Performance Assessment of Retrieving Information of Moving Objects with Spatio-Temporal Index

摘要：

In this paper, we will present a 4 dimensional trajectory model for capturing dynamic locations of moving objects is proposed. Based upon this model, we will present a usage of query operators and implement these queries on ORDBMS and study the effect of indices on the performance of these moving object queries. Finally,the effectiveness of our approach is justified by some experiments.
