摘要

我们将提出一个四维轨迹模型，用于捕捉运动物体的动态位置。基于该模型，我们将介绍查询操作符的用法，并在ORDBMS上实现这些查询，并研究索引对这些移动对象查询性能的影响。最后，通过实验验证了该方法的有效性。

Performance assessment of retrieving information of moving objects with spatio-temporal index

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.
