The underlying data model allows for the consistent structuring of all data; using normalization, the information coming from a wide variety of different devices and systems can be easily compared. From a technical point of view, configuration items describe the properties of Managed Objects and their mutual interrelations. Configuration management (CM) cannot be equated with asset or inventory management.
Baseline and change history
A "baseline" is a precisely specified status at a defined point in time (snapshot of the current situation) that is managed as part of the Configuration Management. This baseline is where the CMDB and the information from the other ITIL processes are based. Using theGuard! Configuration Management one can specify target configurations on the basis of configuration items and compare them to the current status. Deviations, which could also cause problems, can thus be quickly and reliably detected. If required, a change history can be logged on the configuration items.
