Creating composite use cases<br />
Lesson 2: Creating Your First Use Case Diagram<br />
34<br />
If you want to delete only the graphic representation of an object,<br />
but not the KnowledgeBase object itself, you can use the Graphics<br />
option on the Terminate submenu. Alternatively, you can use the<br />
Delete key on your keyboard or the Delete Graphics option on the<br />
Edit menu.<br />
Tip<br />
If you accidentally delete an object you want to keep, select<br />
Undo on the Edit menu to recreate it. Alternatively, if you’ve<br />
deleted only the graphic, you can recreate it by holding down the<br />
Control key while you use the tool with which you originally<br />
created the object.<br />
Creating composite use cases<br />
Use cases that contain<br />
other systems<br />
Composite use cases are use cases that incorporate one or more<br />
additional systems. In your Employee Hiring System use case<br />
diagram, you’ll include a composite use case representing a<br />
subsystem within the Employee Hiring system. In Lesson 3,<br />
“Getting More Specific about Your Hiring System,” you’ll create a<br />
second use case diagram to show the details of this composite use<br />
case.<br />
What you do To create a composite use case:<br />
1 In the Use Case Diagram Tools tool folder, click and hold on the<br />
Composite Use Case tool.<br />
2 Move your cursor below the Screen Resumes use case and release<br />
the mouse button to create the new composite use case graphic.<br />
3 Call your composite use case Hire Employees. Type this name<br />
and then click on the window background to close the edit box.
