摘　　要：大数据量查询经常出现系统响应时间过长、系统资源占用过多等一系列问题，是无人机侦察情报处理系统处理性能的瓶颈。系统采用了一系列查询优化技术：合理设计表结构、内存优化、索引技术、分区技术等，从而实现数据查询的高效性、稳定性。A set of problems which frequently arise in large amount of data query are that system response time is too long and many system resources are taken up, which are the bottleneck of processing performance of UAV reconnaissance and information processing system. A series of query optimization techniques including reasonable design for list structure, optimizing internal memory, indexing technique and partition technique are employed in the proposed system to achieve high efficiency and stability of data query.
