The contract ended in 1997 when UBS merged with Swiss Bank. In 1998, Kx Systems released kdb+, a database built on K. kdb was an in-memory, column-oriented database and included ksql, a query language with an SQL-like syntax. Since then, several financial products have been developed with K and kdb+. kdb+/tick and kdb+/taq were developed in 2001. kdb+, a 64-bit version of kdb+ was released in 2003 and kdb+/tick and kdb+/taq were released in 2004. kdb+ included Q, a language that merged the functions of the underlying K language and ksql.
