The development of information technique requires that a data storage device must possess the character of ultra-high density, ultra-fast transfer rate and longer storage lifetime. At present, the storage density of the conventional optical data storage is reaching its physics limit. 信息技术的发展要求存储器件必须具备超高存储密度、超快存取速率以及长的存储寿命,而传统的数字光存储的存储密度已经接近其物理极限。
Based on introduce of definition and character of data storage, technology of implement is put forward by an easy use of file catalog structure in widely used database exploder software ( Visual Foxpro). 通过对数据仓库的定义、特征的介绍,结合现今广泛使用的VISUALFOXPRO数据库开发软件,提出了方便有效的采用文件目录结构方式来实现数据仓库的相关技术。
