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 Entity Item, Entity Attribute, Exchange Element and Physical Data Model elements.
• Create Entity Relationship and Details relationships.
• Create Resource 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:
• Setting up default view options and compartments for a product diagram (UPDM)
• Setting up default view options and compartments for new product diagrams (UPDM)
• Working with compartments on symbols and linked callout notes (UPDM)
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), click here .
Details
To create a Details: click the Details toolbar button, click the source Entity Item, and then click the destination Exchange Element.
Entity Attribute
To create an Entity Attribute: click the
Entity Attribute toolbar 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 toolbar 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.
Entity Relationship
To create an Entity Relationship: click the required Entity Relationship toolbar button, click the source Entity Item, and then click the destination Entity Item.
Exchange Element
To create an Exchange Element: click the Exchange Element toolbar 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 toolbar 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.
Physical Data Model
To create a Physical Data Model: click the Physical Data Model toolbar 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.
Resource Constraint
To create a Resource Constraint: click the Resource Constraint toolbar 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 toolbar 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.
