Rami,
The benefits of an Class/Subclass data model include enforcement of common
attributes among similar types of CIs and the ability to search within not just
a given class of CIs, but within any branch of the hierarchy. From a base class
from which all others are derived, you can search for all CIs or all
relationships.
So an example of this would be a Switch and its components. A Switch is made
up of a 1 Chassis, multiple Controllers (Soup Engs), Multiple Power Supplies,
and Multiple Cards. Building Parent/Child relationships allows you to track the
individual components like a card or power supply by serial number/asset tag.
If a card needs to be replaced you remove the relationship and add the new card
and build the relationship. The old card can be sent in for repair and tracked.
When repaired, this card can be used in any switch that needs it.
I hope this answers your question.
