Configuration management database
open-in-new
<p>A configuration management database (CMDB) is an <a href="/facts/ITIL/1Rnl4DUl">ITIL</a> term for a <a href="/facts/Database/VYcpkevb">database</a> used by an organization to store information about hardware and software assets (commonly referred to as <a href="/facts/Configuration_item/WjhbgbSK">configuration items</a>). It is useful to break down configuration items into logical layers. This database acts as a <a href="/facts/Data_warehouse/we5rblq9">data warehouse</a> for the organization and also stores information regarding the relationships among its assets. The CMDB provides a means of understanding the organization's critical assets and their relationships, such as <a href="/facts/Information_system/apcSzFLh">information systems</a>, upstream sources or dependencies of assets, and the downstream targets of assets. </p>
