  abstract = {Effective timed data processing belongs to one of the most important task of the development of current information and database systems. It is not, however, only the changes in time management, but also the complex record of
changes during the whole life cycle of the object – historical values, actual states, but also data valid in the future. Existing
temporal solutions are inadequate in terms of performance - effectiveness of the whole system, which is manifested by the size
of the required data and processing time. There is no temporal solution for Select statement defined and user has to manage
it explicitly. This paper deals with the principles of temporal data modelling on object and attribute level. It also describes the
characteristics of Select statement used in temporal system, extends it with new characteristics and defines new layer for
transformation into existing syntax.},
