## Summary of CMDB CI Class Models

The CMDB CI Class Models ServiceNow® Store app enhances the Configuration Management Database (CMDB) by adding extended class models to the existing CMDB class hierarchy.
These extensions include detailed class descriptions, identification rules, identifier entries, and dependent relationships where applicable.
The added classes function like native CMDB classes and enable applications such as Discovery and Service Mapping to better populate and discover configuration items (CIs) related to various technologies and software.

## Key Features

* **Extended CMDB Classes:** Adds new classes, columns, and metadata stored in tables including CMDB Class Information, Identifier, Identifier Entry, and CMDB Metadata Hosting Rules.
* **Discovery Support:** Supports discovery of specific technologies and software by leveraging extension classes, improving accuracy and completeness of CI data.
* **Technology Coverage:** Provides extension classes for technologies such as Avi load balancers, Oracle RDS, Firewalls, IBM Hardware Management Console, IoT, Nutanix, OpenStack, Red Hat Virtualization, Transport Layer Security, VMware NSX, and more.
* **Integration with Discovery Patterns:** Works alongside related Discovery patterns and Service Graph Connectors to streamline data import and integration from third-party sources.

## Practical Use and Verification

After installing the CMDB CI Class Models app, verify successful installation by navigating to **All \> Configuration \> CI Class Manager** in ServiceNow. Use the Hierarchy view to see the list of added classes and review their details, identification rules, and dependent relationships. This ensures that the extended classes are properly integrated into the CMDB structure.

## Important Considerations

Uninstalling this app may compromise CMDB integrity and lead to unexpected behavior, so it should be done with caution.  
The CMDB contains base-system classes that store data about configuration items (CIs). The CMDB CI Class Models
ServiceNow® Store app adds class models that extend the CMDB class hierarchy, including class descriptions, identification rules, identifier entries, and dependent relationships if applicable.
You can use the added classes like any other class. Applications such as Discovery and Service Mapping can use class extensions to populate CIs and to discover technologies and software.

See the CMDB CI Class Models release notes.

## Add class models {#cmdb-ci-class-models__section_czx_srb_qhb}

The app adds classes, columns, and associated metadata as related records in the following tables:

* CMDB Class Information \[cmdb_class_info\]: Class descriptions
* Identifier \[cmdb_identifier\]: Identification rules
* Identifier Entry \[cmdb_identifier_entry\]: Identification entries
* CMDB Metadata Hosting Rules \[cmdb_metadata_hosting\]: Dependent relationships
