The Composable Enterprise: Agile, Flexible, Innovative
The benefits of digitalisation do not lie in the use of new technologies for existing processes, but in organisational changes and new business models. The book highlights the composable enterprise as the guiding principle for successful digital transformation and associated cost reductions and revenue increases. What does it mean? A composable enterprise is organised in a decentralised process-oriented way. This allows the enterprise to react quickly to new situations, develop or change processes and business models. The information systems are based on platform architectures. A paradigm shift to monolithic applications.Sector concepts for industry, consulting and universities show how organisation and application architectures interlock in the composable enterprise.The reader receives inspiration, a foundation and a compass for the digital transformation of a company to the composable enterprise.PROF. DR. DR. H.C. MULT. AUGUST-WILHELM SCHEER is one of the most influential figures and entrepreneurs in German computing. The ARIS method he developed for enterprise architecture and process management is used internationally.His books on business informatics have been highly influential and have been translated into several languages. His research focuses on information, innovation and business process management. In addition, Scheer is the publisher of the trade journal IM+io.He has founded several successful IT companies. He has been the sole shareholder of IDS Scheer Holding GmbH since 2010. The company network with over 1,300 employees includes the larger companies Scheer GmbH, imc AG and Scheer PAS GmbH.

From 2007 to 2011, he was President of Bitkom e. V. As an IT innovator and entrepreneur, he also works as an independent political consultant.Scheer is also an experienced and respected jazz baritone saxophonist and promotes culture and science with the help of the August-Wilhelm Scheer Foundation for Science and Art, which he founded in 2001. He is the holder of numerous national and international accolades. In 2017, he was inducted into the Hall of Fame of German Research.His interpretation of the composable enterprise is his vision for designing future-oriented digitised companies, one which he also implements in his own companies.
AI Applications to Communications and Information Technologies
AI APPLICATIONS TO COMMUNICATIONS AND INFORMATION TECHNOLOGIESAPPLY THE TECHNOLOGY OF THE FUTURE TO NETWORKING AND COMMUNICATIONS.Artificial intelligence, which enables computers or computer-controlled systems to perform tasks which ordinarily require human-like intelligence and decision-making, has revolutionized computing and digital industries like few other developments in recent history. Tools like artificial neural networks, large language models, and deep learning have quickly become integral aspects of modern life. With research and development into AI technologies proceeding at lightning speeds, the potential applications of these new technologies are all but limitless. AI Applications to Communications and Information Technologies offers a cutting-edge introduction to AI applications in one particular set of disciplines. Beginning with an overview of foundational concepts in AI, it then moves through numerous possible extensions of this technology into networking and telecommunications. The result is an essential introduction for researchers and for technology undergrad/grad student alike. AI Applications to Communications and Information Technologies readers will also find:* In-depth analysis of both current and evolving applications* Detailed discussion of topics including generative AI, chatbots, automatic speech recognition, image classification and recognition, IoT, smart buildings, network management, network security, and more* An authorial team with immense experience in both research and industryAI Applications to Communications and Information Technologies is ideal for researchers, industry observers, investors, and advanced students of network communications and related fields.

Self-Service BI & Analytics
Self-Service BI & Analytics. Planung, Implementierung und Organisation. November 2023.Self-Service im BI- und Analytics-Kontext bedeutet, dass BI-Anwender selbst aktiv werden, um auf bestimmte Daten und Informationsprodukte zuzugreifen. Dabei hängt die Möglichkeit des Self-Service von Umgebungsfaktoren ab, nicht von einzelnen Werkzeugen. Um die Daten nutzen zu können, ist Datenkompetenz bei den Beteiligten erforderlich. Self-Service ist somit als strategischer Prozess zu verstehen, der als Teil der Datenstrategie immer der Unternehmensstrategie folgt und eine Kultur der Transparenz und offenen Kommunikation erfordert.Dieses Buch bietet eine umfassende Einführung in die grundlegenden Konzepte von Self-Service BI & Analytics. Es beschreibt die derzeit gängigen Ansätze mit Fokus auf die Konzeption und Governance von Self-Service. Darüber hinaus werden Lösungen für konkrete Anwendungsfälle vorgestellt. Im Einzelnen werden behandelt:Planung von Self-Service: Was ist vor der Einführung von Self-Service im Kontext einer gesamtheitlichen Datenstrategie, der Organisation und der Unternehmensarchitektur zu beachten? Welche Governance-Anforderungen müssen berücksichtigt werden?Implementierung von Self-Service: Die Entwicklung und der Betrieb von Self-Service-Lösungen werden ebenso aufgezeigt wie die Positionierung gegenüber einer Schatten-IT und die Vermeidung von technischen Schulden.Organisation von Self-Service: BI-Communitys, die Mitarbeiterausbildung und die Etablierung einer Self-Service-Kultur im Unternehmen spielen hier eine wichtige Rolle.Das Buch liefert wertvolle Einblicke und hilfreiche Anregungen für die erfolgreiche Einführung und Realisierung von Self-Service-Initiativen in der Unternehmenspraxis.Michael Kalke implementiert BI-Lösungen seit mehr als zehn Jahren. Zurzeit arbeitet er für die Vaillant Group und etabliert u.a. Self-Service BI.Artur König verantwortet bei der reportingimpulse GmbH die ganzheitliche Umsetzung von Datenprodukten von der Datenquelle bis zum fertigen Datenprodukt im Microsoft-Umfeld. Philipp Baron Freytag von Loringhoven ist ein versierter Marketingexperte und Datenanalyst, der sich seit mehr als 15 Jahren auf die Kombination von Daten, Marketing und Technologie spezialisiert hat.Lars Schreiber arbeitet als Abteilungsleiter für Business Intelligence Services in der Global IT der Pepperl + Fuchs SE. Dr. Thomas Zachrau ist seit über 30 Jahren leidenschaftlich im Bereich Analytics unterwegs. Die Analytik der kundenzentrierten Prozesse liegt ihm besonders am Herzen.Leseprobe (PDF-Link)
Building Your Own JavaScript Framework
JavaScript frameworks play an essential role in web application development; however, no single framework works perfectly for all projects. This book will help you understand existing projects, design new software architecture, and maintain projects as they grow. You’ll go through software architecture principles with JavaScript, along with a guided example of structuring your project and maintenance guidance.This book covers framework planning aspects, enabling you to identify key stakeholders, understand JavaScript API design, and leverage complex abstraction. The second part of the book takes a practical programming approach to building your own framework by showing you how to structure modules and interfaces. As you advance, you’ll discover how to develop data-binding components, work with JavaScript APIs, and much more. While writing a framework is half the job, continuing to develop it requires effort from everyone involved. The concluding chapters help to achieve this by teaching you the crucial aspects of software maintenance and highlighting the constants of framework development.By the end of this book, you’ll have gained a clear understanding of the JavaScript framework landscape, along with the ability to build frameworks for your use cases.

Fundamentals of Trace and Log Analysis
This book will help you analyze traces and logs from different software environments and communicate analysis results using a pattern language that covers everything from a small debugging log to a distributed trace with billions of messages from hundreds of computers, thousands of software components, threads, and processes.The book begins with the basic terminology of operating systems and programming, the foundation for understanding trace and log analysis. It then talks about patterns that help describe problems from a user’s view and patterns for errors and failures. Then, the book covers a range of trace patterns that group messages, and explores how logs depict software activities. It even examines specific message patterns and how they connect in a single trace. Moving forward, you’ll review patterns for multiple traces and logs and how to evaluate them.
