Recently, many services regarding moving object have been studied with using location information as mobile devices and systems are advancing. Trajectory is the data which information of the location by the time. The current database system is not defined that to store of the moving object data type. Therefore, the location information of object can be stored, but it is difficult to store those location information and time information together.
