Checking a Data Model

The data model is a very flexible tool, which allows you quickly to develop your model without constraints. You can check the validity of your Data Model at any time.

A valid Data Model conforms to the following kinds of rules:

You can check your model in any of the following ways:

The Check Model Parameters dialog opens, allowing you to specify the kinds of checks to perform, and the objects to apply them to. The following sections document the Data Model -specific checks available by default. For information about checks made on generic objects available in all model types and for detailed information about using the Check Model Parameters dialog, see Core Features Guide > Modeling with PowerDesigner > Objects > Checking Models.
