Data-Intensive Grid Computing Based on Updatable Views
974
Abstract
In this report we propose a new approach to integration of distributed
heterogeneous resources on the basis of a canonical object-oriented
database model, a query language and updateable database views. Views
are used as wrappers/mediators on top of local servers and as a data
integration facility for global applications. Views support location,
implementation and replication transparency. Because views are defined
in a high-level query language, the mechanism is much more abstract and
flexible in comparison to e.g. CORBA or Web Services. The report
presents a short introduction to the query language SBQL and updateable
views. It also presents the architecture of the grid network based on
updateable views, and simple examples illustrating the mechanism. In the
report we also show how the mechanism can be used in peer-to-peer
networks. We shortly describe the process of grid design and
development. Finally, we present some issues related to grid metadata.
Keywords: grid computing, Stack-Based Approach, updateable views.
