Copyright 2007, Information Builders. Slide 3 What is a Web Service? A self-contained, modular application that can be described, published, located, and invoked over the Web. Platform-neutral and based on open standards, Web Services can be combined with each other in different ways to create business processes that enable you to interact with customers, employees, and suppliers. Definition

Web Services use the Web to perform application-to- application integration Web Services are business process interfaces Each Web Service is a point of interaction to give input and receive output from a business process Allow previously incompatible applications to interoperate on the Web regardless of language, platform, and operating systems A standalone function that can be called by many different applications Basic Concepts

Reduce complexity by encapsulating business processes into reusable components Improve interoperability by acting as a wrapper around legacy or platform-specific applications Promote true interoperability through platform and implementation neutrality A Web service can be self-describing (WSDL,UDDI) Develop applications much faster than before A Web Service is a simple, reliable way to blend existing systems with new applications and services Usage Benefits

Copyright 2007, Information Builders. Slide 11 Web Service Components Web Services Description Language (WSDL) The standard format for describing a Web Service. Expressed in XML, a WSDL definition describes how to access a Web Service and what operations it will perform A WSDL document provides information on the data being exchanged, the sequence of messages for an operation, protocol bindings (HTTP), and the location of the service A WSDL document defines services as a collection of endpoints (location within a context to which remote service requests can be directed) WSDL

Slide 13 Web Service Components Universal Description Discovery and Integration (UDDI) UDDI is an XML-based registry for businesses worldwide to list themselves on the Internet for Web Services and for other electronic and non-electronic services Allows businesses to list themselves by name, product, location, or the Web Services they offer (Yellow Pages) Service consumers can use UDDI to discover services that suit their requirements ( UDDI

Slide 16 Web Service Components Simple Object Access Protocol (SOAP) A way for a program running in one operating system to communicate with a program in the same or another operating system A standard for exchanging XML based messages (Request/Response) normally using HTTP SOAP Envelope identifies an XML document as being a SOAP message and encapsulates all the other parts of the message SOAP Header is optional and can be used to extend the message syntax independently for a particular application SOAP Body where application specific data is placed. Encoding rules of the Envelope describe what syntax was used to encode data in the Body. SOAP
