In contrast , when ext3 in " data ordered " mode , the default flushes data to the drive , it can result in a lot of additional seeks and , depending on the io load , even some unnecessary disk thrashing 相反,在ext3 ( “ data = ordered ”缺省方式)下,将数据清仓到磁盘时,将导致许多额外寻道,甚至还会引起某种不必要的磁盘抖动( thrashing ) (取决于io负载) 。
We independently develop the specialized information analysisdatabase , gathers the world newest competition tendency every day , performs the data ordering and the scientific analysis , provides hasthe value for the user the information 我们自主开发的专业资讯分析数据库,每日采集世界最新比赛动态,加以数据整理和科学分析,为用户提供具有价值的资讯。
However , existing algorithms is still sensitive to data order . high effective , self - adaptive , interactively dynamic , incremental clustering algorithm should be studied . clustering technique in data mining will yet be faced with many problems and challenges 目前的增量算法尚未完全解决对数据顺序的敏感性,高效、自适应性和交互性地动态地增量式聚类算法有待进一步研究,数据挖掘中的聚类技术仍面临着许多问题和挑战。
