A graphical synonym is an additional symbol for an object. It has no specific definition in itself but takes the one of the object it represents.
By reproducing the same object at different places in the diagram, graphical synonyms can improve the readability of the diagram as links become shorter.
You can create as many graphical synonyms as you want within the same diagram.
You can create graphical synonyms of graphical synonyms as they are graphical representations of the same object.
In the diagram, the graphical synonym displays the name of the object followed by a colon and the number of the occurrence.
This class is a graphical synonym for the class Printer.
Moving graphical |
A graphical synonym exists in a diagram as long as the object it represents |
|
synonyms |
also exists. |
|
|
If you move a graphical synonym from a package to another, it is moved to |
|
|
the target package and shortcuts are created for the remaining graphical |
|
|
synonyms in the source package. |

You can move an object from package to package using the drag and drop feature.
Moving objects is different from cutting and pasting items, since you do not duplicate objects.
Moving restrictions are the following:
♦Models must be compatible (same DBMS for PDM or same language for OOM)
♦Global objects (business rule, domain, storage etc.) cannot be moved into a sub-package

For entities containing data items, the following situations can occur when you move the entity:

When you move an object from a package to another, linking objects that you move keep their links in the target package and a shortcut is usually created in the source package. The general rule being that conceptual modeling must be preserved.
Shortcuts creation rules in PowerDesigner also apply to moving objects between packages.
