found, and used over the Web.

Before you move on, you need to have a basic understanding of the following:

What is Web Services?

• Web Services is an application component
• Web Services uses open protocols to communicate
• Web Services is independent (self-contained) and self-describeable
• 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 underlying Web Services platform is XML and HTTP.

HTTP protocols are the most commonly used Internet protocols.

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

Elements of the Web services platform:

• SOAP (Easy Object Access Protocol)
• UDDI (Universal Description, Discovery and Integration)
• WSDL (Web services description language)

We'll cover these topics later in this tutorial.
