本书为英文版，以下是简介： SQL Server 2008 represents a sizable jump forward in scalability, performance, and usability for the DBA, developer, and business intelligence (BI) developer. It is no longer unheard of to have 20-terabyte databases running on a SQL Server. SQL Server administration used to just be the job of a database administrator (DBA), but as SQL Server proliferates throughout smaller companies, many developers have begun to act as administrators as well. Additionally, some of the new features in SQL Server are more developer-centric, and poor configuration of these features can result in poor performance. SQL Server now enables you to manage the policies on hundreds of SQL Servers in your environment as if you were managing a single instance. We’ve provided a comprehensive, tutorial-based book to get you over the learning curve of how to configure and administer SQL Server 2008. Whether you’re an administrator or developer using SQL Server, you can’t avoid wearing a DBA hat at some point. Developers often have SQL Server on their own workstations and must provide guidance to the administrator about how they’d like the production configured. Oftentimes, they’re responsible for creating the database tables and indexes. Administrators or DBAs support the production servers and often inherit the database from the developer. This book is intended for developers, DBAs, and casual users who hope to administer or may already be administering a SQL Server 2008 system and its business intelligence features, such as Integration Services. This book is a professional book, meaning the authors assume that you know the basics about how to query a SQL Server and have some rudimentary concepts of SQL Server already. For example, this book does not show you how to create a database or walk you through the installation of SQL Server using the wizard. Instead, the author of the installation chapter may provide insight into how to use some of the more advanced concepts of the installation. Although this book does not cover how to query a SQL Server database, it does cover how to tune the queries you’ve already written. The first ten chapters of the book are about administering the various areas of SQL Server, including the developer and business intelligence features. Chapter 1 briefly covers the architecture of SQL Server and the changing role of the DBA. Chapters 2 and 3 dive into best practices on installing and upgrading to SQL Server 2008. Managing your SQL Server database instance is talked about in Chapter 4. This chapter also describes some of the hidden tools you may not even know you have. Once you know how to manage your SQL Server, you can learn in Chapter 5 how to automate many of the redundant monitoring and maintenance tasks. This chapter also discusses best practices on configuring SQL Server Agent. Chapters 6 and 7 cover how to properly administer and automate many tasks inside of the Microsoft business intelligence products, such as Integration Services and Analysis Services. Developers will find that Chapter 8 is very useful, as it covers how to administer the development features, such as SQL CLR. Chapter 9 explains how to secure your SQL Server from many common threats and how to create logins and users. Chapter 10 covers how to create a SQL Server project and do proper change management in promoting your scripts through the various environments. It also covers the Policy-Based Management framework in SQL Server. Chapters 11 through 15 make up the performance tuning part of the book. Chapter 11 discusses how to choose the right hardware configuration for your SQL Server in order to achieve optimal performance. After the hardware and operating system is configured, Chapter 12 shows you how to optimize your SQL Server instance for the best performance. Chapter 13 describes how to monitor your SQL Server instance for problematic issues such as blocking and locking. Chapters 14 and 15 discuss how to optimize the T-SQL that accesses your tables and then how to index your tables appropriately. Chapters 16 through 20 consist of the high-availability chapters of the book. Chapter 16 covers how to use the various forms of replication, while database mirroring is covered in Chapter 17. Classic issues and best practices with backing up and recovering your database are discussed in Chapter 18. Chapter 19 dives deeply into the role of log shipping in your high-availability strategy, and Chapter 20 presents a step-by-step guide to clustering your SQL Server and Windows 2008 server. This edition of the book covers all the same great information we covered in the last book, and we’ve added loads of new content for SQL Server 2008, which adds numerous new features to improve the DBA’s life. In short, the new version of SQL Server focuses on improving your efficiency, the scale of your server, and the performance of your environment, so you can do more in much less time, and with fewer resources and people. This means you can manage many servers at one time using Policy-Based Management, scale your I/O load using compression, and collect valuable information about your environment using data collectors, to name just a few key new features. To follow the examples in this book, you will need to have SQL Server 2008 installed. If you wish to learn how to administer the business intelligence features, you need to have Analysis Services and the Integration Services components installed. You need a machine that can support the minimum hardware requirements to run SQL Server 2008; and you also need the AdventureWorks2008 and AdventureWorksDW2008 databases installed. Instructions for accessing these databases can be found in the ReadMe file on this book’s Web site. Some features in this book (especially in the high-availability part) require the Enterprise or Developer Edition of SQL Server. If you do not have this edition, you will still be able to follow through some of the examples in the chapter with Standard Edition.

本书是一本介绍数据结构与算法的优秀书籍。 本书系统介绍了C++面向对象程序设计、算法复杂度、链表、栈、队列、递归、树、图、排序和查找算法、散列技术、数据压缩算法、内存管理等内容；尤其对递归算法进行了深入剖析。在附录中详细介绍了大O符号与标准模板库；在大多数章中提供了相应的实例分析和程序设计作业。 本书适合作为计算机软件专业或其他相关专业的教科书。对于需要参加计算机考试，或者希望自学计算机软件开发的人员也有非常大的帮助。 本书以案例驱动的方式，全面介绍了计算机科学的重要领域——数据结构，并以目前应用最为广泛的C++语言实现相关的算法。书中不仅特别强调了数据结构与算法之间的联系，包括算法复杂度分析，而且介绍了面向对象程序设计环境中的数据结构，重点讲述了隐藏信息封装和分解处理的原理。 与同类教材相比，本书不仅提供了任何软件系统从设计、实现、测试到维护所需的基本概念，详尽地讨论了同类教材中少见的内存管理和数据压缩主题，还将对递归的讨论置于运行时堆栈环境中，使读者对递归有更明晰的理解。此外，本书各章（第2章除外）提供了一个可供测试的程序分析以演示特定的数据结构和算法，并将相关C++标准模板库应用在程序分析中。贯穿全书的C++示例代码演示了数据结构的实践价值，精心设计的程序设计课后作业可以使学生能够学以致用。因此，无论是对数据结构的初学者，还是对有一定基础的学生，本书都是一本不可多得的新型数据结构教材。
