【摘要】 通过对多维数据库的分析,提出多维技术可以应用到面向学科的知识仓库中。以构建三维数据立方体结构电子期刊数据库模型为例,对数据立方体模型进行简单定义,分析切片、切块、钻取、旋转等各种多维操作动作。采用多种途径实现多维数据库的物理存储。更多还原

【Abstract】 Analyzing multidimensional database,the paper puts forward multidimensional technology which may be used in discipline-oriented knowledge warehouse.The paper takes example for constructing a tridimensional data cube structure model of electronic journals database,and simply defines data cube model,analyzes various multidimensional operation action,like slice,dice,drill-down and roll-up,and pivot.The paper realizes physical memory of multidimensional database by many ways.更多还原
