CI relationships in the CMDB

The CMDB, in contrast to a static asset list, helps you track not only the configuration items (CIs) within your system, but also the relationships between those items.

A relationship in the CMDB consists of two CIs and a relationship type:

  • Parent CI
  • Child CI
  • Type of the relationship that links both CIs

For example, in the [Server1] [Managed by] [Server2] relationship:

  • Server1 is the child CI
  • Server2 is the parent CI
  • [Managed by] is the relationship type

For example, a web application might read data from a particular instance of Oracle, which in turn might depend on a piece of underlying hardware. Most CIs in a CMDB have multiple relationships to other CIs, users, and groups.

The relationships between CIs can be automatically discovered. If you use Discovery, many relationships can be automatically loaded into the system through the discovery process. If you import your data from another system, you may get some form of relationships.

You can add to automatically discovered relationships, create new relationships, or edit relationships for a CI by launching the CI relationship editor from the CI form.
