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 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.
