Intellectual Information Technologies in the Tasks of Perfection of the Hydrometeorological Systems

In spite of the large accumulated volume of information in hydrometeorological industry and also necessity of multidimensional analysis of these data, scientific work connected with the use of modern technologies of intellectual analysis for the increase of speed of analysis of hydrometeorological data was not conducted until now. The reason for it might be lack of any competition in this branch of science. The article deals with the technology of on-line analytical processing (OLAP) of the hydrometeorological data consisting in creation of a two-level subsystem of storage which is used for the first time. The article presents schemes of operational and analytical databases with the description of requirements to them, and also describes the modules providing synchronization of data between these databases. Possibility of creation of OLAP library of cubes on various measurements after the analysis of selections of the data necessary for employees of hydrometeorological branch for the analysis and forecasting is suggested.
