1)The big string ,i mean the string is large enough,about 8-10k
This doesn’t strike me as "big". 2)I use the SqlServer ( varchar(max) ) to store the string.SQLServer should have not trouble handling those strings. 3)I just compress common string ,eg.:...Any of the suggested compression alternatives should work for you. Based on the example you provide I assume that you will obtain excellent compression ratios. I would like to draw your attention to one more alternative: RLE which stands for Run Length Encoding. It doesn’t give you a great compression ration but it’s very simple and therefore fast. I have found a Perl implementation for it which can be found here (I did not tested it though) In reply to Re^3: How to "zip" a big string to small ?
