Abstract

The invention provides a data compression method and a device. The method comprises the following steps: calculating a relative value between numerical values in a time series data stream which are separated from a set number of time positions to obtain a relativized data stream; calculating a relative value between numerical values in a time series data stream and a set number of time positions;determining at least one word length shorter than an original data word length of the time series data stream according to a numerical distribution characteristic of a relative value in the relativistic data stream; encoding a relative value in the relativistic data stream according to the determined at least one word length. The compressed data of the time series data stream is generated from anoriginal value for calculating a relative value in the time series data stream and a relative value in the encoded relativistic data stream. The compressed data of the time series data stream is generated from the original value for calculating a relative value in the time series data stream and a relative value in the encoded relativistic data stream. The scheme can reduce the amount of time series data and solve the problem of data storage capacity shortage.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a data compression method and device. Background technique [0002] Time series data is a very common data in daily life and social work. It is a data set obtained by measuring observations at a series of time points at equal time intervals, for example, daily stock closing prices in commercial activities, annual sales of clothing companies, annual precipitation in a city in meteorology, monthly average temperature, etc. Therefore, research on time series data exists in all walks of life. [0003] With the prosperity and development of information technology, more and more real-time sequence data are generated every day. For example, for financial transactions, there may be hundreds or thousands of events per second, and at the same time, data behavior patterns over time and historical data values ​​​​are often as important as current data values, so the amount of data...
