Chapter 3 Using Business Rules in a CDM

Creating a business rule in a CDM

Before you create business rules, formulate your rules by asking yourself the following questions:

• What business problems do I want to address?
• Are there any procedures that my system must respect?
• Do any specifications dictate the scope of my project?
• Do any constraints limit my options?
• How do I describe each of these procedures, specifications, and constraints?
• How do I classify these descriptions: as definitions, facts, formulas, or validation rules?

To create a business rule in a CDM:

1. Select Model→Business Rules to display the List of Business Rules. It displays the business rules defined for the model.
   
2. Click a blank line in the list.
   
   or
   
   Click the Add a Row tool.
   
   An arrow appears at the beginning of the line.
3. Type a name and a code for the business rule.
4. Click Apply.
   
   The creation of the new business rule is committed.
5. Click the new business rule line.
   
   An arrow appears at the beginning of the line.
6. Click the Properties tool.
   
   or
   
   Double click the arrow at the beginning of the line.
   
   The property sheet for the new business rule appears.
7. Click the General tab and select a business rule type from the Type dropdown listbox.
