OV-7 Information model (UPDM - MODAF aliases)
Creation
To create an OV-7 Information Model:
• Right-click the
Logical Data Model that is to own the OV-7 Information Model, point to New, point to MODAF, point to Operational, and then click OV-7 Information Model.
Purpose
On an OV-7 Information Model:
• Create
Operational Constraint elements and apply them to Exchange Element and Entity Item elements.

To create a Details: click the 
Details button, click the source Entity Item, and then click the destination Exchange Element.
Details button, click the source Entity Item, and then click the destination Exchange Element.
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 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.
To create an Entity Item: click the 
Entity Item button, and then click in free space on the diagram.
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.
• Entity Relationship relationships to link the Entity Item to related Entity Item elements.
• UML Generalizations to define Entity Item inheritance.
To create an Entity Relationship: click the appropriate 
Entity Relationship button, click the source Entity Item, and then click the destination Entity Item.
Entity Relationship button, click the source Entity Item, and then click the destination Entity Item.
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.
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.
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.
To create a Logical Data Model: click the 
Logical Data Model button, and then click in free space on the diagram.
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.
To create an Operational Constraint: click the 
Operational Constraint button, and then click in free space on the diagram.
Operational Constraint button, and then click in free space on the diagram.To apply an Operational Constraint to an Exchange Element or Entity Item on the diagram: click the 
Note Link button, click the Operational Constraint, and then click the Exchange Element or Entity Item to which the Operational Constraint applies.
Note Link button, click the Operational Constraint, and then click the Exchange Element or Entity Item to which the Operational Constraint applies.The following sections provide information about how an OV-7 Information Model is used in the model.
