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.
