Defining CI Relationships
CI Relationships form a major part of your CMDB, as it is the relationships between the CIs that differentiate the CMDB from the asset database. A CMDB without relationships constitutes a bunch of CIs in a single database, fetched through scan or import process, or by manual addition. But with relationships, the users accessing CMDB can understand the interdependencies between the CIs, and in the case of a failure, the impact caused on another CI can be identified.
NOTE: To make your CMDB structure less complex, consider the relationships you will require in your CMDB and ensure to use the right relationship type to define the nature of relationship.
In order to define the CI relationships in your CMDB, three piece of information is required.
The CI for which the relationship is created
The Type of Relationship denoting the interdependencies between the CIs, and
The dependent CI.
Say, for instance, consider a sentence like "AssetExplorerServer Depends on CentOS2Server". Here, AssetExplorerServer is the CI for which the relationship is created, Depends on denotes the nature of relationship, and CentOS2Server forms the dependent CI.
Every CI in ManageEngine AssetExplorer is represented with Attributes and Relationship. While the Attributes are data elements describing the CIs, the relationships help in understanding the interdependencies between the CIs. The relationships can be defined from the relationship tab.

Click CMBD tab in the header pane.

If you would like to create relationships with other CIs, enable Search other CIs to Create Relationships radio button.
By default, the CIs available in the CMDB are listed in the Available CI(s) column. If the CI list is excessive in length, then you can conduct a search for the CI by entering the search string. Click Search button. The search result is displayed in the Available CI(s) column.
You can also view CIs under a specific CI Type. Select the CI Type from the drop-down, say, Department. The CIs available for the CI Type Department are listed under Available CI(s) column. You can also conduct a search operation if the CI list under a CI Type is excessive in length. Say, for the CI Type Department, the entered search string is "Finance". On clicking Search button, "Finance" appears in the Available CI(s) column.
Select the CI(s) from the Available CI(s) column. Click Move Right >> button to move the selected CI(s) to the Selected CI(s) column.
Select the nature of relationship between the CIs from Choose Relationship Type drop down.
