The variable could be as simple as an integer or a string or as complex as a multidimensional array or an object.
变量可以像一个整数或字符串那样简单，也可以像多维数组或对象那样复杂。
To treat every dimension equally and adapt to sparse data, it is necessary to partition multidimensional array.
为了等同的对待每个维，适应稀疏数据，必须对多维数组进行划分。
The following example illustrates the difference between defined a one-dimensional array and a multidimensional array.
下面的示例阐释了定义一维数组和多维数组之间的区别。
When you add dimensions to an array, the total storage needed by the array increases considerably, so use multidimensional arrays with care.
增加一个数组的维数时，该数组所需的总存储空间会急剧增大，因此应慎用多维数组。
Calling the function in Listing 2 from the reporting application creates a multidimensional array—some sample values are $ccaarr[2][0]=2005 and $ccaarr[2][6]=0.1.
从报表应用程序调用清单2中的函数会创建一个多维数组 —一些样例值是 $ccaarr[2][0]=2005和 $ccaarr[2][6]=0.1。
Since data cubes are such a useful interpretation tool, most OLAP products are built around a structure in which the cube is modeled as a multidimensional array.
由于数据立方体是一个非常有用的解释工具，所以大多数OLAP产品都围绕着按多维阵列建立立方模型这样一个结构编制。
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。
