This work presents a disconnected transaction model able to cope with the increased complexity of longliving, hierarchically structured, and disconnected transactions. Wecombine an Open and Closed Nested Transaction Model with Optimistic Concurrency Control and interrelate flat transactions with the aforementioned complex nature. Despite temporary inconsistencies during a transaction’s execution our model ensures consistency.
Social Media
(2011)
In jüngerer Zeit gewinnt die Nutzung des Internet für das Inbound Marketing zunehmend an Bedeutung. Dabei liegt der Fokus auf den so genannten Social Media Plattformen wie Facebook, YouTube, MySpace, XING, LinkedIn, Twitter, SlideShare und Posterous. Die Entwicklung dieser Medien ist auf eine Veränderung bei der Nutzung des Internet zurückzuführen, die häufig unter dem Schlagwort Web 2.0 zusammengefasst wird. Das gewandelte Mediennutzungsverhalten der Kunden induziert Chancen und Risiken für das Marketing.
Das Internet gewinnt für das Marketing zunehmend an Bedeutung. Dabei liegt der Fokus auf sogenannten Social-Media-Anwendungen wie Facebook, Twitter oder XING. Für Unternehmen stellt sich die Frage, ob das veränderte Mediennutzungsverhalten der Kunden eine neue Marketinglogik induziert. Eine aktuelle Untersuchung gibt Einblicke in die Chancen und Risiken, Anwendungsbedingungen und Kontextfaktoren für die Nutzung von Social Media im Marketing.
Suppliers need to improve their relational capabilities if they are to enhance customer trust. Debate about such capabilities is dominated by an interpersonal approach.

Die Informatics Inside-Konferenz findet in diesem Jahr zum dritten Mal statt. Mit dem Thema "Grenzen überwinden – Virtualität erweitert Realität" stellt sich die Veranstaltung einem aktuellen Schwerpunkt, der viele Interessierte aus Wirtschaft, Wissenschaft und Forschung anzieht. Die Konferenz hat sich von einer Veranstaltung für die Masterstudenten des Studiengangs Medien- und Kommunikationsinformatik zu einer offenen Studentenkonferenz entwickelt. Um die Qualität weiter zu steigern wurde parallel dazu ein zweistufiges Review-Verfahren für Beiträge dieses Tagungsbandes eingeführt.
The Third International Conference on Advances in Databases, Knowledge, and Data Applications (DBKDA 2011) held on January 23-27, 2011 in St. Maarten, The Netherlands Antilles, continued a series of international events covering a large spectrum of topics related to advances in fundamentals on databases, evolution of relation between databases and other domains, data base technologies and content processing, as well as specifics in applications domains databases. Advances in different technologies and domains related to databases triggered substantial improvements for content processing, information indexing, and data, process and knowledge mining. The push came from Web services, artificial intelligence, and agent technologies, as well as from the generalization of the XML adoption. High-speed communications and computations, large storage capacities, and load-balancing for distributed databases access allow new approaches for content processing with incomplete patterns, advanced ranking algorithms and advanced indexing methods. Evolution on e-business, ehealth and telemedicine, bioinformatics, finance and marketing, geographical positioning systems put pressure on database communities to push the ‘de facto’ methods to support new requirements in terms of scalability, privacy, performance, indexing, and heterogeneity of both content and technology. We take this opportunity to thank all the members of the DBKDA 2011 Technical Program Committee as well as the numerous reviewers. The creation of such a broad and high-quality conference program would not have been possible without their involvement. We also kindly thank all the authors who dedicated much of their time and efforts to contribute to the DBKDA 2011. We truly believe that, thanks to all these efforts, the final conference program consists of top quality contributions. This event could also not have been a reality without the support of many individuals, organizations, and sponsors. We are grateful to the members of the DBKDA 2011 organizing committee for their help in handling the logistics and for their work to make this professional meeting a success. We hope that DBKDA 2011 was a successful international forum for the exchange of ideas and results between academia and industry and for the promotion of progress in database research. We are convinced that the participants found the event useful and communications very open. The beautiful places of St. Maarten surely provided a pleasant environment during the conference and we hope you had a chance to visit the surroundings.
