PBTV Webinar: Creating and Consuming Web Services Based on SQL Queries in PowerBuilder

PBTV has all your best straight from this year's PowerBuilder Developer's Conference. Come check out Tuesday October 30, 10AM PST on PBTV, come check out George Mikhailovsky present on 'Creating and Consuming Web Services Based on SQL Queries in PowerBuilder.'
Unlike direct connections to the database, Web services can be managed and secured outside of an application and used by any Website or client/server, Web, or mobile application. A PowerBuilder application then can use Web services to return data sets as data sources of the application's DataWindows. This facilitates the incorporation of PowerBuilder applications and Web services into a cloud computing environment. This session explains and demonstrates how to:
Build a data store based on a chosen query and structure that can be used for constructing Web service output.
Create a class (NVO) as a wrapper of a Web service with the necessary Get_...()? functions that populate arrays of structures from respective data store(s).
Deploy a created Web service to an IIS Web server including the creation of a WSDL file.
Create a DataWindow with a Web service as a data source.
Choose a proper Web service and find its desired method (Get_...()? function).
Select a proper parameter from the chosen Web service method and finalize the created DataWindow to solve hidden problems with the string data type.
