Abstract

This paper explores the use of Grid technologies for the manipulation of the Sloan Digital Sky Survey (SDSS) database. The paper first provides background information on the SDSS database, OGSA-DAI operations and OGSA-DQP operators. We then analyse the execution of OGSA-DQP for querying a heterogeneous distributed version of the SDSS database. In particular, we examine the different SOAP interactions between OGSA-DQP components and look at simple queries plans. After modifying the OGSA-DQP coordinator we successfully ran OGSA-DQP queries against the distributed SDSS database.
