CMDB

CMDB stands for Configuration Management DataBase

''The CMDB is a repository that acts as a data warehouse for information technology (IT) organizations. Its contents is intended to hold a collection of IT assets that are commonly referred to as Configuration Items (CIs), as well as descriptive relationships between such assets. When populated, the repository becomes a means of understanding how critical assets such as information systems are composed, what their upstream sources or dependencies are, and what their downstream targets are.''
