This book constitutes the refereed proceedings of the 6th International Conference on Theory and Practice of Model Transformations, ICMT 2013, held in Budapest, Hungary, in June 2013. The 13 full papers and 5 tool and application demonstrations were carefully selected from 58 submissions. The papers are grouped in topical sections which focus on new programming models, tools and applications, evolution and synchronization, transformation engineering, and testing.

This book constitutes the refereed proceedings of the 9th International Conference on Service-Oriented Computing, ICSOC 2011, held in Paphos, Cyprus, in December 2011. The 54 revised papers presented were carefully reviewed and selected from 184 submissions. The papers are organized in topical sections on business process modeling, quality of service, formal methods, XaaS computing, service discovery, service security and trust, service runtime infrastructures and service applications.

This textbook mainly addresses beginners and readers with a basic knowledge of object-oriented programming languages like Java or C#, but with little or no modeling or software engineering experience - thus reflecting the majority of students in introductory courses at universities. Using UML, it introduces basic modeling concepts in a highly precise manner, while refraining from the interpretation of rare special cases. After a brief explanation of why modeling is an indispensable part of software development, the authors introduce the individual diagram types of UML (the class and object diagram, the sequence diagram, the state machine diagram, the activity diagram, and the use case diagram), as well as their interrelationships, in a step-by-step manner. The topics covered include not only the syntax and the semantics of the individual language elements, but also pragmatic aspects, i.e., how to use them wisely at various stages in the software development process. To this end, the work is complemented with examples that were carefully selected for their educational and illustrative value. Overall, the book provides a solid foundation and deeper understanding of the most important object-oriented modeling concepts and their application in software development. An additional website offers a complete set of slides to aid in teaching the contents of the book, exercises and further e-learning material.

This book constitutes the refereed proceedings of the 39th International Conference on Conceptual Modeling, ER 2020, which was supposed to be held in Vienna, Austria, in November 2020, but the conference was held virtually due to the COVID-19 pandemic. The 28 full and 16 short papers were carefully reviewed and selected from 143 submissions. This events covers a wide range of topics, and the papers are organized in the following sessions: foundations of conceptual modeling; process mining and conceptual modeling; conceptual modeling of business rules and processes; modeling chatbots, narratives and natural language; ontology and conceptual modeling; applications of conceptual modeling; schema design, evolution, NoSQL; empirical studies of conceptual modeling; networks, graphs and conceptual modeling; and conceptual modeling of complex and data-rich systems.

Das Buch gibt einen hochaktuellen Einstieg mit Tiefgang in die objektorientierte Entwicklung von Informationssystemen. Das Ziel des Buches ist es, unabhAngig von einer konkreten Methode die grundlegenden Konzepte, Darstellungsmittel, Verfahrensschritte und Techniken zur objektorientierten Modellierung von Informationssystemen aufzuzeigen. Der Leser lernt objektorientierte Modellierungskonzepte und Techniken zu verstehen, eine aufgabenspezifische Bewertung einer konkreten Methode durchzufA1/4hren und gegebenenfalls fA1/4r seine eigenen Probleme einzusetzen. Zahlreiche Beispiele veranschaulichen die unmittelbare Einsetzbarkeit des vermittelten Wissens. Das Buch bietet darA1/4ber hinaus eine aktuelle Orientierungshilfe zum VerstAndnis der umfangreichen objektorientierten Methodenlandschaft.
