Databases in Grid Applications: Locality and Distribution
School of Computing Science,
University of Newcastle upon Tyne
This talk focuses on two areas that experience in building
database-oriented e-science applications has shown to be important.
Firstly, methods of promoting data locality are vital due to the high
cost of moving data in service based distributed systems. Databases
provide an excellent basis for achieving this due to their potential for
moving computation to data. I will describe a new infrastructure that
further promotes locality by enabling service-based computations to
migrate to data. Secondly, the ability to combine information from a set
of distributed databases has proved invaluable in many applications. I
will describe the design of an adaptive distributed query processing
system that is able to exploit the facilities offered by an underlying
grid infrastructure. This includes dynamic re-optimisation as the pool
of available resources changes, and the ability to tolerate node
failure.
