This book provides a comprehensive treatment of the rapidly changing world of Web-based business technologies and their often-disruptive innovations. The history of the Web is a short one. Indeed many college graduates today were not even born when the Web first emerged. It is therefore an opportune time to view the Web as having reached the point of graduation. The Web has led to new ways in which businesses connect and operate, and how individuals communicate and socialize; related technologies include cloud computing, social commerce, crowd sourcing, and the Internet of Things, to name but a few. These developments, including their technological foundations and business impacts, are at the heart of the book. It contextualizes these topics by providing a brief history of the World Wide Web, both in terms of the technological evolution and its resultant business impacts.The book was written for a broad audience, including technology managers and students in higher education. It is also intended as a guide for people who grew up with a background in business administration or engineering or a related area but who, in the course of their career paths, have reached a point where IT-related decisions have become their daily business, e.g., in digital transformation. The book describes the most important Web technologies and related business applications, and especially focuses on the business implications of these technologies. As such, it offers a solid technology- and business-focused view on the impact of the Web, and balances rules and approaches for strategy development and decision making with a certain technical understanding of what goes on “behind the scenes.”

Diese Theorie-Einführung hat konsequent praktische Anwendungen im Blick. Seien es Workflow-Systeme, Web Services, Verschlüsselung von Informationen, Authentifizierungsprotokolle oder selbstfahrende Autos – all diese Technologien haben enge Bezüge zu den theoretischen Grundlagen der Informatik. So trägt das Buch dazu bei, dass Studierende die Grundlagen der Theoretischen Informatik nicht nur verstehen, sondern auch anwenden können, um effektiv und produktiv an informationstechnischen Problemlösungen mitwirken zu können. Wegen seiner speziellen inhaltlichen und didaktischen Qualität ist das Buch neben dem Einsatz in der Lehre auch für das Selbststudium geeignet.

After a brief introduction to the topic of business process modeling, the book offers a quick-start into model-based business process engineering. After that, the foundations of the modeling languages used are conveyed. Meaningful examples are in the foreground - each of the underlying formalisms is treated only as far as needed. Next the Horus Method is described in detail. The book defines a sequence of activities which finally leads to the creation of a complete business process model. The Horus Method, incidentally, is not bound to the use of the Horus software tools. It can be used with other tools or, if necessary, be used even without tool support. Important application fields of business process engineering are described, where the spectrum ranges from business process reengineering to the development and implementation of information systems. The book concludes with an outlook on the future of business process engineering and highlights current research activities in the area.

Dieses Buch gibt eine umfassende und systematische Einfuhrung in die grundlegenden Konzepte von Datenbanken und Datenbanksystemen, behandelt die im Kontext objekt-relationaler Datenbanken relevanten Themen wie XML, XQuery und SQL und erlautert die Datenintegration uber Architekturkonzepte, Data Warehouses und OLAP sowie Data Mining. Es schliessen sich Datenbanksystemtechniken und ein Einblick in neuere Entwicklungen an."

The emergence of Web 2.0 is provoking challenging questions for developers: What products and services can our company provide to customers and employees using Rich Internet Applications, mash-ups, Web feeds or Ajax? Which business models are appropriate and how do we implement them? What are best practices and how do we apply them? If you need answers to these and related questions, you need Unleashing Web 2.0—a comprehensive and reliable resource that guides you into the emerging and unstructured landscape that is Web 2.0. Gottfried Vossen is a professor of Information Systems and Computer Science at the University of Muenster in Germany. He is the European Editor-in-Chief of Elsevier’s Information Systems—An International Journal. Stephan Hagemann is a PhD. Student in Gottfried’s research group focused on Web technologies.

Das erfolgreiche Standard-Lehrbuch zu den Grundbausteinen und den wichtigsten Architekturprinzipien heutiger Rechner. Das Buch beschreibt konsequent die logischen Aspekte und diskutiert technologische Fragen. Besonderen Stellenwert haben erlauternde und weiterfuhrende Beispiele und Ubungen. Uber das Internet ist ein Foliensatz zur Vorlesungsvorbereitung abrufbar.

Transactional Information Systems is the long-awaited, comprehensive work from leading scientists in the transaction processing field. Weikum and Vossen begin with a broad look at the role of transactional technology in today's economic and scientific endeavors, then delve into critical issues faced by all practitioners, presenting today's most effective techniques for controlling concurrent access by multiple clients, recovering from system failures, and coordinating distributed transactions.The authors emphasize formal models that are easily applied across fields, that promise to remain valid as current technologies evolve, and that lend themselves to generalization and extension in the development of new classes of network-centric, functionally rich applications. This book's purpose and achievement is the presentation of the foundations of transactional systems as well as the practical aspects of the field what will help you meet today's challenges.
