Huang Shu · Journal of Suzhou Institute of Silk Textile Technology · 2002
More and more database systems store and manage spatio-temporal objects that change positions and/or extents over time, index mechanisms are key technologies in spatio-temporal database system in supporting efficient spatio-temporal access methods. The paper analyzes the features of the spatio-temporal objects in discrete environment, studies a set of fundamental query types that the index mechanisms should support, and discusses the key technologies of spatio-temporal indexes in discrete environment.
