Use Case Diagrams - UML (Thanks to Helen Albanese for the starting point for this brief presentation)

Symbols Use case symbol – process Labeled with a noun-verb phrase

Symbols Actor/Role -- i.e., external entities May be a person or not (e.g., web server) Actor/Role

Symbols “Include” Relationship  Denotes the functionality of one use case with another use case.  The dotted arrow is drawn from the base case to the included case. >

Symbols “Extend” Relationship Extends the use case to denote optional behavior or alternative method of accomplishing task. The dotted arrow is drawn form the extended case to the base case. >

Symbols Association Connects the Actor(s) with the relevant processes (use case). *
