Embodiment Construction

[0032] like figure 1 , figure 2 and image 3 As shown, the method for dynamically expanding the multi-dimensional data analysis model provided in this embodiment includes:

[0033] Step S10, importing a data set, and detecting the data set to obtain detection information. In this embodiment, the detection information of the data set is obtained by means of sampling detection, and the amount of sampling can be set as a percentage of the amount of data or in other ways. The method of sampling detection can greatly improve the detection speed of the data set. However, the present invention does not impose any limitation on the detection method. In other embodiments, the detection information of the data set may be obtained by means of full-sample detection.

[0034] In this embodiment, the detection information formed after the data set is detected includes data type, data content and data range, and the detection includes dimension extraction and data range calculation. T...

Abstract

The present invention provides a dynamic extension method and system for a multidimensional data analysis model. The extension method comprises: importing a data set, and detecting the data set to obtain detection information; mapping attribute fields in the data set to a preset dimensional model according to the detection information or establishing new dimensions to form a dimensional model obtained after dynamic extension; and establishing an element table representing a relationship between the attribute fields and elements corresponding to the attribute fields, and a relation table representing the relationship between the attribute fields and the internal levels of the attribute fields in the dimensional model according to the dimensional model obtained after dynamic extension. According to the dynamic extension method and system for a multidimensional data analysis model provided by the present invention, the dynamic extension of dimensions is supported, the extension is very flexible, the extensions among different users cannot cause mutual interference, the extension cost is very low, and dynamic and various data can be processed, so that the dynamic extension method and system conform to the demands of the big data era.

Description

technical field [0001] The invention relates to the field of data analysis, and in particular relates to a method and system for dynamically expanding a multi-dimensional data analysis model. Background technique [0002] The data analysis system needs to express the business scenario it represents into a form that can be processed by the computer, which is the data model for analysis. At the same time, users also use the data model to understand the data and interact with the system. [0003] At present, there are two main methods to implement data analysis: one is to customize an application for a certain scene, which can describe the analysis object more appropriately, and theoretically can achieve the desired effect, but the development resource requirements are high, and the level of developers is greatly restricted. . [0004] Another approach is to build languages ​​or tools that can describe different data models in an analysis system. This method makes the data a...
