DIV-3 Physical data model (UPDM - DoDAF aliases)
Creation
To create a DIV-3 Physical Data Model:
• Right-click the Internal Data Model that is to own the DIV-3 Physical Data Model, point to New, point to DoDAF, point to Data and Information, and then click DIV-3 Physical Data Model.
Purpose
On a DIV-3 Physical Data Model:
• Create Association Of Information and Details relationships.
• Create Rule (System) elements and apply them to Exchange Element and Entity Item elements.
• Define inheritance between Exchange Element elements and Entity Item elements.
Diagram Elements
For information about showing compartments on diagram symbols, setting up default view options and adding existing elements to the diagram, see the following topics:
For information about the creation and appearance of elements that can be shown on all Product diagrams (Representation, Definition, Information, Metadata, Overlap and Same As elements), see Creation and appearance of elements that appear on all product diagrams (UPDM - DoDAF aliases).
Association Of Information
To create an Association Of Information: click the required Association Of Information button, click the source Entity Item, and then click the destination Entity Item.
Details
To create a Details: click the Details button, click the source Entity Item, and then click the destination Exchange Element.
Entity Attribute
To create an Entity Attribute: click the Entity Attribute button, and then click the Entity Item that is to own the Entity Attribute. From the Select Type dialog, select or create the type of the Entity Attribute, or create an untyped Entity Attribute.
Entity Item
To create an Entity Item: click the Entity Item button, and then click in free space on the diagram.
Use:
• Details relationships to link the Entity Item to related Exchange Element elements.
• Association Of Information relationships to link the Entity Item to related Entity Item elements.
• UML Generalizations to define Entity Item inheritance.
Exchange Element
To create an Exchange Element: click the Exchange Element button, and then click in free space on the diagram.
Use Details relationships to link the Exchange Element elements to related Entity Item elements.
Generalization (UML item)
To create a Generalization: click the Generalization button, click the sub element, and then click the super element. The types of the super and sub elements must be the same.
You can define inheritance for Entity Item and Exchange Element elements.
Internal Data Model
To create an Internal Data Model click the Internal Data Model button, and then click in free space on the diagram.
To populate elements from an Internal Data Model: add the Internal Data Model to the diagram, and then populate those elements from that Internal Data Model.
Rule (System)
To create a Rule (System): click the Rule (System) button, and then click in free space on the diagram. Use the Full Text property to specify the text of the Rule (System).
To apply a Rule (System) to an Entity Item and Exchange Element on the diagram: click the Note Link button, click the Rule (System), and then click the Entity Item or Exchange Element to which the Rule (System) applies.
The following sections provide information about how a DIV-3 Physical Data Model is used in the model.
