Abstract

The invention provides a data compression method and device and a data decompression method and device, and the method comprises the steps: dividing original data into a plurality of to-be-compresseddata blocks, and enabling each to-be-compressed data block to be stored according to a plurality of preset bytes; according to data information of non-zero bytes in each to-be-compressed data block, determining first compressed data corresponding to the to-be-compressed data block; and splicing the first compressed data corresponding to the plurality of to-be-compressed data blocks to obtain second compressed data corresponding to the original data, thereby reducing the storage size of the data, saving the storage space of the data, and improving the storage efficiency and transmission efficiency of the data.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data compression method and device, and a decompression method and device. Background technique [0002] With the vigorous development of industrial big data, massive data should be generated, which increases the demand for data storage space. Based on this, when data is stored, the data is processed in advance to store more data in the same storage space. data. [0003] For example, by compressing the data. Data compression refers to reducing the amount of data to reduce storage space without losing useful information to improve data transmission efficiency, or to reorganize data according to a certain algorithm to reduce data redundancy and storage space a technical approach. [0004] However, most of the current data compression methods are aimed at compressing larger file data, and the compression effect for some small files is often not good. Con...
