Generating an XML model from an Object-Oriented Model
190 PowerDesigner
You can generate an OOM into an existing XML model.
If you choose to update an existing XML model when the current OOM has
never been generated, the Select model dropdown listbox is empty by default.
You have to click the Ellipsis button to display the Select a model dialog box
in which you can select a model. The Workspace Location and Physical Path
columns provide more information about the model location in the workspace
and the file path to help you choose the XML model. You can also use the
tooltip in the dropdown listbox to verify the location and path of the model.
To update an existing XML model, you must indicate the following
parameters:
Parameter Description
Select model Existing XML model. The OOM is generated into an
XML model. This XML model is merged with the
existing XML model to create an updated XML model.
The dropdown listbox displays already generated
models. The Ellipsis button lets you select models
opened in the workspace
XML language Current XML language definition for the XML model
Preserve modifications Allows a comparison and merge of the newly generated
XML model (default XML model) with the currently
selected XML model
Clearing the Preserve modifications check box
If the Preserve modifications check box is not selected, PowerDesigner
automatically replaces the existing XML model with the newly generated
XML model.
If you want to choose which objects to add or delete from the model to be
merged, you must select Preserve modifications to compare and merge the
two XML models.
