摘要
阐述了利用数据仓库的聚合技术 ,通过设计不同粒度的分级表 ,实现了对网络流量的海量数据的高效处理 .给出了流量分析数据库的设计思想及结构描述 ,讨论了数据聚合过程 .通过采用梯形式的聚合方式 ,在保证有用信息粒度的基础上 ,可以大大减少数据量和存储空间 ,提高查询效率 .
How to efficiently process the huge data by using technique of dataware convergence and hierarchical-tables with different granularities was presented. The design of database of traffic data was analyzed and the structure of database was described. The process of converging the data was also discussed. In this way, the data's bulk and storage space is cut down and the efficiency of query is improved while the resolution of information is guaranteed.
