摘要 基于关系数据库聚簇索引的逻辑和存储方式,提出在对象关系模型中遍历关联对象时缓存中间结果的连接算法,并给出了性能分析公式,通过计算和模拟实验证明了采用该方法查询关联对象时能减少磁盘的I/O次数和磁盘访问时间。 Based on the cluster index logical in relational DBMS, a join algorithm about the middle result of relational objects was presented and the performance analysis formula was given. The experimental result show that the algorithm can decrease the amount of the disk I/O access and the expense of disk access effectively when querying relational objects.
