Chapter 5 Working with Conceptual Data Models
When you check a CDM, you can define levels of severity for problems that Check model finds and have certain problems automatically corrected.
You can set a level of problem severity for each object parameter that is verified by the Check model. This severity level can depend on the degree of normalization that you want to achieve in a your model.
When you check a CDM, you can display an invalid parameter with one of two types of messages, depending on the degree of problem severity you assigned to that parameter:
| Message | Description |
|---|---|
| Error | Major problem that impedes database generation |
| Warning | Minor problem or recommendation |
You can choose to have certain problems corrected automatically by PowerDesigner. Automatic correction primarily fixes non-unique names in the CDM. However, before using automatic correction, make sure you understand how it will affect your model.
As automatic correction is not available for most object parameters, they must be corrected manually.
For more information on manual and automatic correction, see Object parameters verified by Check model.
You can use the following tools from the Check Model Parameters dialog box to set either an error or warning level of problem severity, and also if you want PowerDesigner to automatically correct an error:
| Tool | Indicates | Description |
|---|---|---|
|
Error | Indicates a major problem that impedes database generation |
|
Warning | Indicates a minor problem or recommendation |
|
Automatic correction | Indicates that PowerDesigner will correct the problem automatically |
