Local Join Optimization over a Heterogeneously Distributed Scientific Database
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
This paper begins by discussing the running of the first distributed queries across a heterogeneously distributed scientific database between Manchester and Portsmouth. It then investigates the join operations over the ...
Query optimization over a heterogeneously distributed scientific database
(Institute of Electrical and Electronics Engineers (IEEE), 2013)
This paper briefly discusses the concepts about distributed databases management system and distributed query processing. It then talks about the need of distributing large Scientific datasets such as the Sloan Digital Sky ...
Integrated queries over a heterogeneously distributed scientific database using OGSA-DQP
(Institute of Electrical and Electronics Engineers (IEEE), 2011)
In this paper we experiment with using the UNION ALL operator to make data integration queries over a version of the SDSS scientific Database, distributed using OGSA-DQP. The paper starts with background information on the ...
