3. Copyright 2007, Information Builders. Slide 3 Web Services Overview What are Web Services? A Web Service  is a procedure that has all the logic, and access requirements to perform a given task when called to do so.  uses the internet as an huge Application Server.  provides the calling procedure with the necessary information about the web service through an XML document known as the WSDL.

4. Copyright 2007, Information Builders. Slide 4 Web Services Overview What makes Web Services so desirable? Web Services are:  reusable, self-contained, self-describing, application programs, providing a specific functionality.  purposely built to be executed, described, and discovered, over the internet, regardless of enterprise boundaries and firewalls. (Still very efficient inside an intranet or network!)  provide a layer of abstraction to user, allowing them not to worry about “physical” details such as  Programming languages  Communication protocols  support a concept of a “Registry” where users can “discover” web services that may be of use to them

5. Copyright 2007, Information Builders. Slide 5 Web Services Overview What makes Web Services so flexible? Use of well known standards for:  SOAP (Simple Object Access Protocol) – Message format for invoking Web Services.  WSDL (Web Service Definition Language) – A standard for describing Web Services.  XML (Extensible Mark-up Language) – A platform/operating system independent document format that SOAP and WSDL use. (XML is both computer AND people friendly!)  The Registry (not fully standardized) – a repository of “categorized” registered Web Services (similar to the Yellow Pages)  UDDI – Most common registry

6. Copyright 2007, Information Builders. Slide 6 Web Services Overview How are Web Services used? Web Services are used  to perform application-to-application integration over the Web.  as business process interfaces.  as a point of interaction to give input and receive output from a business process.  to allow previously incompatible applications to interoperate on the Web regardless of language, platform, and operating systems.  as a standalone function that can be called by many different applications.

7. Copyright 2007, Information Builders. Slide 7 Web Services Overview What are the benefits of using web services? Web Services  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.  are self-describing (WSDL,UDDI).  allow developers to develop applications much faster than before  are a simple, reliable way to blend existing systems with new applications and services

8. Copyright 2007, Information Builders. Slide 8 Using iWay to create a Web Service iWay components needed To create an iWay web Service you will need the following three iWay products installed and configured:  iWay Service Manager (iSM)  iWay Explorer (iE)

9. Copyright 2007, Information Builders. Slide 9 iWay Service Manager  iWay Service Manager (iSM)  Host for Service-Oriented Architecture  Supports configuring iWay Adapters of all types  J2SE Environment (Server)  Supports other iWay Components  iWay Transformer  iWay Designer  iWay Explorer

10. Copyright 2007, Information Builders. Slide 10 iWay Explorer  iWay Explorer  Allows exploration of EIS via the adapter  Creates XML Schemas for Request/Response (Service)  Creates XML Schemas for Result (Event)  Consistent view of all Enterprise Systems

11. Copyright 2007, Information Builders. Slide 11 Using iWay to create a Web Service iWay Business Services Provider  The SOAP End Point for iWay Business Services  HTTPS Server that exchanges SOAP messages with Web Service client applications  Loads, or calls, necessary iWay Adapter based on SOAP message  Maintains an IBS Repository (db) where physical connectivity and security info needed to run the backend object  A form of a Registry  Portable – can be installed on all major computing platforms  Has Web Console (default port 9999)

12. Copyright 2007, Information Builders. Slide 12 Describing a Web Service to WebFOCUS WebFOCUS components needed To describe a web Service to WebFOCUS you will need the following two WebFOCUS products installed and configured:  WebFOCUS Reporting Server  WebFOCUS Web Services Adapter

13. Copyright 2007, Information Builders. Slide 13 Describing a Web Service to WebFOCUS WebFOCUS Reporting Server WebFOCUS Reporting Server  Holds metadata for the data sources WebFOCUS can access, and controls access to those data sources.  It is responsible for executing the queries against these data sources and retrieving and formatting the query results, which it then passes to the WebFOCUS client.  It provides multiple data adapters that give users access to data in many different types of data sources.

14. Copyright 2007, Information Builders. Slide 14 Describing a Web Service to WebFOCUS WebFOCUS Web Services Adapter Overview WebFOCUS Web Services Adapter:  allows WebFOCUS to directly interact with a Web Service.  is able to create a report to read data returned from a Web Service.  can pass parameters to a Web Service for reporting.  can pass parameters to a Web Service for updating data within an application.  is able to consume a WSDL file.  can join Web Services to Other Web Services.  can join Web Services to other Table types (e.g.. SQL Server, ORACLE, DB/2).

15. Copyright 2007, Information Builders. Slide 15 Describing a Web Service to WebFOCUS How does the Web Services Adapter work? WebFOCUS Web Services Adapter:  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.  has a new suffix: Suffix=SOAP.  1 st Segment of the Master contain the input parameters.  Reads Data Types and maps them to default Formats (USAGE and ACTUAL).  Arrays of output get mapped to multiple segments.
