Research of Index Mechanisms in Spatio-temporal Databases
时空数据库索引机制研究

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.
