一种基于Flash DBMS的动态日志方法

Flash作为一种高密度新型的存储介质,具有读写速度快、抗震能力强、体积小、重量轻等很多优点,使用Flash芯片的SSD硬盘将代替传统磁盘,更广泛地应用在个人电脑以及服务器设备上。由此,在Flash平台上部署和运行数据库系统就成为我们必须思考和研究的问题。由于Flash与传统磁盘特性不同,不能简单地将基于传统磁盘的数据库系统应用在Flash平台上。提出一种动态日志的方法,更好地利用Flash介质本身的特性,提高基于Flash平台的DBMS性能。

A DYNAMIC LOGGING APPROACH FOR FLASH-BASED DBMS

Flash,as a novel storage medium with high density,has many advantages including high reading and writing speed,good vibration-resistance,light weight and small size,etc.,the SSD hard disk with Flash chips will supersede the conventional magnetic disks to be more extensively applied to personal computers and server devices.Therefore,the disposal and running of database system on Flash platforms is to be an issue that we have to ponder and study.However,disk-based database system can not be simply applied to ...
