Abstract

The invention discloses a data processing method and device, and relates to the technical field of computers. A specific embodiment of the method comprises the steps of receiving a definition operation on a grammatical rule and a grammatical tag of an index calculation expression, and performing lexical analysis and grammatical analysis on the index calculation expression by using the grammatical rule to obtain a grammatical analysis tree; creating an accessor to traverse the grammar analysis tree, and by analyzing nodes in the grammar analysis tree, replacing grammar tags in the nodes with implementation logic codes of corresponding grammar rules; and determining an index identifier in the index calculation expression, obtaining index data corresponding to the index identifier, processing the index data in sequence according to the position of the node where the implementation logic code is located in the grammar analysis tree, obtaining processing result data, and returning the processing result data. According to the implementation mode, for the index definitors capable of giving the data expressions, efficient definition and efficient execution of the new indexes can be achieved without writing redundant codes, and the learning cost and the operation cost are low.

Description

technical field [0001] The present invention relates to the field of computer technology, and in particular, to a data processing method and device. Background technique [0002] In the statistical processing of data, there are scenarios in which derived indicators need to be calculated based on basic indicators, for example, the per capita GDP of a region is calculated based on the GDP (Gross Domestic Product) and population data of a region. At present, it is mainly implemented through offline job pre-computation and configuration scripts. However, these two methods have the problems of high deployment cost or high learning cost, and redundant and time-consuming coding. SUMMARY OF THE INVENTION [0003] In view of this, the embodiments of the present invention provide a data processing method and device, which can at least solve the problems of high deployment cost, high learning cost, and redundant and time-consuming code writing in the existing technology for calculati...
