This paper gives a new data compression algorithm——Structured Mixed Compression(SMC) algorithm,which can adapt to the characteristics of real-time database used in financial business. In financial business,the data are dispersed,formatted as text,and there are few duplicate fields in a same data item,so the SMC algorithm mixes words and phrases according to the word frequency,and imports the array to the Huffman tree to compress the business data. According to the test,result shows that the average compression ratio by using SMC algorithm is 15% more than that by using Huffman encoding.
