To integrate PowerCenter with web services, you can create web service source definitions, target definitions, and Web Services Consumer transformations. Web service source and target definitions provide the metadata for web service sources and targets. Web Service application connections enable the PowerCenter Integration Service to read data from web service sources and targets. Web Services Consumer transformations let the PowerCenter Integration Service use a web service to transform data.
You use the Designer to create web service source and target definitions and Web Services Consumer transformations. To create web service source and target definitions and Web Services Consumer transformations, the Designer imports metadata from a WSDL file. WSDL files describe web services and web service operations.
When you run a workflow to read or write web service data or transform data using a web service, the PowerCenter Integration Service connects to the server that hosts the web service defined in your mapping.
