Agenda

A Web Service is a software system designed to support interoperable machine-to-machine interaction over a network.

Web services are small, reusable applications that help computers from many different operating system platforms work together by exchanging messages.

What is a Web Service?

Web services are based on industry protocols that include XML (Extensible Markup Language),

SOAP (Simple Object Access Protocol), and WSDL (Web Services Description Language).

These protocols help computers work together across various platforms and programming languages.

Why web service ?

Terminology

Web Service architecture

Service oriented architecture

Its lightweight XML-based messaging protocol  used to encode the information in  web service request and response messages before sending them over a network

SOAP messages are independent of any  operating system  or protocol and may be transported using a variety of Internet protocols

What is SOAP ?

Platform independent Language independent Based on XML Simple and extensible Communication protocol Communication between applications Format for sending messages Designed to communicate via Internet

Features of SOAP

SOAP message format

WSDL is an XML-based language used to define Web Services and describe how to access them.

WSDL is an XML based protocol for information exchange in decentralized and distributed environments

WSDL is the standard format for describing a web service.

What is WSDL?

WSDL is a language for describing how to interface with XML-based services.

WSDL definition describes how to access a web service and what operations it will perform.

WSDL is the language that UDDI uses. WSDL was developed jointly by Microsoft and IBM.
