On behalf of the OGSA-DQP team: Hi All It is a pleasure to announce the third release of OGSA-DQP (Open Grid Services Architecture Distributed Query Processor). OGSA-DQP allows queries to be evaluated over multiple distributed relational databases, where the queries may include calls to web services. The software architecture accesses relational databases using OGSA-DAI (http://www.ogsadai.org.uk), and supports both pipelined and partitioned parallelism. More details about OGSA-DQP can be found at: http://www.ogsadai.org.uk/dqp/ The OGSA-DQP Coordinator Service can now be deployed on to either WSRF or WS-I platforms, using either OGSA-DAI WSRF 2.1 or OGSA-DAI WS-I 2.1 to access the databases referenced in queries. The query evaluation service only requires a WS-I platform, which minimises requirements and allows a simple deployment to be made using WAR files. Furthermore, the query compiler and optimiser can now be built using Cygwin, allowing the coordinator service to be deployed on Windows as well as Linux. This new release also contains some major improvements in query compilation/optimisation and evaluation with respect to performance, multiple bug fixes and a new command line client. A gzipped tarball and winzipped distribution of the source code can be obtained from: http://www.ogsadai.org.uk/downloads If you have previously downloaded OGSA-DAI or OGSA-DQP then the same user name and password will work, otherwise please register to obtain the username/password at: http://www.ogsadai.org.uk/download.cgi?OGSA-DQP This software is released under the OGSA-DAI Project license which is available at http://www.ogsadai.org.uk/releases/dqp.php. We are happy to receive feedback. Please send any queries or bugs to the OGSA-DAI User Mailing list users@ogsadai.org.uk (note that you need to be registered to post to this list, to register see: http://www.ogsadai.org.uk/support/list.php) or the support help desk (support@ogsadai.org.uk). OGSA-DQP was designed and developed at the Universities of Manchester and Newcastle, UK. It was funded by the UK e-Science programme through the OGSA-DAI, DAIT and myGrid projects.
