DIV-2 Information model (UPDM - DoDAF aliases)
Creation
To create a DIV-2 Information Model:
• Right-click the Logical Data Model that is to own the DIV-2 Information Model, point to New, point to DoDAF, point to Data and Information, and then click DIV-2 Information Model.
Purpose
On a DIV-2 Information Model:
• Create Association Of Information and Details relationships.
• Create Rule (Operational) 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 Notation of Elements that Appear on All Product Diagrams.
Association Of Information
To create an Association Of Information: click the appropriate 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 owning Entity Item. From the Select Type dialog, create or select the element that is 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 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.
Logical Data Model
To create a Logical Data Model: click the Logical Data Model button, and then click in free space on the diagram.
To populate elements from a Logical Data Model: add the Logical Data Model to the diagram, and then populate those elements from the Logical Data Model.
Rule (Operational)
To create a Rule (Operational): click the Rule (Operational) button, and then click in free space on the diagram.
To apply a Rule (Operational) to an Exchange Element or Entity Item on the diagram: click the Note Link button, click the Rule (Operational), and then click the Exchange Element or Entity Item to which the Rule (Operational) applies.
The following sections provide information about how a DIV-2 Information Model is used in the model.
