NOV-7 Information model (UPDM - NAF aliases)
Creation
To create an NOV-7 Information Model:
Right-click the Logical Data Model that is to own the NOV-7 Information Model, point to New, point to NAF, point to Operational, and then click NOV-7 Information Model.
Purpose
On an NOV-7 Information Model:
Create Entity Relationship and Details relationships.
Create Operational Constraint 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 (Alias, Definition, Information, Metadata, Overlap and Same As elements), see Creation and appearance of elements that appear on all product diagrams (UPDM — NAF aliases).
To create a Details: click the 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.
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.
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.
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.
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.
To create an Operational Constraint: click the 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.
The following sections provide information about how an NOV-7 Information Model is used in the model.
