They suggest that a large number of people in a single mega-cube (or some other open workspace) would be chaotic.
他们认为一大群人在一个大空间(或一些其它开放式工作区)的地方会很混乱。
As the number of dimensions increases, the cube becomes sparser-that is, many cells representing specific attribute combinations are empty, containing no aggregated data.
随着维度数目的增加,立方体变得更稀疏,即表示某些属性组合的多个单元是空的,没有集合的数据。
The ROLAP data cube is implemented as a collection of relational tables (up to twice as many as the number of dimensions) instead of as a multidimensional array.
ROLAP数据立方体是按关系表格的集合实现的(最多可达维度数目的两倍),来代替多维阵列。
