Drag use case into the use case diagram

Note: You can also use the tool palette to create associations.

Create use cases (this sequence is similar to creating actors):

–Expand 00 Enterprise Level → Use Cases → ${Building Blocks}.

–Right-click ${use.case} and select Copy.

–Right-click the Use Cases folder and select Paste.

–Right-click the new ${use.case} folder that you pasted and select Edit → Find/Replace (or press Ctrl-f).

–Put ${use.case} in the Search string field and click Replace.

–Type RegisterForAlert in the With field and click Replace All.

–Repeat these steps to create use cases named GetLocalForecast and GetRawWeatherData.

Note: Use cases are not placed into the context diagram. Relationships between actors and the use case are created in the use case diagram.

Create associations between the use cases and the actors:

–In the Project Explorer, expand the Use Case Diagrams folder.

–Open (double-click) the Use Case Diagram.

–In the Project Explorer, expand the GetRawWeatherData folder.

–Select the GetRawWeatherData use case and drop it into the use case diagram (Figure 6-37).
