| Abstract: |
SciQL (pronounced as ‘cycle’) is a novel SQL-based array query language for
scientific applications with both tables and arrays as first class citizens.
SciQL lowers the entrance fee of adopting relational DBMS (RDBMS) in scientific
domains, because it includes functionality often only found in mathematics
software packages.
In this paper, we demonstrate the usefulness of SciQL for astronomical data
processing using examples from the Transient Key Project of the LOFAR radio
telescope.
In particular, how the LOFAR light-curve database of all detected sources can
be constructed, by correlating sources across the spatial, frequency, time and
polarisation domains. |
