| 摘 要： | Spatio-temporal database manages the large amount of spatial objects that change over time.It is necessary to query the spatio-temporal objects of the past and the current and to anticipate the future of spatio-temporal objects.It is important to design an efficient index mechanism for accessing the spatio-temporal data efficiently.The paper analyzes the features of the spatio-temporal objects,studies the methods of spatio-temporal index mechanisms,classifies the index mechanisms,and discusses the key technologies of spatio-temporal indexes.And it also presents the index methods of STADBS that we are studying.

| Abstract: | Spatio-temporal database manages the large amount of spatial objects that change over time. It is necessary to query the spatio-temporal objects of the past and the current and to anticipate the future of spatio-temporal object-s. It is important to design an efficient index mechanism for accessing the spatio-temporal data efficiently.The paper analyzes the features of the spatio-temporal objects , studies the methods of spatio-temporal index mechanisms , classifies the index mechanisms, and discusses the key technologies of spatio-temporal indexes. And it also presents the index methods of STADBS that we are studying. |
