Click on Composition link provided in menu bar and drag a field from one table to another will create a composition relationship.

On right click popup menu, the option “Sub-Class” creates a new table which is a subclass of the existing one. It represents the sub-class relationship with a line and triangle pointing to the base or parent class.
