Data management systems play the most crucial role in building large application s- tems. Since modern applications are no longer single monolithic software blocks but highly flexible and configurable collections of cooperative services, the data mana- ment layer also has to adapt to these new requirements. Therefore, within recent years, data management systems have faced a tremendous shift from the central management of individual records in a transactional way to a platform for data integration, fede- tion, search services, and data analysis. This book addresses these new issues in the area of data management from multiple perspectives, in the form of individual contributions, and it outlines future challenges in the context of data management. These contributions are dedicated to Prof. em. Dr. Dr. -Ing. E. h. Hartmut Wedekind on the occasion of his 70th birthday, and were (co-)authored by some of his academic descendants. Prof. Wedekind is one of the most prominent figures of the database management community in Germany, and he enjoys an excellent international reputation as well. Over the last 35 years he greatly contributed to making relational database technology a success. As far back as the early 1970s, he covered—as the first author in Germany— the state of the art concerning the relational model and related issues in two widely used textbooks “Datenbanksysteme I” and “Datenbanksysteme II”. Without him, the idea of modeling complex-structured real-world scenarios in a relational way would be far less developed by now. Among Prof.

In den letzten Jahren haben neue Anwendungen und Einsatzgebiete im Bereich der Datenbankverwaltung zahlreiche neuartige Forschungsprobleme und Entwicklungsaufgaben hervorgebracht. Dabei handelt es sich vorwiegend um Anwendungen aus den Gebieten CAD/CAM, VLSI-Entwurf, Software-Entwicklung, geographische Informationssysteme, Büroautomatisierung, Expertensysteme usw., die oft als Non-Standard-Anwendungen zusammengefaßt werden. In vielen Forschungsprojekten werden bereits aussichtsreiche Lösungsvorschläge für solche Aufgabenstellungen untersucht und durch Prototypimplementierungen getestet. Dadurch lassen sich Leistungsverhalten und andere Systemeigenschaften künftiger Datenhaltungssysteme schon relativ genau charakterisieren. Ziel dieses Informatik-Fachberichtes ist es, eine aktuelle Darstellung und Diskussion der Probleme und Anforderungen sowie der neuen Forschungs- und Entwicklungsergebnisse im Bereich der Datenbankverwaltung für Non-Standard-Anwendungen zu bieten. Solche Datenhaltungsprobleme stellen nicht nur interessante Aufgaben für die Datenbankforschung dar, sondern sprechen auch aktuelle Themen in vielen Bereichen der Praxis an. Die Beiträge der Fachtagung werden thematisch zu folgenden Sitzungen zusammengefaßt: Anwendungen I, Parallelität und Synchronisation, Integrität, Wissensbasierte DB-Ansätze, Implementierungsaspekte, Anwendungen II, Leistungsaspekte, Rekursion.

Dieser Band ist der Tagungsbericht eines gemeinsamen Workshops zweier thematisch verwandter Sonderforschungsbereiche, des SFB 124 "VLSI-Entwurfsmethoden und Parallelitat" an den Universitaten Kaiserslautern und Saarbrucken und des SFB 182 "Multiprozessor- und Netzwerkkonfigurationen" an der Universitat Erlangen-Nurnberg. In dem Internationalen Begegnungs- und Forschungszentrum fur Informatik Schloss Dagstuhl wurden sieben Arbeitssitzungen zu folgenden Themenkreisen abgehalten: Strukturen verteilter und paralleler Rechensysteme, Entwurfssprachen und -systeme, Architekturen verteilter Betriebssysteme, Leistungsanalyse und -bewertung, Kommunikation in verteilten Systemen, verteilte Verarbeitungsmodelle fur Datenbankanwendungen, Anwendungen. Der Tagungsband ist Prof. Wolfgang Handler zum 70. Geburtstag gewidmet "in Anerkennung seiner Pionierleistung auf dem Gebiet der Parallelrechner".

This volume is the second one of the 16th East-European Conference on Advances in Databases and Information Systems (ADBIS 2012), held on September 18-21, 2012, in Poznań, Poland. The first one has been published in the LNCS series.  This volume includes 27 research contributions, selected out of 90. The contributions cover a wide spectrum of topics in the database and information systems field, including: database foundation and theory, data modeling and database design, business process modeling, query optimization in relational and object databases, materialized view selection algorithms, index data structures, distributed systems, system and data integration, semi-structured data and databases, semantic data management, information retrieval, data mining techniques, data stream processing, trust and reputation in the Internet, and social networks. Thus, the content of this volume covers the research areas from fundamentals of databases, through still hot topic research problems (e.g., data mining, XML data processing), to novel research areas (e.g., social networks, trust and reputation, and data stream processing). The editors of this volume believe that its content will inspire the researchers with new ideas for future development. It may also serve as an overview of the ongoing work in the field of databases and information systems.

This book constitutes the thoroughly refereed proceedings of the 16th East-European Conference on Advances in Databases and Information Systems (ADBIS 2012), held in Poznan, Poland, in September 2012. The 32 revised full papers presented were carefully selected and reviewed from 122 submissions. The papers cover a wide spectrum of issues concerning the area of database and information systems, including database theory, database architectures, query languages, query processing and optimization, design methods, data integration, view selection, nearest-neighbor searching, analytical query processing, indexing and caching, concurrency control, distributed systems, data mining, data streams, ontology engineering, social networks, multi-agent systems, business process modeling, knowledge management, and application-oriented topics like RFID, XML, and data on the Web.
