Abstract

The invention discloses a method and a device for data compression. The device comprises a calling module for calling a compression data statistic table, a selection module and a compression module, wherein one-to-one corresponding relations among data format, compression configuration and compression effect information are stored in the compression data statistic table; the selection module is used for acquiring corresponding compression effect information from the compression data statistic table according to the data format of data to be compressed and the compression mode selected by a user and selecting the compression configuration corresponding to the compression mode according to the compression effect information, and the compression mode comprises a compression speed priority mode and a compression volume priority mode; the compression module is used for compressing the data to be compressed according to the compression configuration and acquiring a compressed data packet. Based on the technical scheme of the method and the device for data compression, the most appropriate compression configuration can be automatically matched for users according to the requirements of the users, so that the purposes of having the fastest compression speed or minimal compression volume and improving the use experience of the users can be achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data compression method and device. Background technique [0002] In the prior art, a compression tool changes file content and data through a certain compression algorithm, so that the data occupies less storage space. Specifically, ordinary files generally contain a certain amount of repeated data, and these repeated data often occupy multiple times the storage space. It only takes up one storage space, and when decompressing, the compressed file is restored through the corresponding decompression algorithm, which generally belongs to lossless compression. For example, if a text file contains multiple identical words "People's Republic of China", after being compressed by a compression tool, it only needs to occupy one storage space for storage, thereby achieving the purpose of shrinking the file. [0003] In addition, the compression tool can not only help users save spa...
