From a data model perspective which Table is the base class for the configuration management database?

In the CMDB table hierarchy the physical table cmdb, whose label is “Base Configuration Item,” is the root (base) class. Every other CMDB class—including Configuration Item [cmdbci]—extends from this cmdb table. Therefore, from a data-model standpoint, Base Configuration Item (cmdb) is the foundational class for the configuration management database.

A. Base Item [cmdbbaseitem] – Not part of the CMDB hierarchy; unrelated table.

B. Configuration Item [cmdbci] – Child table that extends from the cmdb base, not the root.

D. Asset [asset] – Belongs to Asset Management; does not underlie CMDB classes.
