A configuration management database (CMDB) is an ITIL term for a database used by an organization to store information about hardware and software assets (commonly referred to as configuration items). It is useful to break down configuration items into logical layers.^[1] This database acts as a data warehouse for the organization and also stores information regarding the relationships among its assets.^[2] The CMDB provides a means of understanding the organization's critical assets and their relationships, such as information systems, upstream sources or dependencies of assets, and the downstream targets of assets.^[3]
