Relationships

Relationships are used to show the relationships between objects and consist of associations and composition.

Note: The terms described in this section are identical in meaning to the same terms described in UML.

Relationships in the business object model can be grouped into two types:

  • Associations, and Composition. Composition is a more specific type of the general relationship type Association.

    These types can be further classified with regards to:

    • End ownership (Composition only).
    • Navigability. These relationships may be unidirectional or bidirectional.

All relationships can have various labels when they are created in a business object model. A label name for the relationship is not displayed by default but can be added. They also display the names of the Classes and the multiplicity allowed for the Classes.

This is shown below:

Tip: You can choose to hide these labels by clicking or you can delete the ones that you do not require from the actual Model. If you delete them from the Model, you are not actually deleting the labels, you are hiding them. You can display them again by clicking .
