Embodiment 1
[0045] The specific implementation can be divided into two steps: the first is to build a multi-dimensional data cube; the second is to extract data from the multi-dimensional data cube and perform roll-up calculation. The details are now as follows:
[0046] The first step is to build a multidimensional data cube:
[0047] 1. Establish a blank basic table as the index table of the multidimensional data cube; the index table is composed of the following three columns: the column used to record the attribute type of the multidimensional data cube node, the column used to record the attribute value of the multidimensional data cube node , and a column for recording the index value of the multidimensional data cube node;
[0048] 2. Determine the index generation method. Here, the index value is implemented as an integer type or a real type, and the attribute value is implemented as a string type; firstly, an index value generation function GetIndexCode is established, and the ...
