A Basic Type is a data type that can be assigned to an Attribute, Operation, Parameter or Type Definition.

Create a Basic Type through a Modeler explorer pane or a Class Diagram:

• In a Modeler pane, right-click a Package, and select New > UML > Structure > Basic Type.

• On a Class Diagram tab, click the Basic Type button, and then click in free space.

When used on a Class Diagram, a Basic Type's notation is as follows:

For information about the View Options available for this symbol, see Basic type view options - class diagram.

Before deleting a Basic Type, ensure that you click the Details button from the confirmation dialog so that you can see which items reference that Basic Type.

In the Modeler panes, a short-cut symbol

on the Basic Type's icon indicates that the item is a stub. For more information, see Stubs.

The following sections provide information about how a Basic Type is used in the model. For more information about a property, item, model part or diagram, click it.
