Similar to XML sources and targets, web service source and target definitions are organized into XML views. XML views are groups of columns that represent the elements and attributes defined in the input and output messages.

When you import source and target definitions, the Designer generates XML views based on the elements in the input or output messages defined in the WSDL. It also generates views for mime attachments to the input or output messages.

When you create web service source and target definitions, the Designer creates XML views based on the columns defined in the relational or flat file sources or targets or the columns that you manually define.
