Pattern languages of program design

Patterns remain one of the most important new technologies contributing to software engineering, system design, and development. All indications are that patterns will continue to grow in significance as more and more developers rely on reusable design patterns to help them achieve quick, cost-effective delivery of applications. This volume is a collection of the current best practices and trends in the patterns community. The patterns contained in this book provide effective, tested, and versatile software design solutions for developers in all domains, institutions, and organizations. The third in a series of books documenting patterns for professional software developers, this volume continues the tradition of informational excellence established by the first two volumes. Pattern Languages of Program Design 3 differs from the previous two volumes in that it includes international submissions, gathering the best papers from both PloP '96 and EuroPLoP '96. It covers a wide range of pattern-related subjects, and patterns are arranged by topic so software engineers can easily select those of greatest relevance to their needs and application domains.This book goes beyond teaching software engineers that design patterns are powerful tools to impart understanding--it shows where and when patterns are best applied. 0201310112B04062001

Design patterns have moved into the mainstream of commercial software development as a highly effective means of improving the efficiency and quality of software engineering, system design, and development. Patterns capture many of the best practices of software design, making them available to all software engineers. The fourth volume in a series of books documenting patterns for professional software developers, Pattern Languages of Program Design 4 represents the current and state-of-the-art practices in the patterns community. The 29 chapters of this book were each presented at recent PLoP conferences and have been explored and enhanced by leading experts in attendance. Representing the best of the conferences, these patterns provide effective, tested, and versatile software design solutions for solving real-world problems in a variety of domains. This book covers a wide range of topics, with patterns in the areas of object-oriented infrastructure, programming strategies, temporal patterns, security, domain-oriented patterns, human-computer interaction, reviewing, and software management.Among them, you will find: *The Role object *Proactor *C++ idioms *Architectural patterns for security *Reports *Composing multimedia artifacts *Customer interaction As patterns evolve beyond the realm of research into the world of practical software development, more and more developers are discovering that reusable design patterns (such as those contained in this volume) can help them achieve faster, more cost-effective delivery of their applications. 0201433044B04062001

Design patterns have moved into the mainstream of professional software development as a highly effective means of improving the quality of software engineering, system design, and development, as well as the communication among the people building them. Patterns capture many of the best practices of software design, making them available to all software engineers. The fifth volume in a series of books documenting patterns for professional software developers, Pattern Languages of Program Design 5 covers current software development best practices distilled by the patterns community. The material presented in the nineteen chapters of this book distills first-rate patterns, which were workshopped at recent PLoP conferences and rigorously reviewed and enhanced by leading experts in attendance. Representing the best of the conferences, these patterns provide effective, tested, and versatile software design solutions for solving real-world problems in a variety of domains. Pattern Languages of Program Design 5 covers a wide range of topics, particularly the areas of object-oriented systems, programming techniques, temporal patterns, security, domain-oriented patterns, human-computer interaction, software management, and software patterns. Among them, you will find patterns addressing: Object-oriented systems Middleware Concurrency and resource management problems Distributed systems Mobile telephony Web-based applications Extensibility and reuse Meta-patterns As patterns continue to capture insight from many areas of practical software development, more and more developers are discovering that using patterns improves communication and helps them build better software.
