SkyQuery: A Web Service Approach to Federate Databases

Tanu Malik, Alexander S. Szalay, Tamas Budavari, Ani Thakar
2003 Conference on Innovative Data Systems Research  
In this paper, we present SkyQuery, a successful prototype of an evolving federation of astronomy archives. It interoperates using the emerging Web services standard.  ...  Ineffective integration will result in defunct federations and under utilized scientific data. Astronomy, in particular, has many autonomous archives spread over the Internet.  ...  In this paper, we present SkyQuery [Sky02], a successful prototype of one of the first proposed federations of astronomy archives.  ...

2002 arXiv   pre-print
We present two prototype applications, the SdssCutout and the SkyQuery as examples of this layered architecture.  ...  SkyQuery is a portal 4 that federates five geographically separate archives and web services.  ...  The SkyQuery portal sorts count results by decreasing counts, and then creates a federated query plan.  ...

A Black-Box Approach to Query Cardinality Estimation

Tanu Malik, Randal C. Burns, Nitesh V. Chawla
2007 Conference on Innovative Data Systems Research  
Our primary case study is the Open SkyQuery federation of Astronomy archives, which uses a scheduling and caching mechanism at the mediator for execution of federated queries at remote sources.  ...  Also, the black-box approach provides dramatic improvements in the performance of caching in Open SkyQuery.  ...  We also thank Xiaodan Wang for his help the experimental section and explaining the gory details of the Open SkyQuery source code.  ...

Probabilistic Record Linkage in Astronomy: Directional Cross-Identification and Beyond

Tamás Budavári, Thomas J. Loredo
2015 Annual Review of Statistics and Its Application  
Modern astronomy increasingly relies upon systematic surveys, whose dedicated telescopes continuously observe the sky across varied wavelength ranges of the electromagnetic spectrum; some surveys also  ...  Such astronomical versions of the record linkage problem are known by various terms in astronomy: cross-matching, cross-identification, and directional, positional, or spatio-temporal coincidence assessment  ...  Section 4 is concerned with the practical implementation and describes a widely used online service called SkyQuery that can dynamically federate archives of astronomical data.  ...

Bypass Caching: Making Scientific Databases Good Network Citizens

T. Malik, R. Burns, A. Chaudhary
21st International Conference on Data Engineering (ICDE'05)  
Scientific database federations are geographically distributed and network bound. Thus, they could benefit from proxy caching.  ...  Bypass-yield caching is altruistic; caches minimize the overall network traffic generated by the federation, rather than focusing on local performance.  ...  Experiments We develop bypass-yield caching within the SkyQuery [27] federation of astronomy databases.  ...
