Abstract

The invention discloses a data processing method and device for formulas. The data processing method comprises the following steps of converting a received formula to be checked input by a user into a postfix expression; building a binary tree of the postfix expression; judging whether tree nodes of the binary tree of the postfix expression meet the preparatory conditions or not; if the tree nodes of the binary tree meet the preparatory conditions, judging that the formula to be checked is correct; if the tree nodes of the binary tree do not meet the preparatory conditions, judging that the formula to be checked is incorrect. According to the data processing method and the device for the formulas, the problem that the correctness of the formula input by the user cannot be judged in real time in the prior art is solved, the correctness of the formula can be judged through carrying out syntax check on the formula input by the user directly, the promptness of feedback is improved, and the user can relatively quickly get tips.

Description

technical field [0001] The present invention relates to the field of data processing, in particular to a data processing method and device for formulas. Background technique [0002] At present, data analysis is widely used in various fields. In data analysis, some indicators need to be mixed and calculated to obtain new analysis data indicators for effect analysis, which is called KPI (Key Performance Indicator, key performance indicator). [0003] For example, in the analysis of advertising indicators, the indicators that need to be monitored include the number of clicks and exposures in the unit time of the advertisement. If the advertiser requests to obtain the real publicity effect of this delivery, it needs to check it through the click-through rate (click-through rate = total number of clicks / total number of impressions); another example is that the advertiser needs to calculate the cost (cost = CPC unit price * number of clicks). A new key performance indicator, na...
