Chapter 11 Linking and Synchronizing Models

Linking a requirement to a design object

The following figure shows the links between the Requirements Model and other PowerDesigner models.

For more information on the RQM, see the Requirements Modeling guide.

You can link requirements to design objects to make sure that each action described in the RQM is implemented by an object during the development process. For example, the Internet Access requirement of the Cyberfridge example can be linked to a Web Service component in an OOM.

You can link a requirement to a design object in any of the following ways:

• Using the Add Links to Design Objects in the Traceability Links tab of the requirement property sheet.
• Using the Import Design Objects as Requirements command in the Requirements menu.
• Using the Export Requirements as Design Objects command in the Requirements menu.

When you link a requirement to a design object, a shortcut of the design object is automatically created in the RQM, on the Design Object sub-tab of the Dependencies tab of the requirement. You can click the Impact Analysis button to display the dependencies of the requirement:
