Database research in the last decade has increasingly focused on providing support for non-standard applications. One important domain is representation and processing of spatial information, needed, e.g., in geographical information systems. Spatial data types provide a fundamental abstraction for modeling the structure of geometric entities, their relationships, properties and operations. This monograph is an extensive survey of this field and introduces a new, general, sophisticated framework for the formal definition and robust implementation of spatial data types.

This book explores the concept of a map as a fundamental data type. It defines maps at three levels. The first is an abstract level, in which mathematic concepts are leveraged to precisely explain maps and operational semantics. The second is at a discrete level, in which graph theory is used to create a data model with the goal of implementation in computer systems. Finally, maps are examined at an implementation level, in which the authors discuss the implementation of a fundamental map data type in database systems. The map data type presented in this book creates new mechanisms for the storage, analysis, and computation of map data objects in any field that represents data in a map form. The authors develop a model that includes a map data type capable of representing thematic and geometric attributes in a single data object. The book provides a complete example of mathematically defining a data type, ensuring closure properties of those operations, and then translating that type into a state that is suited for implementation in a particular context. The book is designed for researchers and professionals working in geography or computer science in a range of fields including navigation, reasoning, robotics, geospatial analysis, data management, and information retrieval.

Der Band dokumentiert die Beiträge der 2018 veranstalteten Tagung der Arbeitsgemeinschaft für germanistische Edition. Die Kategorie der Aufführung bzw. Performance hat in den Geistes- und Kulturwissenschaften in den letzten beiden Dezennien einen großen Wandel erfahren. Nicht nur rückte die Aufführung selbst zunehmend ins Zentrum der Betrachtung der performativen Künste, sondern mehr noch wurden auch die verschiedensten Textsorten auf ihre Performanz hin befragt. Das Verhältnis von 'Werk' und Aufführung ist dabei in den verschiedenen Disziplinen unterschiedlich gelagert: Während die Aufführung für einen musikalischen Text - und damit die Edition - gleichsam die 'raison d'être' bildet, stellt sich dieses Verhältnis für einen Dramentext (und dessen Edition) anders dar. Die hier versammelten Beiträge nehmen die unterschiedlichsten Formen von Aufführungstexten in den Blick und sind daher für Literatur-, Musik-, Kultur-, Theater-, Film- und Medienwissenschaftler gleichermaßen von Interesse.

The Seventh International Symposium on Spatial and Temporal Databases (SSTD 2001), held in Redondo Beach, CA, USA, July 12{15, 2001, brought together leading researchers and developers in the area of spatial, temporal, and spatio-temporal databases to discuss the state of the art in spatial and temporal data management and applications, and to understand the challenges and - search directions in the advancing area of data management for moving objects. The symposium served as a forum for disseminating research in spatial and temporal data management, and for maximizing the interchange of knowledge among researchers from the established spatial and temporal database com- nities. The exchange of research ideas and results not only contributes to the academic arena, but also bene ts the user and commercial communities. SSTD 2001 was the seventh in the series of symposia that started in Santa Barbara a dozen years ago and has since been held every two years, in Zurich, Singapore, Portland (Maine), Berlin, and Hong Kong. By 1999, the series had become well established as the premier international forum devoted solely to spatial database management, and it was decided to extend the scope of the series to also cover temporal database management. This extended scope was chosen due, in part, to the increasing importance of research that considers spatial and temporal aspects jointly.
