说明：  数据库的性能优化远不是按照厂家所列的有关指南通过短短的几步就可以达到的。 要获得最大的优化效果，需要有广泛而深入的基本调优原理的知识，有按系统的方法搜集数据的能力，以及让系统运行更快速的技巧。这既是一门艺术，也是一门科学，而本书将帮助读者获得这方面的技能，从而可以达到对基于各种硬件和操作系统之上的各种数据库系统进行调优的目的。而且，这些技术辅以书中的有关实验结果，可以帮助读者准确评估有关的数据库产品并做出正确的选择。 《数据库性能调优——原理与技术》可以作为高年级本科生和研究生的教材，对从事数据库研究和开发的科研人员和工程技术人员也是一本难得的参考书。
(Database performance optimization is far from set in accordance with relevant guidelines by manufacturers of short steps to reach. To get the most optimal results, the need for extensive and in-depth knowledge of basic tuning principles, there are methods of collecting data according to system capacity, and let the system run faster techniques. This is both an art and a science, and this book will help readers gain the skills in this area, which can achieve a variety of hardware and operating systems based on a variety of database system tuning purposes. Moreover, these technologies combined with the experimental results of the book to help readers assess the accuracy of database products and make the right choice. "Database performance tuning- Theory and Technology" can be used as undergraduate and graduate teaching materials in database research and development scientists and engineers is also a rare reference books.)
