Application of On-Line Analytical Processing systems in monitoring of electrical power engineering devices

The paper presents the idea of using and application of On-Line Analytical Processing (OLAP) systems in monitoring of electrical power engineering devices. Data saved in central repository for historical data are submitted through online working analytic systems. At the moment of addition of new data happens process of definition the mutual correlation between the new and already existing data. This leads to the analysis based on OLAP systems. The hereby paper describes the advantages of OLAP systems in aspect of using them in monitoring of electrical power engineering devices.
