Managing relationships between configuration items
Configuration items (CIs) do not exist in a vacuum; CIs affect each other. For example, one CI could use, depend on, be a component of, enable, be a member of, or be located in another CI. Storing these relationships in the CMDB enables you to see how CIs interrelate and affect one another.
The use of relationships is a feature that differentiates between a CMDB and an asset store.
Relationships can be simple, such as a disk drive being a component of a computer system, or more complex. Relationships exist not only between physical CIs, but also between logical and conceptual CIs, such as the software instances and service instance. Relationship data makes the CMDB a powerful decision support tool. Understanding the dependencies and other relationships among your CIs can tell you how upgrading Processor A can improve Server B's performance or which services are affected if Router C failed. Most downtime is caused by issues stemming from configuration changes. Accurate relationship information can help you prevent those issues.
If you do not have the Create, Edit, and Delete permissions on the class of a CI, the New and Save toolbar buttons are disabled.
The following topics are provided:

- Click the Remedyforce CMDB tab.

To search for a CI, type initial characters of the name of the CI or the full name of the class name in the Search text box and click For example, to search for Email Service CI, you can type Email or Email Service in the Search text box and click . You can also search using data in the Instance ID, Instance Name, Description, Class Name, Asset #, Token ID, and Serial # fields.
