"Hello, World!" program

A "Hello, World!" program is a computer program that outputs or displays "Hello, World!" to a user.

A+ (programming language)

A+ is an array programming language descendent from the programming language A, which in turn was created to replace APL in 1988.

APL (programming language)

APL (named after the book A Programming Language) is a programming language developed in the 1960s by Kenneth E. Iverson.

Array data structure

In computer science, an array data structure, or simply an array, is a data structure consisting of a collection of elements (values or variables), each identified by at least one array index or key.

Array programming

In computer science, array programming languages (also known as vector or multidimensional languages) generalize operations on scalars to apply transparently to vectors, matrices, and higher-dimensional arrays.

Arthur Whitney (computer scientist)

Arthur Whitney (born October 24, 1957) is a Canadian computer scientist most notable for developing three programming languages inspired by APL: A+, K, and Q, and for cofounding the U.S. company Kx Systems.

Associative array

In computer science, an associative array, map, symbol table, or dictionary is an abstract data type composed of a collection of (key, value) pairs, such that each possible key appears at most once in the collection.

Column-oriented DBMS

"A column-oriented DBMS"(or columnar database management system) is a database management system (DBMS) that stores data tables by column rather than by row.

Data type

In computer science and computer programming, a data type or simply type is a classification of data which tells the compiler or interpreter how the programmer intends to use the data.

Database

A database is an organized collection of data, stored and accessed electronically.

New!!: Q (programming language from Kx Systems) and Database · See more »

Functional programming

In computer science, functional programming is a programming paradigm—a style of building the structure and elements of computer programs—that treats computation as the evaluation of mathematical functions and avoids changing-state and mutable data.

In-memory database

An in-memory database (IMDB, also main memory database system or MMDB or memory resident database) is a database management system that primarily relies on main memory for computer data storage.

K (programming language)

K is a proprietary array processing programming language developed by Arthur Whitney and commercialized by Kx Systems.

Kx Systems

Kx Systems is a data analysis software developer and vendor.

List (abstract data type)

In computer science, a list or sequence is an abstract data type that represents a countable number of ordered values, where the same value may occur more than once.

Programming language

A programming language is a formal language that specifies a set of instructions that can be used to produce various kinds of output.

Proprietary software

Proprietary software is non-free computer software for which the software's publisher or another person retains intellectual property rights—usually copyright of the source code, but sometimes patent rights.

Scheme (programming language)

Scheme is a programming language that supports multiple paradigms, including functional programming and imperative programming, and is one of the two main dialects of Lisp.

SQL

SQL (S-Q-L, "sequel"; Structured Query Language) is a domain-specific language used in programming and designed for managing data held in a relational database management system (RDBMS), or for stream processing in a relational data stream management system (RDSMS).

Strong and weak typing

In computer programming, programming languages are often colloquially classified as to whether the language's type system makes it strongly typed or weakly typed (loosely typed).

Table (database)

A table is a collection of related data held in a structured format within a database.

Type system

In programming languages, a type system is a set of rules that assigns a property called type to the various constructs of a computer program, such as variables, expressions, functions or modules.

Unique key

In database relational modeling and implementation, a unique key (also known as a candidate key) of a relation is a minimal superkey for that relation; that is, a set of attributes such that.

Variable (computer science)

In computer programming, a variable or scalar is a storage location (identified by a memory address) paired with an associated symbolic name (an identifier), which contains some known or unknown quantity of information referred to as a value.
