Spatial data service optimizing based on dynamic index and buffer pool
Xitong Fangzhen Xuebao / Journal of System Simulation(2008)
Abstract
Aiming at the performance advance of spatial data service, data accessing behavior and index scheme were researched. Based on the influence from human to data, a non-uniform data accessing conception, dynamic index and buffer pool basing on attention degree were put forward, and a double-index application pattern was designed. Emulational experiments with real data prove that the methods can improve the data indexing speed and total service performance efficiently.
