Principles of Transaction Processing is a comprehensive guide to developing applications, designing systems, and evaluating engineering products. The book provides detailed discussions of the internal workings of transaction processing systems, and it discusses how these systems work and how best to utilize them. It covers the architecture of Web Application Servers and transactional communication paradigms.The book is divided into 11 chapters, which cover the following: Overview of transaction processing application and system structureSoftware abstractions found in transaction processing systemsArchitecture of multitier applications and the functions of transactional middleware and database serversQueued transaction processing and its internals, with IBM's Websphere MQ and Oracle's Stream AQ as examplesBusiness process management and its mechanismsDescription of the two-phase locking function, B-tree locking and multigranularity locking used in SQL database systems and nested transaction lockingSystem recovery and its failuresTwo-phase commit protocolComparison between the tradeoffs of replicating servers versus replication resourcesTransactional middleware products and standardsFuture trends, such as cloud computing platforms, composing scalable systems using distributed computing components, the use of flash storage to replace disks and data streams from sensor devices as a source of transaction requests. The text meets the needs of systems professionals, such as IT application programmers who construct TP applications, application analysts, and product developers. The book will also be invaluable to students and novices in application programming. - Complete revision of the classic "non mathematical" transaction processing reference for systems professionals - Updated to focus on the needs of transaction processing via the Internet-- the main focus of business data processing investments, via web application servers, SOA, and important new TP standards - Retains the practical, non-mathematical, but thorough conceptual basis of the first edition
The best introduction to transaction processing systems I have ever read." - K.Torp, ACM Computing Reviews, November 1997 Principles of Transaction Processing is a clear, concise guide for anyone involved in developing applications, evaluating products, designing systems, or engineering products. This book provides an understanding of the internals of transaction processing systems, describing how they work and how best to use them. It includes the architecture of transaction processing monitors, transactional communications paradigms, and mechanisms for recovering from transaction and system failures. Use of transaction processing systems in business, industry, and government is increasing rapidly; the emergence of electronic commerce on the Internet is creating new demands. As a result, many developers are encountering transaction processing applications for the first time and need a practical explanation of techniques. Software engineers who build and market operating systems, communications systems, programming tools, and other products used in transaction processing applications will also benefit from this thorough presentation of principles. Rich with examples, it describes commercial transaction processing systems, transactional aspects of database servers, messaging systems, Internet servers, and object-oriented systems, as well as each of their subsystems. Features: Easy-to-read descriptions of fundamentals. Real world examples illustrating key points. Focuses on practical issues faced by developers. Explains most major products and standards, including IBM's CICS, IMS, and MQSeries; X/Open's XA, STDL, and TX; BEA Systems' TUXEDO; Digital's ACMS; Transarc's Encina; AT&T/NCR's TOP END; Tandem's Pathway/TS; OMG's OTS; and Microsoft's Microsoft Transaction Server.
Operating Systems deals with the fundamental concepts and principles that govern the behavior of operating systems. Many issues regarding the structure of operating systems, including the problems of managing processes, processors, and memory, are examined. Various aspects of operating systems are also discussed, from input-output and files to security, protection, reliability, design methods, performance evaluation, and implementation methods. Comprised of 10 chapters, this volume begins with an overview of what constitutes an operating system, followed by a discussion on the definition and properties of the basic unit of computation within an operating system, the process. The reader is then introduced to processor allocation schemes as well as various classes of scheduling disciplines and their implementations; memory management functions; and virtual memory. Subsequent chapters focus on input-output and files; protection in an operating system; and design and implementation of an operating system. The book concludes by describing two operating systems to help the reader visualize how the major components of a system interact in a complete system: the Venus Operating System developed by MITRE Corp. and the SUE nucleus, designed at the University of Toronto. This monograph is intended for fourth-year undergraduates and first-year graduate students, as well as lecturers who plans to institute a course on operating systems.
The thoroughly updated Fifth Edition of this practical handbook provides the essential information that clinicians and patients need to choose the best contraceptive method for the patient's age and medical, social, and personal characteristics.
Outstanding text, oriented toward computer solutions, stresses errors in methods and computational efficiency. Problems — some strictly mathematical, others requiring a computer — appear at the end of each chapter.
First published in 1981, this book provides a basic introduction to the sociology of education. It brings together many of the principal arguments in order to help the student reach an understanding of the multitude of conflicting opinions, theoretical positions and biases within the field. The work considers the structures within which the child, the family and the classroom are located, focusing on the theory and the ways in which they can be used to explain the workings of the educational system. It introduces not only the work of classical educational sociologists such as Durkheim, Weber and Marx, but also more recent scholars such as Halsey, Becker and Althusser. With a global coverage, the book emphasizes the implications of the developments of the sociology of education for educational policy.
