This book is dedicated to Professor Martin Wirsing on the occasion of his emeritation from Ludwig-Maximilians-Universität in Munich, Germany. The volume is a reflection, with gratitude and admiration, on Professor Wirsing’s life highly creative, remarkably fruitful and intellectually generous life. It also gives a snapshot of the research ideas that in many cases have been deeply influenced by Professor Wirsing’s work. The book consists of six sections. The first section contains personal remembrances and expressions of gratitude from friends of Professor Wirsing. The remaining five sections consist of groups of scientific papers written by colleagues and collaborators of Professor Wirsing, which have been grouped and ordered according to his scientific evolution. More specifically, the papers are concerned with logical and algebraic foundations; algebraic specifications, institutions and rewriting; foundations of software engineering; service oriented systems; and adaptive and autonomic systems.

This is a practical guide for software developers, and different than other software architecture books. Here's why: It teaches risk-driven architecting. There is no need for meticulous designs when risks are small, nor any excuse for sloppy designs when risks threaten your success. This book describes a way to do just enough architecture. It avoids the one-size-fits-all process tar pit with advice on how to tune your design effort based on the risks you face. It democratizes architecture. This book seeks to make architecture relevant to all software developers. Developers need to understand how to use constraints as guiderails that ensure desired outcomes, and how seemingly small changes can affect a system's properties. It cultivates declarative knowledge. There is a difference between being able to hit a ball and knowing why you are able to hit it, what psychologists refer to as procedural knowledge versus declarative knowledge. This book will make you more aware of what you have been doing and provide names for the concepts. It emphasizes the engineering. This book focuses on the technical parts of software development and what developers do to ensure the system works not job titles or processes. It shows you how to build models and analyze architectures so that you can make principled design tradeoffs. It describes the techniques software designers use to reason about medium to large sized problems and points out where you can learn specialized techniques in more detail. It provides practical advice. Software design decisions influence the architecture and vice versa. The approach in this book embraces drill-down/pop-up behavior by describing models that have various levels of abstraction, from architecture to data structure design.

Martin Fowler is a consultant specializing in object-oriented analysis and design. This book presents and discusses a number of object models derived from various problem domains. All patterns and models presented have been derived from the author's own consulting work and are based on real business cases.

In the quest for quality, software developers have long focused on improving the internal architecture of their products. Larry L. Constantine--who originally created structured design to effect such improvement--now joins with well-known consultant Lucy A. D. Lockwood to turn the focus of software development to the external architecture. In this book, they present the models and methods of a revolutionary approach to software that will help programmers deliver more usable software--software that will enable users to accomplish their tasks with greater ease and efficiency. Recognizing usability as the key to successful software, Constantine and Lockwood provide concrete tools and techniques that programmers can employ to meet that end. Much more than just another set of rules for good user-interface design, this book guides readers through a systematic software development process. This process, called usage-centered design, weaves together two major threads in software development methods: use cases (also used with UML) and essential modeling. With numerous examples and case studies of both conventional and specialized software applications, the authors illustrate what has been shown in practice to work and what has proved to be of greatest practical value. Highlights Presents a streamlined process for developing highly usable software Describes practical methods and models successfully implemented in industry Complements modern development practices, including the Unified Process and other object-oriented software engineering approaches

This brilliant textbook explains in detail the principles of conceptual modeling independently from particular methods and languages and shows how to apply them in real-world projects. The author covers all aspects of the engineering process from structural modeling over behavioral modeling to meta-modeling, and completes the presentation with an extensive case study based on the osCommerce system. Written for computer science students in classes on information systems modeling as well as for professionals feeling the need to formalize their experiences or to update their knowledge, Olivé delivers here a comprehensive treatment of all aspects of the modeling process. His book is complemented by lots of exercises and additional online teaching material.

Business rules management system (BRMS) is a software tools that work alongside enterprise IT applications. It enables enterprises to automate decision-making processes typically consisting of separate business rules authoring and rules execution applications. This proposed title brings together the following key ideas in modern enterprise system development best practice. The need for service-oriented architecture (SOA). How the former depends on component-based development (CBD). Database-centred approaches to business rules (inc. GUIDES). Knowledge-based approaches to business rules. Using patterns to design and develop business rules management systems Ian Graham is an industry consultant with over 20 years. He is recognized internationally as an authority on business modelling, object-oriented software development methods and expert systems. He has a significant public presence, being associated with both UK and international professional organizations, and is frequently quoted in the IT and financial press.

This book is written for students and developers whowish to master the essential skills and techniques in applying the UML forsoftware development. The reader will learn object-oriented analysis, design andimplementation using appropriate UML models, process, techniques and tool.Accompanying the book is the Community Edition of Visual Pradigm for UML (VP-UML),an award-winning CASE tool, which allows the reader to put the theories learnedinto practice immediately.The authors propose a novel framework for modeling and analysis called the ViewAlignment Techniques (VAT) that helps software developers create developmentmethods. The Activity Analysis Approach (A3), which is particularlysuited for the development of interaction-intensive systems, is described. Theseconcepts have been well proven, as they were followed closely in the developmentof the VP-UML CASE tool.Three chapters in this book describe structural, use case and dynamic modelingand analysis techniques, together with practical tricks and tips that have beengained by the authors from many years of experience. Each of these threechapters includes a mini-case study which illustrates the unique "fromdiagram to code" concept in software development. In the final chapter, amajor case study is included to help the reader reinforce the theories learnedin previous chapters using VP-UML.The key areas in object-oriented technology covered in the book include:Requirements modeling using cases:Identifying, capturing and elaborating requirements.Domain analysis for object identification:Building structural models for objects and their attributes andrelationships.Dynamic analysis and design: Building dynamicmodels, refining structural models and making design decisions.Implementation: Translating UML models intocodes and implementations.Method creation and the framework of ViewAlignment Techniques: Choosing the right UML models and customizing theanalysis and design process.A case study: Showing how the ActivityAnalysis Approach is put into practice, using VP-UML.Additional material can be found at http://www.mcgraw-hill.com.sg/olc/tsang.Instructors will benefit from useful tools such as PowerPoint slides (passwordprotected) and answers to exercises (password protected), while students canobtain source code and additional exercises and test questions.Visual Paradigm for UML, the CASE tool used extensively in this book, washonored in the 15th Annual Software Development Magazine Jolt Productivity Awardin the Design and Analysis Tools category in March 2004.
