COBOL (/ ˈ k oʊ b ɒ l,-b ɔː l /; an acronym for "common business-oriented language") is a compiled English-like computer programming language designed for business use. It is an imperative, procedural, and, since 2002, object-oriented language. COBOL is primarily used in business, finance, and administrative systems for companies and ...

IBM COBOL. IBM has offered the computer programming language COBOL on many platforms, starting with the IBM 1400 series and IBM 7000 series, continuing into the industry-dominant IBM System/360 and IBM System/370 mainframe systems, and then through IBM Power Systems (AIX), IBM Z (z/OS and z/VSE), and x86 (Linux).

COBOL was created because people wanted a language they could use to describe the problems in a way that is independent of the hardware used. Like SQL COBOL uses a syntax that is close to that of natural languages. As an example, ADD YEARS TO AGEis a valid expression.
There are several different versions of COBOL. The newest is from 2002. In general, versions of the language before 1985are not compatible with the newer versions, from 1985 and later. In his letter to an editor in 1975 titled "How do we tell truths that might hurt?", computer scientist and Turing Award recipient Edsger Dijkstra remarked that "The ...
The computer scientistHoward E. Tompkins disagreed, and defended structured COBOL: "COBOL programs with convoluted control flow indeed tend to 'cripple the mind'", but this was because "there are too many such business application programs written by programmers that have never had the benefit of structured COBOL taught well...".
CODASYL, the Conference/Committee on Data Systems Languages, was a consortium formed in 1959 to guide the development of a standard programming language that could be used on many computers. This effort led to the development of the programming language COBOL, the CODASYL Data Model, and other technical standards.
