Chapter 5 Using the PowerDesigner Interface

Applying a business rule to an object

A business rule is a rule that your business follows. A business rule could be a government-imposed law, a customer requirement, or an internal guideline.

Business rules complement model graphics with information that is not easily represented graphically.

You can add business rules to the definition of the current object from its property sheet.

Note   U Column in the List of business rules
When you apply a business rule to an object, the U (Used) column beside this business rule is automatically checked in the List of business rules to indicate that the business rule is used by at least one object in the model. The U column allows you to visualize unused business rules. You can then delete them if necessary.

Steps To apply a business rule to the current object:

  1. Open the property sheet of an object and click the Rules tab.
  2. Click the Add Rules tool.
  3. Select one or more business rules in the selection dialog box.
  4. Click OK in the selection dialog box, the rules appear in the list of rules.
  5. Click OK to return to the model diagram.
