In PowerDesigner, each package can be a namespace. It is however possible to expand the namespace to the parent of a given package. You can cascade the expansion until you reach the level of the model itself.
Objects that appear in the Browser obey the general rules that follow:
|
In Browser |
Namespace |
Uniqueness rule |
|---|---|---|
|
Objects directly under a package or a model (table, process, class) |
Model |
Unique name and code in model |
|
Package |
Unique name and code in package |
|
|
Objects under parent object (column, attribute) |
Not applicable |
Unique name and code in parent |
|
Linking objects (reference, relationship) |
Not applicable |
Unique name and code between same end objects (i.e., parallel links with same name and code are not allowed between same end objects) |
However, you may encounter some exceptions to those rules. For example only the code of a reference allows to identify the object in the entire model, when the "Unique code" option is selected in the Model Options dialog box. PowerDesigner warns you when a general rule is not respected.
