If you need to reprint, please keep the author and source information: http://blog.csdn.net/jmppok/article/details/38121115 During network transmission, the most important concern is the transmission efficiency. The most effective way to improve transmission efficiency is to compress the transmitted data. However, it takes a certain amount of time to compress data. Is it possible to improve effi

Summary of five commonly used picture formats and whether they have data compressionDisclaimer: Reference Please specify source http://blog.csdn.net/lg1259156776/Description: This article focuses on the five most common and most commonly used image formats: bmp,png,jpeg,jpeg200, and GIF. The first step before image processing related applications is to be able to read these image files, although many development tool support libraries such as OPENCV h

When you hear this word about Oracle Database compression, you must think of saving hard disk space. Yes, it is used to do this, but extending it out not only saves hard disk space, it can also save bandwidth and memory usage (cpu consumption is slightly reduced because more computing value operations are required, but in most environments the cpu is idle, so you can ignore it ).Basic compression is provide

For row-stored tables and indexes, using data compression can help reduce the size of the database. In addition to saving space, data compression can also help improve the performance of I/O-intensive workloads because the data is stored in fewer pages and queries require fe

New Ideas The compression model we discussed in chapter 3 and Chapter 4 was designed based on statistics on the Occurrence Frequency of a single character in the information until 70At the end of the age, this idea had been dominant in the field of data compression. In our opinion today, this situation seems a bit ridiculous to some extent, but this is the case,

Key ConceptsConfiguration data compression can be implemented in both SSMS and T-SQL statements.Table and Index compressionFor row storage tables and indexes, using data compression can help reduce the size of the database. In addition to saving space, data
