The reverse engineering feature reads the PowerBuilder extended attributes contained in a database and writes them into the appropriate tables and columns in a PDM.
During reverse engineering, certain reversed extended attributes are compared with the translated default values in the PowerBuilder extended model definition. It these attributes match, the reversed value is replaced by the default value from the extended model definition.
For more information about objects translated during reverse engineering, see Generating PowerBuilder extended attributes.
This automated process uses the PowerDesigner generation template language (see the Customizing Generation with GTL chapter in Customizing and Extending PowerDesigner).
