GeoSensor networks : second international conference, GSN 2006, Boston, MA, USA, October 1-3, 2006 : revised selected and invited papers by Silvia Nittel( Book )
16 editions published in 2008 in English and held by 89 libraries worldwide
This book constitutes the thoroughly refereed proceedings of the Second GeoSensor Networks Conference, held in Boston, Massachusetts, USA, in October 2006. The conference addressed issues related to the collection, management, processing, analysis, and delivery of real-time geospatial data using distributed geosensor networks. This represents an evolution of the traditional static and centralized geocomputational paradigm. The 13 carefully reviewed and selected papers included in the volume constitute extended versions of the papers presented at the conference. They are preceded by an introduction written by the volume editors. The book is structured in sections on Data Acquisition and Processing, Data Analysis and Integration, and Applications. The papers represent key research areas that are fundamental in order to realize the full potential of the emerging geosensor network paradigm. The contributions cover theentire spectrum of the field from low-level energy consumption issues at the individual sensor level to the high-level abstraction of events and ontologies or models to recognize and monitor phenomena using geosensor networks

Caching and materialization for web databases by Alexandros Labrinidis( Book )
4 editions published in 2010 in English and held by 6 libraries worldwide
Database systems have been driving dynamic web sites since the early 90s; nowadays, even seemingly static web sites employ a database back-end for personalization and advertising purposes. In order to keep up with the high demand fuelled by the rapid growth of the Internet, a number of caching and materialization techniques have been proposed for web databases over the years. The main goal of these techniques is to improve performance, scalability, and manageability of database-driven dynamic web sites, in a way that the quality of data is not compromised. Although caching and materialization are well understood concepts in the traditional database and networking/operating systems literature, the Web and web databases bring forth unique characteristics that warrant new techniques and approaches. In this survey, we adopt a data management point of view to describe the system architectures of web databases, and analyze the research issues related to caching and materialization in such architectures. We also present the state of the art in caching and materialization for web databases and organize current approaches according to the fundamental questions, namely how to store, how to use, and how to maintain cached/materialized web data. Finally, we associate work in caching and materialization for web databases to similar techniques in other related areas, such as data warehousing, distributed systems, and distributed databases

A performance evaluation of online warehouse update algorithms by Alexandros Labrinidis( Book )
2 editions published in 1998 in English and held by 1 library worldwide
Data warehouse maintenance algorithms usually work off-line, making the warehouse unavailable to users. However, since most organizations require continuous operation, we need be able to perform the updates online, concurrently with user queries. To guarantee that user queries access a consistent view of the warehouse, online update algorithms introduce redundancy in order to store multiple versions of the data objects that are being changed. In this paper, we present an online warehouse update algorithm, that stores multiple versions of data as separate rows (vertical redundancy). We compare our algorithm to another online algorithm that stores multiple versions within each tuple by extending the table schema (horizontal redundancy). We have implemented both algorithms on top of an Informix Dynamic Server and measured their performance under varying workloads, focusing on their impact on query response times. Our experiments show that, except for a limited number of cases, vertical redundancy is a better choice, with respect to storage, implementation overhead, and query performance

Update Propagation Strategies for Improving the Quality of Data on the Web ( file )
1 edition published in 2001 in English and held by 0 libraries worldwide
Dynamically generated web pages are ubiquitous today but their high demand for resources creates a huge scalability problem at the servers. Traditional web caching is not able to solve this problem since it cannot provide any guarantees as to the freshness of the cached data. A robust solution to the problem is web materialization, where pages are cached at the web server and constantly updated in the background, resulting in fresh data accesses on cache hits. In this work, we define Quality of Data metrics to evaluate how fresh the data served to the users is. We then focus on the update scheduling problem: given a set of views that are materialized, find the best order to refresh them, in the presence of continuous updates, so that the overall Quality of Data (QoD) is maximized. We present a QoD-aware Update Scheduling algorithm that is adaptive and tolerant to surges in the incoming update stream. We performed extensive experiments using real traces and synthetic ones, which show that our algorithm consistently outperforms FIFO scheduling by up to two orders of magnitude. Prepared through collaborative participation in the Advanced Telecommunications/Information Distribution Research Program (ATIRP) Consortium sponsored by the U.S. Army Research Laboratory under the Federated Laboratory Program, Cooperative Agreement DAAL01-96-2-0002. An abridged version of this work appears in the Proceedings of the 27th VLDB Conference, Roma, Italy, 2001

Adaptive WebView Materialization ( file )
1 edition published in 2001 in English and held by 0 libraries worldwide
Dynamic content generation poses huge resource demands on web servers, creating a scalability problem. WebView Materialization, where web pages are cached and constantly refreshed in the background, has been shown to ameliorate the scalability problem without sacrificing data freshness. In this work we present an adaptive online algorithm to select which WebViews to materialize, that realizes the trade-off between Quality of Service and Quality of Data. Our algorithm performs very close to the static, off-line optimal algorithm, and, under rapid workload changes, it outperforms the optimal
