View and edit class definitions and metadata

Use the CI Class Manager as a central location to explore the CMDB class hierarchy, CI table definitions, and class CIs. View the details of each table such as its label and fields, relationships, and all related metadata definitions.

About this task

The CI Class Manager displays the entire CMDB class hierarchy in a tree-view format, consolidating class definitions into a central location. It lets you display metadata information for a class, such as reconciliation rules, mandatory and recommended fields, and audit templates. You can also select a specific class to view, to modify, or to extend its definition to create a derived class. For each table, you can directly access CMDB Health settings and rules such as datasource precedence rules, orphan scorecard, and certificate template defined for the table class.

For more information about extending a class and how attributes are derived from a parent class in that process, see Table extension and classes.
