摘要 对时空数据库中移动对象进行有效存取、查询和更新的关键技术在于索引。深入分析了移动对象轨迹限制索引和非限制索引中的各种索引技术,最后讨论了移动对象索引技术研究中的问题并对未来方向进行了展望。 To efficiently store, query and update trajectories of moving objects in spatio-temporal database, indexing techniques are sticking points. This paper thoroughly analyzed indexing methods for constrained and nonconstrained trajectory, and finally some open researching problems and interesting direction were presented.
