Coding method and system based on order relation in data distribution

The invention relates to a coding method and system based on a data distribution inorder relation, in particular to a coding method and system based on the data distribution inorder relation, and aims to solve the problems that data dimensions are exploded during coding of existing computer coding, particularly when a large number of classes of classification variables exist, calculation and storage resources are wasted, and the coding efficiency is high. And the calculation efficiency is reduced. Aiming at a certain discrete attribute to be coded in the computer data table, obtaining all value pairs of the discrete attribute, and calculating a distribution distance between values in each value pair of the discrete attribute by adopting distribution of all discrete attribute values of each value in each value pair; all values in the discrete attributes are traversed to obtain all paths, the path with the shortest distance is selected as the shortest path, and the shortest path distance is obtained; and coding
