| Abstract: | 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. |
