The classification of query languages, according to certain criteria, is discussed. Reference and Idea Language (RIDL) from Control Data is examined in detail and its role as a semantic network language is assessed in relation to a database containing information of aircraft
    types. IBM's Structural English Query Language (SQL), developed for use on a relational DBMS, is also examined and compared with RIDL. Conceptual and usage differences are discussed and similarities assessed.
