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 window opens, allowing you to specify the kinds of checks to perform, and the objects to apply them to. For detailed information about this window and correcting problems reported, see "Checking a Model" in the Models chapter of the Core Features Guide.

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, see "Checking a Model" in the Models chapter of the Core Features Guide.
