A new approach to the creation and use of databases (DB) in information processing systems based on the display of time series is considered. Status and trends of information support development in data processing systems are analyzed. The problems of using the database for applications characterized by the direct use of the time factor are considered. Based on the analysis of the display of the time factor, an approach to dynamic structuring of data in the database is proposed, based on the storage of not the information objects themselves, but the tendency of their progression in time. Theoretical and applied (algorithmic, software, linguistic) aspects of development and functioning of dynamic databases (DBD) are described. Technological features of DBD creation and use are considered, including operations of concentration, duplication and recovery of information. Possible methods of DBD creation are analyzed, spline approximation is adopted as the basic method. The concept of predicted databases is introduced, their creation on the basis of DBD is proposed, the reliability of information presentation and errors arising when using predicted databases are analyzed. The prerequisites for the use of DBD in automated information processing and control systems are given. Statistical issues of dynamic display of time series are considered.
