Configuration Management Database (CMDB) is a centralized repository that stores information on all the significant entities of your IT environment. The entities, termed as Configuration Items (CIs) constitutes of Hardware, the installed Software Applications, Documents, Business Services and People that are part of your IT system. Unlike the asset database that comprises of a bunch of CIs, the CMDB is designed to support a vast IT structure where the interrelation between the CIs are maintained and supported successfully.
Each CI within the CMDB is represented with Attributes and Relationships. Attributes are data elements that describe the characteristics of CIs under a CI Type. For instance, the attributes for CI Type Server would be Model, Service Tag, Processor Name and so on. Relationships denote the link between two CIs that identifies the dependency or connection between them.
CMDB functions as an effective decision making tool by playing a critical role in impact analysis and root cause determination. In the following documents, you will take a look at Configuring the CMDB configurations, Defining the CI Relationships and viewing the Relationship Map.
