Which should be used to explore the entire hierarchy and table definitions of the Configuration Management Database Classes?

Application Menus are navigation configuration records used to organize modules in the left navigation bar, not a tool for exploring CMDB table hierarchies.

Reports are used to query and display data from tables but do not provide a structural view of the class hierarchy or table definitions.

CI Class Manager provides a graphical tree view of the entire CMDB class hierarchy, allowing administrators to browse parent-child table relationships, view and edit CI class attributes, manage identification rules, and review table definitions - all from a single unified interface purpose-built for CMDB schema exploration.

Dependency View displays relationships between specific CI instances (such as application dependencies), not the structural class hierarchy of the CMDB schema.
