中文摘要: 本文以加快嵌入式数据库SQLite的数据查询速度为出发点，提出了一种在原有SQLite的B+树索引机制的基础上改进的新索引机制，在对嵌入式内存资源影响不大的前提下提高了SQLite的查询速度.
Abstract:In order to accelerate the query speed of embedded database SQLite, we propose an improved index mechanism based on the original B+ tree, which can actually improve the query speed with little influence on the embedded memory resources.
