Programming Language

K

Array Language

K is a proprietary array programming language developed by Arthur Whitney, derived from APL and closely related to J, first released in 1993 and commercialized by Kx Systems. K is best known as the language underlying kdb+, a high-performance column-oriented database widely used in the financial industry for processing large volumes of time-series data, and it shares the terse, symbol-dense syntax of APL while further emphasizing execution speed.
