摘要

Abstract

In real-time database,amount of measuring points and size of data are very huge. The data varies slowly with lots of redundancy , and the system is of high demand for efficiency. So that efficient algorithm of compression is one of the most important aspects of real -time database system. There' re two types of compression algorithm,lossy and lossless ones. It studied data lossy compression and proposed a new algorithm by analyzing and comparing existing lossy compression algorithms. It's based on prediction and dynamic correction to be lossy compression quickly and efficiently for real-time data. Through testing,the algorithm improves the compression rate and decompression accuracy at the same time.
