Q is a proprietary array processing language developed by Arthur Whitney and commercialized by Kx Systems. The language serves as the query language for KDB+, a disk based and in-memory, column-based database. Kdb+ is based upon K, a terse variant of APL. Q is a thin wrapper around K, providing a more readable, English like interface.[2]
