Q is a proprietary array processing language developed by Arthur Whitney and commercialized by Kx Systems. The language serves as the foundation for KDB, an in-memory, column-based database, and other related financial products. The language is built on top of K[2] and provides access to the underlying K interpreter. One enhancement in Q is it provides access to database dictionaries and tables in a manner similar to APL's arrays.[1]
