OGSA-DQP is a distributed query processor exposed to users as an Open Grid Services Architecture (OGSA)-compliant Grid service. This service supports the compilation and evaluation of queries that combine data obtained from multiple services on the Grid, including Grid Database Services (GDSs) and computational web services. Not only does OGSA-DQP support integrated access to multiple Grid services, it is itself implemented as a collection of interacting Grid services. OGSA-DQP illustrates how Grid service orchestrations can be used to perform complex, data-intensive parallel computations. The OGSA-DQP prototype is downloadable from This demonstration aims to illustrate the capabilities of OGSA-DQP prototype via a GUI Client over a collection of bioinformatics databases and analysis tools.
