SkyQuery: A Web Service Approach to Federate Databases

Summary: SkyQuery demonstrates a pragmatic Web-services–based federation of autonomous, heterogeneous astronomy archives to build a Virtual Observatory with minimal integration effort. Describes an architecture and optimizations for evaluating probabilistic federated spatial-join queries. (summarized by gpt-5-mini on Feb 09 2026)
