Service access (UPDM - NAF aliases)
Creation
To create a Service Access:
• From an Architectural Description or Service Description: right-click the Architectural Description or Service Description, point to New, point to NAF, point to Service, and then click Service Access.
• From an NSV-1 Resource Specification, NSV-4 Functionality Hierarchy, NSV-5 Function to Operational Activity/Service Function Definition or NSV-9 Technology and Skills Forecast Definition: click the Service Access toolbar button, and then click in free space on the diagram.
Appearance
When shown on an NSV-1 Resource Specification, NSV-4 Functionality Hierarchy, NSV-5 Function to Operational Activity/Service Function Definition or NSV-9 Technology and Skills Forecast Definition, a Service Access appears as follows:
When shown on an NSV-1 Resource Interaction Specification or NSV-2 System Communications Description, a Service Access appears as follows:
Relationships
The following relationships are of importance to a Service Access:
• UML Generalizations define Service Access inheritance ( NSV-1 Resource Specification).
• Forecast relationships link a Service Access to forecasted future Service Access elements.
• Implements relationships link a Service Access to the Node elements it implements.
• Is Capable Of Performing relationships to link a Service Access to the Function elements that can be performed by the Service Access.
• Used as a type for Concept Role, Known Resource, Node Port, Resource Port, Resource Role and Service Level Value Set elements.
• Used as a conveyed classifier for Operational Exchange elements.
The following sections provide information about how a Service Access is used in the model.
