Figure 34 Association Specification--Detail Tab

Refer to the descriptions in the Introduction to Specifications chapter for information on the specification elements not covered in the following section.

Derived

This field indicates whether the element was computed (derived) or implemented directly.

To define an element as derived, select the Derived check box. The element name is adorned by a "/" in front of the name.

Link Element

This field lists the attributed associations linked to the association. These attributed associations apply to the association as a whole.

Name Direction

This field defines the direction of an association name.

Constraints

The constraint is an expression of some semantic condition that must be preserved while the system is in a steady state. The constraint on the Detail tab applies to the association as a whole, while the constraint on the Detail A or Detail B tab applies to a particular role.

To apply a constraint, click the Constraint field and enter the text. A constraint is displayed notationally, surrounded by braces under the role to which it applies.
