SQL Server 2005 SP2 brought us the vardecimal function. At that time, a new storage format-vardecimal was introduced for the decimail and numeric data types. The vardecimal storage format allows storage of the decimal and numeric data types as a variable length column. This feature allows the original fixed-length decimal data to be stored in a variable-length format in the data file. It is said that this feature can save 30% of the space for a typical data warehouse, SQL Server 2008 further enh

Lossless data compression is a wonderful thing. Think about it. A string of arbitrary data can be converted into data with only 1/2-1/5 length according to certain rules, it sounds really cool to restore to the original form according to the corresponding rules. Half a year ago, I had a hard time learning the curve when I was a beginner in vc. I was disappointed and dissatisfied with the MFC and SDK. Although these are not easy to learn, there is no s

The RLE (Run length Encoding) stroke length compression algorithm (also known as the duration compression algorithm) is the earliest and simplest lossless data compression algorithm. The basic idea of the RLE algorithm is to divide the data into two cases according to the linear sequence: one is a continuous block of repeated data, the other is a continuous block

GZIP (Gnu-zip) is a compression technique. The page size can be turned into 30% or smaller after gzip compression. This way the user will feel very happy when browsing!To achieve the GZIP compression page requires a common browser and server support, is actually the server compression, uploaded to the browser after the

IIS enabled gzip compression, the original thought you can compress all the files, including HTML, CSS, JS, pictures of these files, but when I check, I found that is not the case, compressed only HTML files, and CSS, JS and not compression. Detection results in the speed diagnostics of the Web site of the card network: The HTML page has successfully enabled gzip co
