Administrative HistoryCODASYL (Conference on Data Systems Languages) was a consortium formed in 1959 with the aim of developing a standard programming language. The University of Aberdeen were active members of this consortium and its various task groups from the mid-1970s to the early 1980s, attending meetings in the United States and Europe on a regular basis. A List Processing Task Force was created in 1965 (renamed the Database Task Group (DBTG) in 1967). Its purpose was to develop COBOL language extensions for processing collections of records. In 1969 it produced the Codasyl Data Model (a network database model) which was based on several separate languages including a data description language (DDL) and a data manipulation language (DML). The Data Description Language Committee (DDLC) was established in 1971 with a view to developing a database not dependent on a specific programming language. The specifications produced by the DBTG were used as the basis for a number of database products including Honeywell's Integrated Data Store (IDS/2). By the mid-1980s CODASYL as an organisation appeared to lose some focus and the University ceased to be members.
