Abstract

This paper presents a high-level data sublanguage called SLICK for the manipulation and retrieval of data from normalized and unnormalized (hierarchically structured) relational tables. The language is designed to express the process used by information users to extract information from the tables. It eliminates the need for using extra variables, allows retrieval operations to be performed directly on unnormalized tables, and matches with the specific implementation of a context-addressed memory system. The language elements and their use are described and illustrated in many example retrieval statements. The simplicity of mapping high level statements to basic machine instructions for the memory system is demonstrated.
