KDB is a popular trading database. Unenjoyable but effective seems par for the course with high frequency trading; C++ is notoriously difficult to work with. Learning KDB is still worth it, according to Paul Bilokon, an expert software engineer who has built advanced financial frameworks on Wall Street and in the City..
What is KDB good for?
Powerful language kdb+ is very useful in the trading world as it allows analysts to look at huge amounts of data quickly and somewhat easily. Speed was a huge factor..
What is KDB programming language?
Kdb+ is a powerful database that can be used for streaming, real-time and historical data. Q is the SQL-like, general-purpose programming language built on top of kdb+. It offers high-performance, in-database analytic capabilities. Get started to download and install kdb+..
Where is KDB used?
The database is commonly used in high-frequency trading (HFT) to store, analyze, process, and retrieve large data sets at high speed..
kdb+ was created by Arthur Whitney, building on his prior work with array languages.

kdb+, introduced in 2003, is the new generation of the kdb database which is designed to capture, analyze, compare, and store data. Both kdb+ and q are written in k programming language (same as q but less readable).

Is kdb+ a database?
Kdb+ is a database. You can use it through interfaces such as:
ODBC
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.

What is Q language in kdb+?
The q language¶ Q is the programming system for working with kdb+. This corresponds to SQL for traditional databases, but unlike SQL, q is a powerful programming language in its own right. Q is an interpreted language. Q expressions can be entered and executed in the q console, or loaded from a q script, which is a text file with extension .q.

What languages does KDB+ support?
The database supports SQL, SQL-92and ksql, a query language with a syntax similar to SQL and designed for column based queries and array analysis. Kdb+ is available for several operating systems, including:
Solaris
Linux
macOS
Windows(32-bit or 64-bit)
Kdb programming language
Programming language
A+ is a high-level, interactive, interpreted array programming language designed for numerically intensive applications, especially those found in financial applications.
High-speed database
kdb+ is a column-based relational time series database (TSDB) with in-memory (IMDB) abilities, developed and marketed by KX. The database is commonly used in high-frequency trading (HFT) to store, analyze, process, and retrieve large data sets at high speed. kdb+ has the ability to handle billions of records and analyzes data within a database. The database is available in 32-bit and 64-bit versions for several operating systems. Financial institutions use kdb+ to analyze time series data such as stock or commodity exchange data. The database has also been used for other time-sensitive data applications including commodity markets such as energy trading, telecommunications, sensor data, log data, machine and computer network usage monitoring along with real time analytics in Formula One racing.

Interactive, extensible programming language type
The Polymorphic Programming Language (PPL) was developed in 1969 at Harvard University by Thomas A. Standish. It is an interactive, extensible language with a base language similar to the language APL.
Rank is a generalization of looping as used in scalar (non-array-oriented) programming languages. It is also a generalization of mapcar in the language Lisp and map in modern functional programming languages, and a generalization of scalar extension, inner (matrix) product, and outer product in APL\\360. The canonical implementation of rank may be the language J, but it is also available in Dyalog APL, the International Organization for Standardization (ISO) technical standard on Extended APL, and NARS2000.
