Chapter 8 Building Web Services

Web Services (PDM)

In PowerDesigner, web services are made of web operations which themselves contain web parameters and result columns:

Web operations specify the SQL statements used to retrieve data from databases
Web parameters are the parameters which appear in the SQL statements
Result columns are the columns in which the results are displayed

These objects have no symbols, but they appear in the Browser tree view.

This structure is compatible with the definition of web services in the supported databases.

Import Web service as service provider

You can import a web service as a service provider into a Business Process Model (BPM) to define the links between a concrete implementation of service interfaces and operations and their abstract definition.

For more information, see "Importing and exporting service providers" in the Building an Executable BPM: Working with Service Description Objects chapter of the BPM User's Guide .
