What is the configuration management database?

Configuration management database (CMDB) is one or more databases used as a means for information technology managers (IT) to plan and organize all aspects of the IT environment of the organization. Almost everything that includes the IT functioning of the organization can go to CMDB, where each entry into the database becomes the so -called configuration item (CI). This includes not only computer hardware and software inventory and control, but also operation methods, specific incidents and changes in IT environments, even people.

The content of a particular CMDB may vary according to a department or service. CIS for the organization are collected to CMDB, which becomes a central information storage for their monitoring and their relationships with each other. With a good implementation of CMDB, the organization can make a more informed decision on IT planning, management and necessary expenditure for IT infrastructure maintenance.

The idea of ​​him to manage configuration was created from the functioning of central computer and telecommunicationsH agencies, which eventually became the Office of Government Trade, Government Agency in the UK (Great Britain). The group maintains and publishes a number of books that describe what is called the Information Technology Library (ITIL®). Part ITIL® included the recommended use of databases for managing IT environment and how they are configured.

When ITIL® continued to gain popularity outside government agencies and contracts in the UK, but the concept of configuration database has become somewhat confusing and a little controversy has appeared. Numerous companies raced to create real database applications that were launched as the only source to simplify IT department management. At a time when version three of Thobil was apparent, the idea for CMDB dropped under the section that described the more general configuration system (CMS) to better describe the idea of ​​using CMDB. Within the new oBjasnim can contain CMS one or more CMDB.

6 by approaching CMDB as a multiple database federation, using the notion of CMS described in the new ITIL®, the concept suggests any number of databases called data management storage (MDR), and resources communicating and share configuration items. The DMTF® standard helps companies that want to continue to develop databases for use as MDRS to do so in a way that will work with the MDR created by others.

In essence, at the top of the hierarchy, the primary configurationaedatabase of URATION, which can be considered something like a meta-database. It does not have to contain all details concerning a specific IT environment, instead it allows other trusted resources to maintain this information. Different CMDB organizations then share key data up to the primary CMDB, which is then used for general decision -making. The CMDB separation in this way allows better clarification and easier checking information about the cellIT environment.
