De-Duplication of Configuration Items Related to a Managed Network

A system may include a database containing representations of configuration items associated with a managed network that is managed by a remote network management platform. The system may also contain a server device that may be configured to determine a set of duplicate representations of a particular configuration item of the configuration items. The configuration items may relate to computing devices and software applications disposed within the managed network. The server device may be further configured to generate a master representation from the set of duplicate configuration items. The server device may replace, in the database, the set of duplicate representations with the master representation.
