摘要
首先对常见的实时数据库数据有损线性压缩算法原理进行了讨论,然后提出了一种新的压缩算法——"双旋转门"压缩算法,最后对各个算法的数据压缩能力进行了详细的对比,结果表时该算法与国外实时数据库的专利算法在数据压缩能力达到同样水准。
First,some familiar loss linear compression algorithms in the real-time database are discussed in this paper.Then a new compression algorithm named 'double swing doors' is brought forth.The compression performance of all algorithms is compared at last,and the result is that the new algorithm and proprietary algorithms of foreign real-time databases achieve the same level in data compression performance.
