A configuration managementdatabase
(CMDB) is a database in which the service desk applications are interlinked with the classic system management tasks and relationships are established between the business processes. It is not a database in the true sense of the word, but a kind of reference structure that acts as a data mediator within the Business Service Management (CMDB). Changes are entered into this reference structure and the user can see the relationships between the various components of a business process and their function and significance. The Configuration Management Database forms a core module for service management.
