Defining OOM generation options

You can set the following general generation options from the Detail page:

Option	Description
Check Model	When selected, checks the model before generating the OOM, and stops generation if an error is found
Save Generation Dependencies	When selected, PowerDesigner keeps track of the identity of the origin of each generated object. It is useful when merging two OOM which have been generated from the same CDM. Objects can be compared and recognized as the same object, even if the object has been modified in the target OOM. If not selected, origin objects have no link with generated objects
OOM/CDM Mapping	When selected, allows to define the current CDM as the data source of the generated OOM and to create object correspondence between source CDM and target OOM. If you select the OOM/CDM mapping option, the Save Generation Dependencies option is automatically selected because OOM/CDM mapping uses object identifying numbers. You cannot deselect the Save Generation Dependencies option as long as the OOM/CDM mapping option is selected
Convert Names into Codes	When selected, object codes are generated from names using the corresponding conversion script. This is useful when generating models with very different naming conventions since conversion macros are used to modify codes. For example a Java class attribute code may be "customerName" whereas a PDM table column may be "CUSTOMER_NAME". With this option selected, both objects will have their codes generated from their names. If you do not select this option, generated object codes will be copied from original object codes
Enable transformations	This button is used to activate transformations during generation. When you click this button, the Pre-generation tab is displayed if the source model contains transformations. You can select the transformations to execute before generation. The Extended Model Definitions tab also is displayed for you to select extended model definition files to attach to the generated model. These files may contain post-generation transformations, in this case, the Post-Generation tab is displayed to let you select the transformations you want to be executed in the generated model. If the generation is an update, and the generated model contains extended model definitions with post-generation transformations, the Post-generation tab automatically is displayed as soon as you click the Enable Transformations button
Class Prefix	Prefix for a class. It can help identify a class in a model

Option

Description

Check Model

When selected, checks the model before generating the OOM, and stops generation if an error is found

Save Generation Dependencies

When selected, PowerDesigner keeps track of the identity of the origin of each generated object. It is useful when merging two OOM which have been generated from the same CDM. Objects can be compared and recognized as the same object, even if the object has been modified in the target OOM. If not selected, origin objects have no link with generated objects

OOM/CDM Mapping

When selected, allows to define the current CDM as the data source of the generated OOM and to create object correspondence between source CDM and target OOM. If you select the OOM/CDM mapping option, the Save Generation Dependencies option is automatically selected because OOM/CDM mapping uses object identifying numbers. You cannot deselect the Save Generation Dependencies option as long as the OOM/CDM mapping option is selected

Convert Names into Codes

When selected, object codes are generated from names using the corresponding conversion script. This is useful when generating models with very different naming conventions since conversion macros are used to modify codes. For example a Java class attribute code may be "customerName" whereas a PDM table column may be "CUSTOMER_NAME". With this option selected, both objects will have their codes generated from their names. If you do not select this option, generated object codes will be copied from original object codes

Enable transformations

This button is used to activate transformations during generation.

When you click this button, the Pre-generation tab is displayed if the source model contains transformations. You can select the transformations to execute before generation.

The Extended Model Definitions tab also is displayed for you to select extended model definition files to attach to the generated model. These files may contain post-generation transformations, in this case, the Post-Generation tab is displayed to let you select the transformations you want to be executed in the generated model. If the generation is an update, and the generated model contains extended model definitions with post-generation transformations, the Post-generation tab automatically is displayed as soon as you click the Enable Transformations button

Class Prefix

Prefix for a class. It can help identify a class in a model

For more information conversion scripts, see section Using a conversion script in chapter Managing models in the General Features Guide .

Check model before generation
If you select the Check Model option, the procedure to generate an OOM starts by checking the validity of the CDM . An OOM results when no errors are found. You can set check options by selecting Tools→Check Model.
