Astronomical Data Query Language

The Astronomical Data Query Language (ADQL) is the language used by the IVOA to represent astronomy queries posted to VO services. ADQL is based on the Structured Query Language, especially SQL 92; special restrictions and extensions have been defined in order to support generic and astronomy specific operations.
