数据库优化查询架构的设计与仿真

Database Query Optimization and Simulation Framework

针对当前数据库查询过程中,在处理海量数据的时候,使用的常规查询方法不仅浪费数据库资源,多次重复无用操作,而且可能使数据库负担过重而崩溃,使得查询数据库非常费时费力的问题.本文提出了构造XML文档来模拟数据库,将数据库的查询转化为对XML的查询.在使用上提出了一种更加便捷的查询解决的方案.仿真实验证明,该模型能够大幅提高数据的查询速度,取得很好的效果.

In view of the current database query process,in handling mass data,using conventional inquires the method not only waste the database resource,repeating the useless operations may make database burden and collapse,make inquires very time-consuming.This paper proposed to simulate an XML document database structure,database inquiry into an XML query.Using on proposed a more convenient inquires the solution.Computer simulation results proved that the query model can be vastly improved data query speed,and get a good effect.
