Data-intensive systems are software applications that process and generate Big Data. Data-intensive systems support the use of large amounts of data strategically and efficiently to provide intelligence. For example, examining industrial sensor data or business process data can enhance production, guide proactive improvements of development processes, or optimize supply chain systems. Designing data-intensive software systems is difficult because distribution of knowledge across stakeholders creates a symmetry of ignorance, because a shared vision of the future requires the development of new knowledge that extends and synthesizes existing knowledge. Knowledge Management in the Development of Data-Intensive Systems addresses new challenges arising from knowledge management in the development of data-intensive software systems. These challenges concern requirements, architectural design, detailed design, implementation and maintenance. The book covers the current state and future directions of knowledge management in development of data-intensive software systems. The book features both academic and industrial contributions which discuss the role software engineering can play for addressing challenges that confront developing, maintaining and evolving systems;data-intensive software systems of cloud and mobile services; and the scalability requirements they imply. The book features software engineering approaches that can efficiently deal with　data-intensive systems as well as applications and use cases benefiting from data-intensive systems. Providing a comprehensive reference on the notion of data-intensive systems from a technical and non-technical perspective, the book focuses uniquely on software engineering and knowledge management in the design and maintenance of data-intensive systems. The book covers constructing, deploying, and maintaining high quality software products and software engineering in and for dynamic and flexible environments. This book provides a holistic guide for those who need to understand the impact of variability on all aspects of the software life cycle.

A revolutionary concept-based approach to thinking about, designing, and interacting with softwareAs our dependence on technology increases, the design of software matters more than ever before. Why then is so much software flawed? Why hasn't there been a systematic and scalable way to create software that is easy to use, robust, and secure?Examining these issues in depth, The Essence of Software introduces a theory of software design that gives new answers to old questions. Daniel Jackson explains that a software system should be viewed as a collection of interacting concepts, breaking the functionality into manageable parts and providing a new framework for thinking about design. Through this radical and original perspective, Jackson lays out a practical and coherent path, accessible to anyone—from strategist and marketer to UX designer, architect, or programmer—for making software that is empowering, dependable, and a delight to use.Jackson explores every aspect of concepts—what they are and aren't, how to identify them, how to define them, and more—and offers prescriptive principles and practical tips that can be applied cost-effectively in a wide range of domains. He applies these ideas to contemporary software designs, drawing examples from leading software manufacturers such as Adobe, Apple, Dropbox, Facebook, Google, Microsoft, Twitter, and others. Jackson shows how concepts let designers preserve and reuse design knowledge, rather than starting from scratch in every project.An argument against the status quo and a guide to improvement for both working designers and novices to the field, The Essence of Software brings a fresh approach to software and its creation.

Writing and running software is now as much a part of science as telescopes and test tubes, but most researchers are never taught how to do either well. As a result, it takes them longer to accomplish simple tasks than it should, and it is harder for them to share their work with others than it needs to be.This book introduces the concepts, tools, and skills that researchers need to get more done in less time and with less pain. Based on the practical experiences of its authors, who collectively have spent several decades teaching software skills to scientists, it covers everything graduate-level researchers need to automate their workflows, collaborate with colleagues, ensure that their results are trustworthy, and publish what they have built so that others can build on it. The book assumes only a basic knowledge of Python as a starting point, and shows readers how it, the Unix shell, Git, Make, and related tools can give them more time to focus on the research they actually want to do.Research Software Engineering with Python can be used as the main text in a one-semester course or for self-guided study. A running example shows how to organize a small research project step by step; over a hundred exercises give readers a chance to practice these skills themselves, while a glossary defining over two hundred terms will help readers find their way through the terminology. All of the material can be re-used under a Creative Commons license, and all royalties from sales of the book will be donated to The Carpentries, an organization that teaches foundational coding and data science skills to researchers worldwide.

If you want to understand what Agile is and how it came to be, this is the book for you.” –Grady Booch “Bob's frustration colors every sentence of Clean Agile, but it's a justified frustration. What is in the world of Agile development is nothing compared to what could be. This book is Bob's perspective on what to focus on to get to that ‘what could be.'And he's been there, so it's worth listening.” –Kent Beck “It's good to read Uncle Bob's take on Agile. Whether just beginning, or a seasoned Agilista, you would do well to read this book. I agree with almost all of it. It's just some of the parts make me realize my own shortcomings, dammit. It made me double-check our code coverage (85.09%).” –Jon Kern Nearly twenty years after the Agile Manifesto was first presented, the legendary Robert C. Martin (“Uncle Bob”) reintroduces Agile values and principles for a new generation–programmers and nonprogrammers alike. Martin, author of Clean Code and other highly influential software development guides, was there at Agile's founding. Now, in Clean Agile: Back to Basics, he strips away misunderstandings and distractions that over the years have made it harder to use Agile than was originally intended. Martin describes what Agile is in no uncertain terms: a small discipline that helps small teams manage small projects... with huge implications because every big project is comprised of many small projects. Drawing on his fifty years'experience with projects of every conceivable type, he shows how Agile can help you bring true professionalism to software development. Get back to the basics–what Agile is, was, and should always be Understand the origins, and proper practice, of SCRUM Master essential business-facing Agile practices, from small releases and acceptance tests to whole-team communication Explore Agile team members'relationships with each other, and with their product Rediscover indispensable Agile technical practices: TDD, refactoring, simple design, and pair programming Understand the central roles values and craftsmanship play in your Agile team's success If you want Agile's true benefits, there are no shortcuts: You need to do Agile right. Clean Agile: Back to Basics will show you how, whether you're a developer, tester, manager, project manager, or customer.

Der Erfolg der Digitalisierung hängt nicht nur vom richtigen Mindset des Top-Managements ab. Viele Unternehmen kämpfen mit einem viel handfesteren Thema: der Verfügbarkeit von qualifizierten und motivierten IT-Experten. Der Markt ist leergefegt, die Gehälter steigen immer weiter. Und mit der Rekrutierung x-beliebiger IT-Experten ist das Problem noch lange nicht gelöst: Studien zeigen den massiven Produktivitätsunterschied zwischen guten und weniger guten Entwicklern. Im War for IT-Talents gewinnen nicht die Unternehmen, die die besten Gehälter zahlen, sondern jene, die ein echtes Verständnis dafür haben, wie die Zielgruppe tickt. Die Autoren erklären, was ein Softwareentwickler eigentlich macht, was ihn beschäftigt, wodurch er sich anerkannt fühlt und worauf man beim Employer Branding, Recruiting und in der Mitarbeiterführung achten muss. Das Ziel: die richtigen Experten gewinnen, motivieren und langfristig binden. Inhalte: - Was machen Software Developer eigentlich den ganzen Tag? - Wie geht man mit Software Developern am besten um? Employer Branding, Rekrutierung, Auswahl, Motivation - Kurz-Interviews mit HR-Verantwortlichen und Managern in erfolgreichen Tech-Firmen, IT-Startups etc. - Aus dem Innenleben eines Software Developers: Wie nimmt er seine Führung wahr? Für welche Innovationen und Arbeitsformen brennt er? Mit welchen Vorurteilen kann er gar nichts anfangen?

Even amazing products can be let down by poor user interfaces. It is the job of front-end developers to make software products and websites engaging and attractive for users. This book covers the role of front-end developer in terms of typical responsibilities, required skills and relevant tools, methods and techniques. Career progression for front-end developers is also discussed.

Efficiency is a crucial concern across computing systems, from the edge to the cloud. Paradoxically, even as the latencies of bottleneck components such as storage and networks have dropped by up to four orders of magnitude, software path lengths have progressively increased due to overhead from the very frameworks that have revolutionized the pace of information technology. Such overhead can be severe enough to overshadow the benefits from switching to new technologies like persistent memory and low latency interconnects. Resource Proportional Software Design for Emerging Systems introduces resource proportional design (RPD) as a principled approach to software component and system development that counters the overhead of deeply layered code without removing flexibility or ease of development. RPD makes resource consumption proportional to situational utility by adapting to diverse emerging needs and technology systems evolution. Highlights: Analysis of run-time bloat in deep software stacks, an under-explored source of power-performance wastage in IT systems Qualitative and quantitative treatment of key dimensions of resource proportionality Code features: Unify and broaden supported but optional features without losing efficiency Technology and systems evolution: Design software to adapt with changing trade-offs as technology evolves Data processing: Design systems to predict which subsets of data processed by an (analytics or ML) application are likely to be useful System wide trade-offs: Address interacting local and global considerations throughout software stacks and hardware including cross-layer co-design involving code, data and systems dimensions, and non-functional requirements such as security and fault tolerance Written from a systems perspective to explore RPD principles, best practices, models and tools in the context of emerging technologies and applications This book is primarily geared towards practitioners with some advanced topics for researchers. The principles shared in the book are expected to be useful for programmers, engineers and researchers interested in ensuring software and systems are optimized for existing and next generation technologies. The authors are from both industry (Bhattacharya and Voigt) and academic (Gopinath) backgrounds.

This textbook examines database systems from the viewpoint of a software developer. This perspective makes it possible to investigate why database systems are the way they are. It is of course important to be able to write queries, but it is equally important to know how they are processed. We e.g. don't want to just use JDBC; we also want to know why the API contains the classes and methods that it does. We need a sense of how hard is it to write a disk cache or logging facility. And what exactly is a database driver, anyway?The first two chapters provide a brief overview of database systems and their use. Chapter 1 discusses the purpose and features of a database system and introduces the Derby and SimpleDB systems. Chapter 2 explains how to write a database application using Java. It presents the basics of JDBC, which is the fundamental API for Java programs that interact with a database. In turn, Chapters 3-11 examine the internals of a typical database engine. Each chapter covers a different database component, starting with the lowest level of abstraction (the disk and file manager) and ending with the highest (the JDBC client interface); further, the respective chapter explains the main issues concerning the component, and considers possible design decisions. As a result, the reader can see exactly what services each component provides and how it interacts with the other components in the system. By the end of this part, s/he will have witnessed the gradual development of a simple but completely functional system. The remaining four chapters then focus on efficient query processing, and focus on the sophisticated techniques and algorithms that can replace the simple design choices described earlier. Topics include indexing, sorting, intelligent buffer usage, and query optimization.This text is intended for upper-level undergraduate or beginning graduate courses in Computer Science. It assumes that the reader is comfortable with basic Java programming; advanced Java concepts (such as RMI and JDBC) are fully explained in the text. The respective chapters are complemented by “end-of-chapter readings” that discuss interesting ideas and research directions that went unmentioned in the text, and provide references to relevant web pages, research articles, reference manuals, and books. Conceptual and programming exercises are also included at the end of each chapter. Students can apply their conceptual knowledge by examining the SimpleDB (a simple but fully functional database system created by the author and provided online) code and modifying it.

Standardwerk zur SoftwarearchitekturSchließt die Lücke zwischen Softwarearchitektur und Implementierung der Codebasis - Einfache und übersichtliche Strukturierung aller wichtigen Grundkonzepte im Bereich der Softwarearchitektur, die die typischen Fehler in der Softwarearchitektur von großen Softwaresysteme aufzeigen und sinnvolle Lösungen vermitteln. - Mit über 200 farbigen Bildern aus real existierenden Softwaresystemen und etlichen Fallbeispielen Zu Beginn eines Projekts erarbeiten die Architekten und das Entwicklungsteam eine zugeschnittene Architekturblaupause für die anstehende Entwicklung. Aber während der Implementierung weicht das Team häufig ungewollt von dieser Vorgabe ab. Die Folge davon: Die Architektur des Systems erodiert, die Komplexität nimmt zu, und es werden technische Schulden aufgebaut. Wartung und Erweiterung der Software werden immer aufwendiger. In diesem Buch zeigt die Autorin, welche Fehler in Softwareprojekten bei der Umsetzung der Architektur vermieden werden sollten und welche Prinzipien eingehalten werden müssen, um langlebige Architekturen zu entwerfen oder bei bestehenden Systemen zu langlebigen Architekturen zu gelangen. Sie geht auf Muster in Softwarearchitekturen und Mustersprachen ein, erläutert verschiedene Architekturstile und zeigt, welche Vorgaben letztlich zu Architekturen führen, die für Entwickler noch gut durchschaubar sind. Mit über 200 farbigen Bildern aus real existierenden Softwaresystemen und etlichen Fallbeispielen werden schlechte und gute Lösungen verständlich und nachvollziehbar dargestellt. Empfehlungen und vielfältige Hinweise aus Praxisprojekten erlauben dem Leser einen direkten Transfer zu seiner täglichen Arbeit. Die 3. Auflage wurde in einzelnen Aspekten überarbeitet und insbesondere bei den Themen Domain-Driven Design und Microservices ergänzt. Neu aufgenommen wurden die Analyse von TypeScript-Systemen sowie Clean-, Onion- und hexagonale Architekturen.
