The Table Query Language (TaQL) is an SQL-like high level language to
do operations like selection, sort, and update on a table. It is a very
versatile language with full support for table columns containing
array data. It has inherent support for units and it
has a very rich set of functions (like cone search and
array reduction) making it very suitable for astronomical
applications. It also has full support of nested queries.
An operation that can be expressed in a single function is the
matching of two sky catalogues.
A binding in C++, Python, and Glish is available.
