"The LEGOL 1 Prototype System and Language" view details Abstract: Research into the problems of information analysis is being carried out using legislation as experimental material. A body of administrative law may define the tasks of a man/machine information system and, by attempting to construct a formalism (LEGOL), in which such law may be express, it is possible to study the logical structure of formal systems. A prototype version of the formalism and of its interpreter system are described. Theoretical problems are raised in the fields of data base semantics, very high level languages, use of relational data bases, design decision-making and of the methodology of research in the field of information analysis.

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.
