System and method for automatically creating calculation formula

Abstract

The invention relates to a system for automatically creating a calculation formula. The system comprises a calculation factor storage unit, an expression formula storage unit, an expression formula weight storage unit and a calculation formula creation unit, wherein the calculation factor storage unit is used for storing calculation factor data which influences values of all service objects; the expression formula storage unit is used for storing a plurality of expression formulas; each expression formula comprises operation amount and operators; the operation amount comprises the calculation factor data; the expression formula weight storage unit is used for storing weight data corresponding to each expression formula; the calculation formula creation unit is used for generating the calculation formula for calculating the values of the service objects according to the expression formulas and the corresponding weight data; and the calculation formula is the quotient of the weighted sum and the weight sum of the expression formulas. The invention also provides a corresponding method. In the system and the method, the calculation formula can be automatically created through the expression formulas and the corresponding weight data, and different calculation formulas can be created without independent encoding.

Description

technical field [0001] The present invention relates to the field of computer data processing, and more specifically, the present invention relates to a system and method for automatically creating calculation formulas. Background technique [0002] At present, different formulas are usually used to implement different data transformations, that is, the formulas need to be changed as the data transformation changes. For example, in a graphics processing system, the system is required to support the transformation from image data in RGB space to YIQ space and from image data in RGB space to YUV space; in financial or ERP systems, statistics and statistics of various types of data are required. Analysis, these processes need to compile separate codes to achieve different formula calculations. [0003] Since there are often many different data transformations in a system, a large number of different formulas are needed to realize these data transformations, and every time a ne...
