by Olaf MuschEine praxisnahe Beschreibung der Software Design Patterns, wie sie im 1994 erschienen Buch „Design Patterns – Elements of Reusable Object-Oriented Software“ der Autorengruppe Gamma, Helm, Johnson und Vlissides (auch genannt „Gang of Four“, kurz GoF, also „Viererbande“) Erwähnung finden.Alle Muster werden anhand von Beispielen detailliert erläutert und auch kritisch gewürdigt. Darüber hinaus werden Entwurfsprinzipien der objektorientierten Programmierung beschrieben und berücksichtigt. Alle Beispiele sind ausführlich im Quellcode kommentiert und unter Java 16 lauffähig. Teilweise werden auch neuere Features von Java bis einschließlich Version 16 erläutert und verwendet.
Design Patterns with Java: An Introduction
by Olaf MuschA practical description of the software design patterns as they are mentioned in the 1994 book "Design Patterns - Elements of Reusable ObjectOriented Software" by the author group Gamma, Helm, Johnson and Vlissides (also called "Gang of Four", GoF for short). All patterns are explained in detail by means of examples and also critically appreciated. Furthermore, design principles of object-oriented programming are described and considered. All examples are commented in detail in the source code and are executable under Java 16. In part, newer features of Java up to and including version 16 are also explained and used.
Design Patterns: Elements of Reusable Object-Oriented Software
by Erich Gamma Richard Helm Ralph Johnson John VlissidesThis book assumes you are reasonably proficient in at least one object-oriented programming language, and you should have some experience in object-oriented design as well. It's a book of design patterns that describes simple and elegant solutions to specific problems in object-oriented software design. Design patterns capture solutions that have developed and evolved over time. Hence they aren't the designs people tend to generate initially. They reflect untold redesign and recoding as developers have struggled for greater reuse and flexibility in their software. Design patterns capture these solutions in a succinct and easily applied form.
Design Praxiology and Phenomenology: Understanding Ways of Knowing through Inventive Practices
by Beaumie Kim Lynde TanThis book offers insight into designerly ways of knowing from the perspectives of experts and professionals engaging in diverse forms of design in workplaces and other public domains. It also aids in the understanding of design practices from designers’ viewpoints via case studies. By pursuing a reflective inquiry in their design epistemology (designerly ways of knowing), design praxiology (practices of design), or design phenomenology (forms of designs), self-studies of design practices, and presenting studies of designs, the authors of this book demonstrate how they influence the people and the object of inquiry or design. The case studies presented in this book also illustrate how designers develop their expertise, and provides inspiration for the incorporation of design-thinking and practice in education.

Design Research in Information Systems
by Alan Hevner Samir ChatterjeeThe study of Information Systems (IS) design is an essential part of the education of IS students and professionals. The purpose of this book is to provide a thorough reference on Design Science Research (DSR), and it comes from two authors closely identified with DSR - Alan Hevner and Samir Chatterjee. As founders of the Design Science Research in Information Systems and Technology (DESRIST) annual conference, and as leading educators and researchers in the field, these authors, along with several invited contributors , are uniquely qualified to create this easy-to-read, easy-to-understand, and easy-to-apply text/reference. Suitable for graduate courses in IS, computer science, software engineering, engineering design and other design-oriented fields, it can be used as a core text or a reference for doctoral seminars in DSR. IS faculty and researchers will find much of value here as well. It requires no extensive background in design and can be appreciated by practitioners working in IS or technology design. Its 18 chapters are all individually referenced, and two appendices provide a reprint of the seminal 2004 MISQ paper by Hevner, March, Park, and Ram, as well as a list of exemplar papers in Design Science. The book provides a thorough introduction to DSR, a look at DSR in IS, examinations of DSR frameworks and design theory, and a look at the key principles of DSR in IS. Other chapters look at design for software-intensive systems, people and design, the past and present of software designs, evaluation methods, focus-group use, design creativity, and a design language for knowledge management systems. Later chapters explore integrating action research with design research, design science in management disciplines, a critical realist perspective of DSR in IS, a taxonomic look at design of emerging digital services, the dissemination of DSR, and, finally, a look at the future for DSR in IS.
Design Research on Learning and Thinking in Educational Settings: Enhancing Intellectual Growth and Functioning (Educational Psychology Series)
by David Yun DaiThe key question this book addresses is how to identify and create optimal conditions for the kind of learning and development that is especially important for effectively functioning in the 21st century. Taking a new approach to this long-debated issue, it looks at how a design research-based science of learning (with its practical models and related design research) can provide insights and integrated models of how human beings actually function and grow in the social dynamics of educational settings with all their affordances and constraints. More specifically: How can specific domains or subject matters be taught for broad intellectual development? How can technology be integrated in enhancing human functioning? How can the social organization of classroom learning be optimized to create social norms for promoting deep intellectual engagement and personal growth? Part I is concerned with broad conceptual and technical issues regarding cultivating intellectual potential, with a focus on how design research might fill in an important a niche in addressing these issues. Part II presents specific design work in terms of design principles, models, and prototypes.
Design Science Methodology for Information Systems and Software Engineering
by Roel J. WieringaThis book provides guidelines for practicing design science in the fields of information systems and software engineering research. A design process usually iterates over two activities: first designing an artifact that improves something for stakeholders and subsequently empirically investigating the performance of that artifact in its context. This "validation in context" is a key feature of the book - since an artifact is designed for a context, it should also be validated in this context. The book is divided into five parts. Part I discusses the fundamental nature of design science and its artifacts, as well as related design research questions and goals. Part II deals with the design cycle, i. e. the creation, design and validation of artifacts based on requirements and stakeholder goals. To elaborate this further, Part III presents the role of conceptual frameworks and theories in design science. Part IV continues with the empirical cycle to investigate artifacts in context, and presents the different elements of research problem analysis, research setup and data analysis. Finally, Part V deals with the practical application of the empirical cycle by presenting in detail various research methods, including observational case studies, case-based and sample-based experiments and technical action research. These main sections are complemented by two generic checklists, one for the design cycle and one for the empirical cycle. The book is written for students as well as academic and industrial researchers in software engineering or information systems. It provides guidelines on how to effectively structure research goals, how to analyze research problems concerning design goals and knowledge questions, how to validate artifact designs and how to empirically investigate artifacts in context - and finally how to present the results of the design cycle as a whole.
Design Science Research
by Aline Dresch Daniel Pacheco Lacerda José Antônio Valle AntunesConsolidating existing knowledge in Design Science, this book proposes a new research method to aid the exploration of design and problem solving within business, science and technology. It seeks to overcome a dichotomy that exists in the field between theory and practice to enable researches to find solutions to problems, rather than focusing on the explanation and exploration of the problems themselves. Currently, researches concentrate on to describing, exploring, explaining and predicting phenomena, and little attention is devoted to prescribing solutions. Herbert Simon proposes the need to develop a Science of the Artificial (Design Science), arguing that our reality is much more artificial than natural. However, the research conducted on the Design Science premises has so far been scattered and erratic in different fields of research, such as management, systems information and engineering. This book aims to address this issue by bringing these fields together and emphasising the need for solutions. This book provides a valuable resource to students and researchers of research methods, information systems, management and management science, and production and operations management.

Design Science Research. Cases (Progress in IS)
by Alan Hevner Jan Vom Brocke Alexander MaedcheDesign Science Research is a powerful paradigm enabling researchers to make important contributions to society and industry. Simply stated, the goal of DSR is to generate knowledge on how to find innovative solutions to important problems in the form of models, methods, constructs and instantiations. Over the past 20 years, the design science research (DSR) paradigm has developed into an established paradigm in Information Systems Research and it is of strong uptake in many other disciplines, including Management Science and Computer Science. This book provides a collection of twelve DSR cases, presented by experienced researchers in the field. It offers readers access to real-world DSR studies, together with the authors’ reflections on their research processes. These cases will support researchers who want to engage in DSR, and represent a valuable addition to existing introductions to DSR methods and processes. Readers will learn from the hands-on experiences of respected experts who have conducted extensive DSR in a range of application contexts.
Design Space Exploration in Robotics (Studies in Systems, Decision and Control #229)
by Frank EhlersThis book provides a foundation of the overall cycle from design and modelling to implementation and control of unmanned systems, exhibiting autonomy and instantiating self-organization amidst disturbances, also functioning in uncertain and dynamic environments. The underlying assumption of the research path taken is that unmanned systems exhibiting attributes of autonomy, autonomous functionality, and resilience have to be considered as technically engineered systems. Hence, validation, verification, certification, and acceptance testing have to be provided together with the product "robot capable of fulfilling a specific requirement." The key is to provide a mathematically sound “metric” to evaluate autonomy, autonomous functionality, and resilience, directly applicable to real complex engineering systems. This overarching approach, presented as a lecture script, is reaching out to provide an ethically aligned view on engineering, specifically aiming to support human's free will.
