GeoSensor networks : second international conference, GSN 2006, Boston, MA, USA, October 1-3, 2006 : revised selected and invited papers by Silvia Nittel( Book )
15 editions published in 2008 in English and Undetermined and held by 86 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

Reduction of materialized view staleness using online updates by Alexandros Labrinidis( Book )
1 edition published in 1998 in English and held by 1 library worldwide
Updating the materialized views stored in data warehouses usually implies making the warehouse unavailable to users. We propose MAUVE, a new algorithm for online incremental view updates that uses timestamps and allows consistent read-only access to the warehouse while it being updated. The algorithm propagates the updates to the views more often than the typical once a day in order to reduce view staleness. We have implemented MAUVE top of the Informix Universal Server and used a synthetic workload generator to experiment with various update workloads and different view update frequencies. Our results show that, all kinds of update streams benefit from more frequent view updates, instead of just once a day. However, there is a clear maximum for the view update frequency, for which view staleness is minimal

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

On the Materialization of WebViews ( file )
1 edition published in 1999 in English and held by 0 libraries worldwide
A WebView is a web page that is automatically created from base data, which are usually drawn from a DBMS. A WebView can be either materialized as an html page at the web server, or virtual, always being computed on-the-fly. For the materialized case, updates to base data lead to immediate recomputation of the WebView, whereas in the virtual case, recomputation is done on demand with each request. We introduce the materialize on-demand approach which combines the two strategies, and generates WebViews on demand, but also stores the results and re-uses them in the future if possible. Deciding on one of the three materialization policies for each WebView is clearly a performance issue. In this paper, we give the framework for the problem and provide a cost model, which we test with experiments on a real web server
