基于SQLite的战场态势信息快速存取研究

摘要

To meet the needs of soldiers for battlefield situation information who equipped with mobile terminal,a means of realtime query using little embedded database SQLite as the underlying storage is proposed.Firstly,a store model is put forward according to the manner of situation information's description.Next,hash table's idea is introduced to design the structure of tables.And then,extraction is adopted to realize real-time query.Finally,The experiment shows that the method runs effectively.%为满足使用移动终端设备的作战单元对于战场态势信息的实时查询需求,提出了一种以小型嵌入式数据库SQLite为底层存储的查询预处理方法.根据态势信息的描述方式建立了信息存储模型,在此基础上结合Hash表检索思想设计了表结构,进而采用抽取压缩的思想实现态势信息的快速查询,通过仿真分析表明了该方法具有较好的效果.
