SV-11 Physical schema (UPDM - MODAF aliases)
Creation
To create an SV-11 Physical Schema:
• Right-click the Physical Data Model that is to own the SV-11 Physical Schema, point to New, point to MODAF, point to System, and then click SV-11 Physical Schema.
Purpose
On an SV-11 Physical Schema:
• Create Resource Constraint elements and apply them to Exchange Element and Entity Item elements.
Diagram 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 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.
To create an Entity Item: click the 
Entity Item button, and then click in free space on the diagram. Use:
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 required 
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.
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.
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 Physical Data Model: click the 
Physical Data Model button, and then click in free space on the diagram.
Physical Data Model button, and then click in free space on the diagram.To populate elements from a Physical Data Model: add the Physical Data Model to the diagram, and then populate those elements from that Physical Data Model.
To create a Resource Constraint: click the 
Resource Constraint button, and then click in free space on the diagram. Use the Full Text property to specify the text of the Resource Constraint.
Resource Constraint button, and then click in free space on the diagram. Use the Full Text property to specify the text of the Resource Constraint.To apply a Resource Constraint to an Entity Item and Exchange Element on the diagram: click the 
Note Link button, click the Resource Constraint, and then click the Entity Item or Exchange Element to which the Resource Constraint applies.
Note Link button, click the Resource Constraint, and then click the Entity Item or Exchange Element to which the Resource Constraint applies.The following sections provide information about how an SV-11 Physical Schema is used in the model.
