Chapter 1 CHAPTER 1 MySQL Architecture 1 MySQL’s architecture is very different from that of other database servers, and makes it useful for a wide range of purposes. MySQL is not perfect, but it is flexible enough to work well in very demanding environments, such as web applications. At the same time, MySQL can power embedded applications, data warehouses, content indexing and delivery software, highly available redundant systems, online transac- tion processing (OLTP), and much more. To get the most from MySQL, you need to understand its design so that you can work with it, not against it. MySQL is flexible in many ways. For example, you can configure it to run well on a wide range of hardware, and it supports a variety of data types. However, MySQL’s most unusual and important feature is its storage-engine architecture, whose design separates query processing and other server tasks from data storage
