N2 - One of the crucial problems characterizing current data warehouses is the implicit assumption of dimension invariance with respect to the time dimension. This assumption inhibits the proper treatment of changes in dimension data. Meanwhile, we can give examples indicating that it is necessary to take into consideration the modifications of dimension data - ignoring such changes leads to incorrect analysis which then results in wrong decisions. This article describes the implemented temporal telemetric data warehouse system, which provides the user with the ability to query about the time interval embracing many structure versions. The system also informs the user about modifications which occurred in separated structure versions.
