度量维度(measures group)

        在数据方中的一些概念如维度(Dimension),度量(Measure),度量组(measure group),层次(hierarchy),级别(level)是很容易理解的,有个概念 度量维度(measures group)让人理解起来非常困难。
        MSDN的解释如下，"A measures dimension is the dimension that contains all of the measures in a cube. A measures dimension is a special type of dimension in which the members are typically aggregated (generally by sum or by count) based on the current member of each dimension attribute with which a specified measure exists"
        仔细研究以后发现，其实此处的度量维度就是指所有的度量，换句话说度量被当成了一种特殊的维度，这个维度如果有层次结构的话，他的层次结构也只能有一个级别,只所以混淆是因为它也是一种维度,不过是特殊的维度。
