Relational Database Query Formulation

Keywords: Relational Calculus, entity-relationship

Categories: Natural Language


Author(s): Jim Longstaff

A technique for specifying queries and other interactions against the relational and entity-relationship data models. Database semantics are initially presented as a hierarchy of functional areas, leading to entity-relationship/relational description. A naive-user mode provides system initiated dialogue with natural language statements of queries (i.e., paraphrases of relational calculus expressions) displayed for user validation. Self-teaching system, with simple `user controlled' inferencing.
