摘要
文中从基于国产DBMS-DM3的MDM3体系入手,在分析了当前各种替换策略优缺点的基础上,提出了语义簇的概念及结构,给出了适合MDM3的缓存物理存储结构及缓存替换策略,最后给出了详细的替换算法。
Firstly, based on introducing the structure of MDM3 and analyzing representative cache replacement polices, this paper gives the concept of semantic cluster and produces its structure. Then, it gives the proper physical storage structure for MDM3 and replacement policy. At last it presents the semantic cache replacement algorithm in detail.
