Attaching an expression to a business rule
A business rule typically starts out as a description. As you develop your model and analyze your business problem, you can complete a rule by adding a technical expression.
Each business rule can include two types of expression:
♦Server
♦Client
Expressions are used essentially in a CDM or a PDM.
∃For more information on expressions, see the chapter Using Business Rules in the PowerDesigner PDM User’s Guide.
