Abstract

Abstract: Real-time database has been widely applied in industrial process control field, in which historical data costs vast space. In order to increase the capacity of database while keeping the characteristic of high speed, data compression technology is adopted into real-time database. This paper designs a new lossless data compression algorithm for historical data of real-time database which is based on LZ algorithm. The experiments indicate that this algorithm achieves small amount of computation, high compression ratio and fast compression speed.

Key words: real-time database, data compression, lossless compression algorithm
