Abstract(in English)	The recent progress on positioning systems such as GPS (Geographical Positioning System) or motion capturing systems are tremendous, which leads to the users' request to store and use of moving objects in databases. However, in most cases only position data are stored in the database, which are not sufficient to perform various types of complex queries and simulation. In order to improve this problem, we propose a new spatio-temporal data model which can represent not only the position of a moving object but also its orientation, slope and figure by introducing the local coordinate system in addition to the global coordinate system.
