Embodiment

[0041] Example: such as figure 1 As shown, a data cube-oriented operable graphical pivot table construction method, according to the needs of the application scenario, set the known data source, select the corresponding dimension and measure to complete a data cube, according to the information of the data cube, in the data perspective Perform OLAP operations on the table, where the pivot table such as figure 2 shown, including the following steps:

[0042] 1) for image 3 In the configuration file of the data cube, the dimension of the data cube and the definition configuration information of the measurement are obtained in the configuration file. where the cube model such as Figure 4 shown.

[0043] 2) Query the level of each dimension, and query the dimension members of different levels in the dimension level, and construct a B+ tree, according to image 3 The schematic diagram of the data cube dimension member B+ tree in Figure 5 shown;

[0044] 3) According to ...

Abstract

The invention relates to a data cube-oriented operable graphic perspective table construction method, which comprises the following steps of: projecting a cube into a two-dimensional data perspectivetable, and quickly indexing member information of dimensions by adopting a B + tree according to the dimensions and measurement information displayed by horizontal and longitudinal axes of the perspective table configured by a user, and in combination with a table algebra calculation table structure and a table header structure, obtaining a row and column structure of a table data area and a numerical attribute of each data unit, and constructing an MDX query statement according to the calculated attributes to query a corresponding specific numerical value in the data cube. When the user operates the level of the dimension hierarchy, the user only needs to combine the B + tree of the dimension and the table algebra again to quickly calculate the table structure and index the data. The inventionadapts to the characteristics of simplicity and intuition of a data perspective table, has the characteristics of agile perspective table operation response, efficient processing of a large amount of data and the like, and can quickly calculate and reduce system I / O.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method for constructing an operable graphic pivot table oriented to a data cube. Background technique [0002] In recent years, enterprises have accumulated more and more data in the development of the Internet era. As the granularity of data becomes finer and the number of Internet users increases, the magnitude of these data shows an exponential growth trend. Although the price of storage is declining day by day, how to use these massive data to extract valuable information from the data, dig out the meaning and relevance behind the data, promote the value of the data, and convert the data into intuitive graphical reports, which is convenient for enterprise managers Analyzing data, and then promoting the formulation of corporate decisions, planning the development direction of the enterprise, and enhancing the competitiveness of the enterprise in the market, these hav...
