چکیده
The paper presents the research of temporal data usage in the information systems (IS) for railway transport. In the research the IS artifact building phase has been executed. The models and methods oriented at the operation with the temporal objects of the railway transport system have been designed. The work takes into consideration the problems of the temporal objects presentation in the relational databases, as well as the problems of provision of their integrity and the questions of interaction with them. The investigation results have been employed in the development of the interactive passenger train schedule IS for the Latvian Railway.
