About attribute inheritance

When creating a classification structure, administrators assign attributes to the different classes in the hierarchy. These attributes describe each class and all subclasses of that class. Each subclass inherits all the attributes that are contained in the parent class. Setting up the attributes in this way makes searching more effective. You can select a top class and search for a tool within that class using a particular value knowing that that attribute is also contained in all the child classes of the class. In the figure below, you can see that only Attribute E is assigned to the Twist Drills class. All other attributes are inherited from the parent classes.
