Survey of Ada (Trademark)-Based PDLs (Program Design Language)

摘要

A Programming Design Language (PDL) is an English-like artificial language, sometimes called pseudo-code, used in documenting design logic in software systems development. Computer Technology Associates and Advanced Software Methods were contracted by the NAC to conduct a survey of Ada-based PDLs to update the 1982 NAC survey of Ada-based PDLs. With the development and advancement of the Ada programming language, many Ada-based PDLs have been developed. These PDLs are designed to make full and correct use of the Ada language features and to employ the software engineering concepts contained within the Ada language. The purpose of the 1984 NAC PDL survey was to identify and investigate the current set of Ada-based PDLs, updating the existing data collected in the 1982 survey. In addition, the results will provide a foundation for an Ada-based PDL evaluation and selection procedure that is being developed by the STARS Methodology Project. The 1984 NAC PDL survey gathered information on 28 PDLs: 7 in the very early stages of development, 5 were disqualified because they failed to meet the requirements to be classified as 'Ada-based' and 16 are analyzed in detail in the Final Report.
