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.

Anniversary publication of the Belvedere The Belvedere in Vienna epitomizes the changes that have taken place over the course of three centuries in the concept of what constitutes a museum. Originally built by Prince Eugene of Savoy to enhance his prestige as a prince, under Maria Theresa, the Upper Belvedere became one of the world’s first public museums. The idea of presenting Austrian art in an international context, which in 1903 motivated the establishment of the Modern Gallery in the Lower Belvedere, remains the key objective of this world-famous cultural institution. In this critical homage, renowned authors explore enduring questions that transcend the different epochs, such as : What ordering concepts are evident in art presentation ? How contemporary were these presentations in an international context ? What kind of public were they aimed at ? Anniversary publication of the Österreichische Galerie Belvedere: a critical homage to a place of art with a diverse history spanning centuries Exhibition until January 7, 2024 With contributions from Johanna Aufreiter, Björn Blauensteiner, Brigitte Borchhardt-Birbaumer, Thomas DaCosta Kaufmann, Christiane Erharter, Nora Fischer, Anna Frasca-Rath, Antoinette Friedenthal, Martin Fritz, Thomas W.

In the late 1700s, as the events of the French Revolution roiled France, London displaced Paris as the primary hub of international art sales. Within a few decades, a robust and sophisticated art market flourished in London. 'London and the Emergence of a European Art Market, 1780-1820' explores the commercial milieu of art sales and collecting at this turning point. In this collection of essays, twenty-one scholars employ methods ranging from traditional art historical and provenance studies to statistical and economic analysis; they provide overviews, case studies and empirical reevaluations of artists, collectors, patrons, agents and dealers, institutions, sales and practices. Drawing from pioneering digital resources-notably the Getty Provenance Index-as well as archival materials, such as trade directories, correspondence, stock books and inventories, auction catalogs and exhibition reviews, these scholars identify broad trends, reevaluate previous misunderstandings and consider overlooked commercial contexts to illuminate artistic taste. From individual case studies to econometric overviews, this volume is groundbreaking for its diverse methodological range that illuminates artistic taste and flourishing art commerce at the turn of the nineteenth century.
