摘要
在分析Web环境下传统联机分析处理(online analytical processing OLAP)系统存在问题的基础上,提出一种基于对象池和数据缓存技术的OLAP系统的体系结构.首先给出了对象池的定义及处理用户请求的算法,然后给出了数据缓存的定义及数据缓存的处理算法.采用对象池及数据缓存技术相结合,可明显提高系统的性能.
By analyzing the existing problems of traditional OLAP systematic in a OLAP system based on object pool and data caching is proposed. The definition web environment, a system structure of of data pool is given, and a processing processing algorithm are given. Object pool holds certain quantity of objects. An object is a function unit capable of providing decision support, which visits data in the data cache. If the data does not exist, it turns to the OLAP server so that the system performance can be greatly enhanced, and the OLAP server＇s burden is lessened. Finally, system implementation and application results are discussed.
