It introduces ADQL, a specialized query language with extensions and restrictions to SQL92, designed specifically for astronomical data analysis.
Findings
ADQL supports astronomy-specific operations.
Extensions to SQL92 enable specialized data queries.
The language standardizes astronomical data access.
Abstract
This document describes the Astronomical Data Query Language (ADQL). ADQL has been developed based on SQL92. This document describes the subset of the SQL grammar supported by ADQL. Special restrictions and extensions to SQL92 have been defined in order to support generic and astronomy specific operations.
