05421 Abstracts Collection – Data Always and Everywhere – Management of Mobile, Ubiquitous, Pervasive, and Sensor Data

Authors: Gustavo Alonso, Christian S. Jensen, and Bernhard Mitschang

Abstract
From 16.10.05 to 21.10.05, the Dagstuhl Seminar 05421, Data Always and Everywhere - Management of Mobile, Ubiquitous, Pervasive, and Sensor Data, was held in the International Conference and Research Center, Schloss Dagstuhl. During the seminar, all participants were given the opportunity to present their current research, and ongoing activities and open problems were discussed. This document is a collection of the abstracts of the presentations given during the seminar. Some abstracts offer links to extended abstracts, full papers, and other supporting documents. A separate companion document summarizes the seminar. The authors wish to acknowledge Victor Teixeira de Almeida, who served as collector for the seminar and thus played a key role in collecting materials from the seminar participants.

05421 Executive Summary – Data Always and Everywhere – Management of Mobile, Ubiquitous, and Pervasive Data

Authors: Gustavo Alonso, Christian S. Jensen, and Bernhard Mitschang

Abstract
This report summarizes the important aspects of the workshop on "Management of Mobile, Ubiquitous, and Pervasive Data", which took place from October 16th to October 21st, 2005. Thirty-seven participants from thirteen countries met during that week and discussed a broad range of topics related to the management of data in relation to mobile, ubiquitous, and pervasive applications of information technology. The wealth of the contributions is available at the seminar page at the Dagstuhl server. Here, we provide a short overview.

B-tree indexes for high update rates

Authors: Goetz Graefe

Abstract
In some applications, data capture dominates query processing. For example, monitoring moving objects often requires more insertions and updates than queries. Data gathering using automated sensors often exhibits this imbalance. More generally, indexing streams apparently is considered an unsolved problem. For those applications, B-tree indexes are reasonable choices if some trade-off decisions are tilted towards optimization of updates rather than of queries. This paper surveys techniques that let B-trees sustain very high update rates, up to multiple orders of magnitude higher than tradi-tional B-trees, at the expense of query processing performance. Perhaps not surprisingly, some of these techniques are reminiscent of those employed during index creation, index rebuild, etc., while others are derived from other well known technologies such as differential files and log-structured file systems.

Media Distribution in a Pervasive Computing Environment

Authors: Alexander Sinitsyn, Winfried A. H. Berkvens, Arjan Claassen, and Joep P. van Gassel

Abstract
Distribution of media in the fast growing world of digital stored content and multimedia supporting devices with connectivity, calls for a new media distribution architecture. The user should be provided with the experience of having an overview of his full media collection, regardless of the time, the place, and the connectivity. Transparent distributed data management is crucial to Ambient Intelligent applications. The proposed media distribution architecture offers a possible solution. It provides the user with the experience of having all his media collections available at any time, in any place, and managing them regardless of connection availability in the heterogeneous environment. This experience is enabled in our system by the separation of metadata and content handling. Other features are efficient handling of snapshots, usage of various database technologies, and leveraging device and service discovery mechanisms.
