An operation is an artifact that specifies the information
required to invoke a flow, a nonterminal application, or an outbound Web service.
An operation is different in content and purpose from a screen operation:
- An operation contains the information required to invoke a flow,
a nonterminal application, or an outbound Web service.
- A screen operation contains the information required to handle
a particular application screen of a terminal application (see Working with screen operations files).
