A poorly performing database application not only costs users time, but also has an impact on other applications running on the same computer or the same network. SQL Tuning provides an essential next step for SQL developers and database administrators who want to extend their SQL tuning expertise and get the most from their database applications.There are two basic issues to focus on when tuning SQL: how to find and interpret the execution plan of an SQL statement and how to change SQL to get a specific alternate execution plan. SQL Tuning provides answers to these questions and addresses a third issue that's even more important: how to find the optimal execution plan for the query to use.Author Dan Tow outlines a timesaving method he's developed for finding the optimum execution plan--rapidly and systematically--regardless of the complexity of the SQL or the database platform being used. You'll learn how to understand and control SQL execution plans and how to diagram SQL queries to deduce the best execution plan for a query. Key chapters in the book include exercises to reinforce the concepts you've learned. SQL Tuning concludes by addressing special concerns and unique solutions to "unsolvable problems."Whether you are a programmer who develops SQL-based applications or a database administrator or other who troubleshoots poorly tuned applications, SQL Tuning will arm you with a reliable and deterministic method for tuning your SQL queries to gain optimal performance.

New York Times Book Review Editor’s Choice; Real Simple Best of the Month; Library Journal Editors’ Pick In the spirit of Battle Hymn of the Tiger Mother, Bringing up Bébé, and The Smartest Kids in the World, a hard-hitting exploration of China’s widely acclaimed yet insular education system that raises important questions for the future of American parenting and education When students in Shanghai rose to the top of international rankings in 2009, Americans feared that they were being "out-educated" by the rising super power. An American journalist of Chinese descent raising a young family in Shanghai, Lenora Chu noticed how well-behaved Chinese children were compared to her boisterous toddler. How did the Chinese create their academic super-achievers? Would their little boy benefit from Chinese school? Chu and her husband decided to enroll three-year-old Rainer in China’s state-run public school system. The results were positive—her son quickly settled down, became fluent in Mandarin, and enjoyed his friends—but she also began to notice troubling new behaviors. Wondering what was happening behind closed classroom doors, she embarked on an exploratory journey, interviewing Chinese parents, teachers, and education professors, and following students at all stages of their education. What she discovered is a military-like education system driven by high-stakes testing, with teachers posting rankings in public, using bribes to reward students who comply, and shaming to isolate those who do not. At the same time, she uncovered a years-long desire by government to alleviate its students’ crushing academic burden and make education friendlier for all. The more she learns, the more she wonders: Are Chinese children—and her son—paying too high a price for their obedience and the promise of future academic prowess? Is there a way to appropriate the excellence of the system but dispense with the bad? What, if anything, could Westerners learn from China’s education journey? Chu’s eye-opening investigation challenges our assumptions and asks us to consider the true value and purpose of education.

World Development Report 1994 examines the link between infrastructure and development and explores ways in which developing countries can improve both the provision and the quality of infrastructure services. In recent decades, developing countries have made substantial investments in infrastructure, achieving dramatic gains for households and producers by expanding their access to services such as safe water, sanitation, electric power, telecommunications, and transport. Even more infrastructure investment and expansion are needed in order to extend the reach of services - especially to people living in rural areas and to the poor. But as this report shows, the quantity of investment cannot be the exclusive focus of policy. Improving the quality of infrastructure service also is vital. Both quantity and quality improvements are essential to modernize and diversify production, help countries compete internationally, and accommodate rapid urbanization. The report identifies the basic cause of poor past performance as inadequate institutional incentives for improving the provision of infrastructure. To promote more efficient and responsive service delivery, incentives need to be changed through commercial management, competition, and user involvement. Several trends are helping to improve the performance of infrastructure. First, innovation in technology and in the regulatory management of markets makes more diversity possible in the supply of services. Second, an evaluation of the role of government is leading to a shift from direct government provision of services to increasing private sector provision and recent experience in many countries with public-private partnerships is highlighting new ways to increase efficiency and expand services. Third, increased concern about social and environmental sustainability has heightened public interest in infrastructure design and performance.

Principles of Computer System Design is the first textbook to take a principles-based approach to the computer system design. It identifies, examines, and illustrates fundamental concepts in computer system design that are common across operating systems, networks, database systems, distributed systems, programming languages, software engineering, security, fault tolerance, and architecture.Through carefully analyzed case studies from each of these disciplines, it demonstrates how to apply these concepts to tackle practical system design problems. To support the focus on design, the text identifies and explains abstractions that have proven successful in practice such as remote procedure call, client/service organization, file systems, data integrity, consistency, and authenticated messages. Most computer systems are built using a handful of such abstractions. The text describes how these abstractions are implemented, demonstrates how they are used in different systems, and prepares the reader to apply them in future designs.The book is recommended for junior and senior undergraduate students in Operating Systems, Distributed Systems, Distributed Operating Systems and/or Computer Systems Design courses; and professional computer systems designers. - Concepts of computer system design guided by fundamental principles - Cross-cutting approach that identifies abstractions common to networking, operating systems, transaction systems, distributed systems, architecture, and software engineering - Case studies that make the abstractions real: naming (DNS and the URL); file systems (the UNIX file system); clients and services (NFS); virtualization (virtual machines); scheduling (disk arms); security (TLS) - Numerous pseudocode fragments that provide concrete examples of abstract concepts - Extensive support. The authors and MIT OpenCourseWare provide on-line, free of charge, open educational resources, including additional chapters, course syllabi, board layouts and slides, lecture videos, and an archive of lecture schedules, class assignments, and design projects

The first edition of The Internal Auditing Handbook received wide acclaim from readers and became established as one of the definitive publications on internal auditing. The second edition was released soon after to reflect the rapid progress of the internal audit profession. There have been a number of significant changes in the practice of internal auditing since publication of the second edition and this revised third edition reflects those changes. The third edition of The Internal Auditing Handbook retains all the detailed material that formed the basis of the second edition and has been updated to reflect the Institute of Internal Auditor’s (IIA) International Standards for the Professional Practice of Internal Auditing. Each chapter has a section on new developments to reflect changes that have occurred over the last few years. The key role of auditors in reviewing corporate governance and risk management is discussed in conjunction with the elevation of the status of the chief audit executive and heightened expectations from boards and audit committees. Another new feature is a series of multi-choice questions that have been developed and included at the end of each chapter. This edition of The Internal Auditing Handbook will prove to be an indispensable reference for both new and experienced auditors, as well as business managers, members of audit committees, control and compliance teams, and all those who may have an interest in promoting corporate governance.
