   Display Length

   Definitions and Comment Display Length

   Relationship Display

   Relationship Line Orientation

   Orthogonal

   Specifies whether or not to display relationships with orthogonal lines which lay at right angles. Traditionally, orthogonal lines are used in the diagram window for logical and physical models.

   Diagonal

   Specifies whether or not to display relationships with diagonal lines. Traditionally, diagonal lines are used for star schema diagrams in a dimensional model.

   Display Dangling Relationships

   Specifies whether or not to show dangling relationship lines in the diagram. Select the check box to display dangling relationship lines, or clear the check box to hide dangling relationship lines.

   Split Verb Phrase

   Splits the parent-to-child and child-to-parent verb phrases on each relationship line.

   Display Subcategory Cardinality

   Display the cardinality symbol for relationship lines in a supertype/subtype construct.

   Note: For the Display Subcategory Cardinality option to work, you must select Display Logical Relationship Name on the Relationship tab.

   Display Lines on Top

   When a relationship line passes through an object, displays the relationship line on top the object. If you clear the check box, displays the relationship line behind the object which it is passing through.
