Metoda wyceny wartości zbiorów danych na potrzeby zarządzania cyklem życia informacji
METHOD OF DATA SET VALUATION FOR INFORMATION LIFECYCLE MANAGEMENT

Summary/Abstract: Estimating the value of stored information is an important element of information lifecycle management, allowing to distribute stored data sets to the most appropriate storage subsystems, characterized by different levels of costs and performance. Because of the huge amounts of data kept in contemporary storage systems, this task has to be accomplished using methods which are simple and capable of being automated. The method proposed in this paper meets these requirements. It uses a value model based on only two easily measurable parameters: data set usage frequency, and the moment of time the usage took place. Compared to the existing methods of similar type, the proposed method is much simpler, both in preparation and use.
