kdb+ is a database. You can use it through interfaces such as ODBC, or from Python, but its power and performance are best accessed through its own language, q. Q is a general-purpose programming language. You can write programs for anything in q. You do not need prior programming experience to learn it.

On this site, string is a synonym for character vector (type 10h). In q, the nearest equivalent to an atomic string is the symbol. Strings can include multibyte characters, which each occupy the respective number of bytes. For example, assuming that the input encoding is UTF-8: Other encodings may give different results. Unicode.

This Visual Studio Code extension provides extensive features for the kdb+/q programming language. Features include syntax highlighting, auto completion, executing queries on a kdb+ server, table visualization and more. The extension is developed with Atom's connect-kdb-q extension and QInsightPad in mind.
