CODASYL originated in the United States on 28 and 29 May 1959 a meeting of computer owners with government, military and private sector as well as computer manufacturers and other interested parties with the purpose to discuss the development of a common programming language in a compatible manner on computers of various manufacturers should work.

The first product of CODASYL is the COBOL programming language, a further development of standardized methods for defining the structure (Data Definition Language) and processing (Data Manipulation Language ) of network database systems, which are known as CODASYL databases in this form, by the Data Base task Group ( DBTG ).

Some of CODASYL committees are still working, but CODASYL as such no longer exists; the archived documents were presented to the Charles Babbage Institute of Computer History at the University of Minnesota, USA passed.
