Software Expert Kent Beck Presents a Catalog of Patterns Infinitely Useful for Everyday Programming Great code doesn’t just function: it clearly and consistently communicates your intentions, allowing other programmers to understand your code, rely on it, and modify it with confidence. But great code doesn’t just happen. It is the outcome of hundreds of small but critical decisions programmers make every single day. Now, legendary software innovator Kent Beck—known worldwide for creating Extreme Programming and pioneering software patterns and test-driven development—focuses on these critical decisions, unearthing powerful “implementation patterns” for writing programs that are simpler, clearer, better organized, and more cost effective. Beck collects 77 patterns for handling everyday programming tasks and writing more readable code. This new collection of patterns addresses many aspects of development, including class, state, behavior, method, collections, frameworks, and more. He uses diagrams, stories, examples, and essays to engage the reader as he illuminates the patterns. You’ll find proven solutions for handling everything from naming variables to checking exceptions.

Learn to build configuration file readers, data readers, model-driven code generators, source-to-source translators, source analyzers, and interpreters. You don't need a background in computer science--ANTLR creator Terence Parr demystifies language implementation by breaking it down into the most common design patterns. Pattern by pattern, you'll learn the key skills you need to implement your own computer languages. Knowing how to create domain-specific languages (DSLs) can give you a huge productivity boost. Instead of writing code in a general-purpose programming language, you can first build a custom language tailored to make you efficient in a particular domain. The key is understanding the common patterns found across language implementations. Language Design Patterns identifies and condenses the most common design patterns, providing sample implementations of each. The pattern implementations use Java, but the patterns themselves are completely general. Some of the implementations use the well-known ANTLR parser generator, so readers will find this book an excellent source of ANTLR examples as well. But this book will benefit anyone interested in implementing languages, regardless of their tool of choice. Other language implementation books focus on compilers, which you rarely need in your daily life. Instead, Language Design Patterns shows you patterns you can use for all kinds of language applications. You'll learn to create configuration file readers, data readers, model-driven code generators, source-to-source translators, source analyzers, and interpreters. Each chapter groups related design patterns and, in each pattern, you'll get hands-on experience by building a complete sample implementation. By the time you finish the book, you'll know how to solve most common language implementation problems.

The keynote addresses, by Professor Colette Roland and Mr Ian Graham, are also included. The acceptance rate for papers was around 47%. The papers for the Industry Day were invited papers. The keynote paper by Professor Roland analyses the challenges in object modelling, particularly the impact of requirements engineering for conceptual modelling. She suggests innovative research perspectives to enhance and extend object oriented approaches in order to deal with the emerging area of requirements engineering. The keynote paper presented by Mr. Graham focuses on the problems and solutions for adopting use cases. In his paper, Graham illustrates the theoretical issues and practical problems of use cases, and highlights them using examples. The papers included in this volume cover different aspects of object modelling, object oriented software development, object databases, and interoperability. In the modelling session, Ram, et al. outline an extended object model to tackle the problems of capturing complex requirements of office information systems. Simons' paper concentrates on core object modelling concepts and presents a mathematical theory of class.

In OBJECT THINKING, esteemed object technologist David West contends that the mindset makes the programmer—not the tools and techniques. Delving into the history, philosophy, and even politics of object-oriented programming, West reveals how the best programmers rely on analysis and conceptualization—on thinking—rather than formal process and methods. Both provocative and pragmatic, this book gives form to what’s primarily been an oral tradition among the field’s revolutionary thinkers—and it illustrates specific object-behavior practices that you can adopt for true object design and superior results. Gain an in-depth understanding of: Prerequisites and principles of object thinking. Object knowledge implicit in eXtreme Programming (XP) and Agile software development. Object conceptualization and modeling. Metaphors, vocabulary, and design for object development. Learn viable techniques for: Decomposing complex domains in terms of objects. Identifying object relationships, interactions, and constraints. Relating object behavior to internal structure and implementation design. Incorporating object thinking into XP and Agile practice.

Achieve Breakthrough Business Flexibility and Agility by Integrating SOA and BPM Thousands of enterprises have adopted Service Oriented Architecture (SOA) based on its promise to help them respond more rapidly to changing business requirements by composing new solutions from existing business services. To deliver on this promise, however, companies need to integrate solid but flexible Business Process Management (BPM) plans into their SOA initiatives. Dynamic SOA and BPM offers a pragmatic, efficient approach for doing so. Top IBM® SOA architect Marc Fiammante takes you step-by-step through combining BPM and SOA, and using them together to build a more flexible, dynamic enterprise. Throughout the book, he emphasizes hands-on solutions based on his experience supporting dozens of enterprise SOA implementations. Practical from start to finish, Dynamic SOA and BPM squarely addresses two of the most critical challenges today’s IT executives, architects, and analysts face: implementing BPM as effectively as possible and deriving more value from their SOA investments. Coverage Includes Moving from simplified integration to dynamic processes: realizing the full business value of services Streamlining enterprise architecture to accelerate business and IT alignment Implementing dynamic business processes based on small, flexible modules that can be quickly modeled, tested, delivered, and improved Planning for services and information variability to limit the impact of change on processes and other consumers of services Providing an integration layer between consumers and providers that addresses issues classical Enterprise Service Bus (ESB) approaches cannot solve alone Tooling and practices for the development, management, and monitoring of the complete SOA/BPM life cycle

2012 Jolt Award Finalist! Even experienced software professionals find it difficult to apply patterns in ways that deliver substantial value to their organizations. In Elemental Design Patterns, Jason McC. Smith addresses this problem head-on, helping developers harness the true power of patterns, map them to real software implementations more cleanly and directly, and achieve far better results. Part tutorial, part example-rich cookbook, this resource will help developers, designers, architects, and analysts successfully use patterns with a wide variety of languages, environments, and problem domains. Every bit as important, it will give them a deeper appreciation for the work they’ve chosen to pursue. Smith presents the crucial missing link that patterns practitioners have needed: a foundational collection of simple core patterns that are broken down to their core elements. If you work in software, you may already be using some of these elemental design patterns every day. Presenting them in a comprehensive methodology for the first time, Smith names them, describes them, explains their importance, helps you compare and choose among them, and offers a framework for using them together. He also introduces an innovative Pattern Instance Notation diagramming system that makes it easier to work with patterns at many levels of granularity, regardless of your goals or role. If you’re new to patterns, this example-rich approach will help you master them piece by piece, logically and intuitively. If you’re an experienced patterns practitioner, Smith follows the Gang of Four format you’re already familiar with, explains how his elemental patterns can be composed into conventional design patterns, and introduces highly productive new ways to apply ideas you’ve already encountered. No matter what your level of experience, this infinitely practical book will help you transform abstract patterns into high-value solutions.

Architekturen von Softwaresystemen sollen einfach erweiterbar und weitestgehend standardisiert sein, damit die Entwickler sich leicht über Architekturen austauschen können. Für den objektorientierten Entwurf haben sich zahlreiche wertvolle Architektur- und Entwurfsmuster herausgebildet. Diese Muster basieren auf objektorientierten Prinzipien wie dem Prinzip der Dependency Inversion. Daher werden zuerst die wichtigsten objektorientierten Prinzipien erklärt. Anschließend wird gezeigt, wie diese objektorientierten Prinzipien in den verschiedenen Architektur- und Entwurfsmustern umgesetzt werden. Alle vorgestellten Muster werden durch lauffähige Beispiele in Java illustriert.

Unternehmen, die informatikgestütztes Datenmanagement einsetzen, sind – mehr denn je – mit umfangreichen Datenmengen (etwa Produkt-, Workflow- und Personaldaten) konfrontiert, die relevant für ihre strategischen Entscheidungen sind. Eine große Herausforderung besteht darin, diese komplexen Datenbestände in ihrem Anwendungskontext zu visualisieren, zu filtern und zu interpretieren, um sie schließlich effektiv und effizient verwenden zu können. Vor diesem Problemhintergrund zeigen drei praxisbezogene Fallstudien mehrere integrale, konzeptuell-programmatische Lösungsansätze aus der interdisziplinären Perspektive der Mensch-Computer Interaktion auf. Ein besonderes Augenmerk gilt dem – hinsichtlich »Usability« und »User Experience« – vielversprechenden Ansatz »Skalierbarer Benutzungsschnittstellen« (Zoomable User Interfaces). Die konzeptuellen und gestalterischen Erkenntnisse führen zur Ableitung verallgemeinerbarer Problemlösungsansätze, die in Form von »Patterns« für den praktischen Einsatz dokumentiert sind. Studierenden und Wissenschaftlern bietet die theoretische und methodische Konfundierung wesentliche Grundlagen und innovative Anregungen für eigene Studien. Die ermittelten »Patterns« unterstützen Consultants und Praktiker bei der Entwicklung und Auswahl von geeigneten Visualisierungs-, Interaktions-, Such- und Filtertechniken für komplexe Informationsräume in der betrieblichen Praxis.

Giving particular attention to intergovernmental working relationships, this revised edition of Federalism and Environmental Policy has been significantly updated to reflect the changes that have taken place since the highly praised first edition. Denise Scheberle examines reasons why environmental laws seldom work out exactly as planned. Casting federal-state working relationships as "pulling together," "coming apart," or somewhere in-between, she provides dozens of observations from federal and state officials. This study also suggests that implementation of environmental policy is a story of high stakes politics—a story rich with contextual factors and as fascinating as the time the policy was formulated. As four very different environmental programs unfold—asbestos (updated to include the fallout from the World Trade Center), drinking water, radon, and surface coal mining—Scheberle demonstrates how programs evolve differently, with individual political, economic, logistical, and technical constraints. The policy implementation framework developed for the book provides the lens through which to compare environmental laws. Federalism and Environmental Policy goes beyond the contents of policy to explore the complex web of federal-state working relationships and their effect on the implementation of policy. It is unique in how it portrays the nuts-and-bolts, the extent to which the state and federal offices work together effectively—or not. Examining working relationships within the context of program implementation and across four different environmental programs offers a unique perspective on why environmental laws sometimes go awry.
