摘要: 针对嵌入式数据库中B+_树索引机制的空间利用率低下及面对庞杂数据的处理能力不足,提出了一种改进的B+_树索引机制,使用这种索引机制能较好地解决在存储容量受限的嵌入式系统中提高数据空间利用率和处理庞杂数据能力的问题。

Abstract: This paper is due to B+_trees shorting of low storage utilization and its weak processing ability of mass data in embedded database, presents an improved B+_trees method to guarantee high storage utilization and its strong processing ability of mass data in limited storage embedded system.

Key words: embedded database, index method, improved B+_trees method
