Get started with q and kdb+

 

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. If you have some experience with mathematics, functional programming or SQL, you will find in q much that is familiar.

In this section we offer different routes into the language. Find one that suits your experience and learning style. (Or ask the Librarian for what you need.)

Other sections:

Language formal definition of language elements
Database persisting tables in the filesystem
Architecture topics in building systems using kdb+ processes
White papers extended treatments of topics in q programming and in building kdb+ systems
