Agenda


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 interfacesEach 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 beforeA Web Service is a simple, reliable way to blend

existing systems with new applications and services

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


Web Service ComponentsWSDL - Example



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

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.

Web Services Adapter

Released with WebFOCUS 5.3Web Services Adapter allows WebFOCUS to directly

interact with a Web ServiceAble to create a report to read data returned from a

Web ServiceAble to pass parameters to a Web Service for

reportingAble to pass parameters to a Web Service for

updating data within an applicationAble to consume a WSDL fileJoin Web Services to Other Web Services or other

Tables (eg. SQL Server, ORACLE, Teradata)

Basic Functionality



Reads a WSDL file and creates the Connection information in EDASPROF

Reads a WSDL file and creates the Master and Access file for a particular Web Service function

New suffix: Suffix=SOAP1st Segment of the Master contain the input

parametersData Types get mapped to default Formats (USAGE

and ACTUAL)Arrays of output get mapped to multiple segments
