N-Ary Association
Description
An n-Ary Association element is used to model complex relationships between three or more elements, typically in a Class diagram. It is not a commonly-employed device, but can be used to good effect where there is a dependant relationship between several elements. It is generally used with the Association connector, but the relationships can include other types of connector.
In the example above there is a relationship between a Company, an Employee and a Salary.
