Deploying Data Warehouses in Grids with Efficiency and Availability

Authors

Abstract

Many global organizations are generating huge volumes of data, which are stored in highly distributed databases. These databases can be put together through a Grid infrastructure in order to form a large virtual data warehouse, which is physically distributed but can be transparently queried by Grid participants. But in Grids the system environment is heterogeneous and resource availability may vary over time, which may lead to performance degradation and data unavailability. In this chapter, the authors present Grid-NPDW which uses specialized data placement and job scheduling strategies in order to construct a Grid-based data warehouse with high performance and availability.
