- To create package relationships Click to select the Dependency icon on the toolbar. Click on the package playing the role of the client. Drag the dependency line to the package playing the role of the supplier.
- To create an association relationship Click to select the Unidirectional Association icon on the toolbar. Click on the class on the non-navigable end and drag the association line to the class on the navigable end. To create an aggregation relationship Click to select the Unidirectional Aggregation icon on the toolbar.

The CourseOffering can send messages to the Student and the Student can send messages to the CourseOffering. Explain that this is NOT a data flow. Data can flow in both directions (i.e.. A message may be answered). It is showing who directs the messages.

Explain that navigation is shown in the Browser. If an association is not navigable, then the role will be shown in the Browser but it will be grayed out. Explain this picture. The Professor has associations (or aggregations) to the CourseOffering class and the Department class. The Professor can navigate to the Department. The Professor CANNOT navigate to the CourseOffering. The CourseOffering has an association to the Professor. The CourseOffering can navigate to the Professor. STRESS that in Rose, associations and aggregations are owned by the package that owns the diagram used to create them. This means that if the classes involved in the relationship are relocated, the relationships should be relocated. This was hard to do before.
- To name an association Click to select the association line on a class diagram. While the line is still selected, enter its name. Note: You can also name aggregations but this is not typically done since they are read using the word “contains”. Associations and aggregations may be named.

In a reflexive relationship, multiple objects in the same class collaborate together. Read the model. One Course in the role of a pre-requisite is related to zero to many Courses One Course is related to zero to many Courses playing the role of a pre-requisite.
- To create a constraint that applies to the association in general Click right on the association or aggregation to make the pop up menu visible. Select the Open Specification menu command. Select the Detail tab. Enter the constraint in the Constraints field. Click the OK button to close the Specification.
