Interactive Synthesis of Conceptual Schema Based on Queries : Towards an Expert System of Relational Database Design

概要
- 論文の詳細を見る
In this paper we consider the problem of designing conceptual schema from a set of queries stated in English. Our system reads a set of queries to the target database, obtains a set of Prolog unit clauses representing the conceptual schema of the database and generates a file creation program of a DBMS. Syntax-based operations are mainly used in the generation process without a priori knowledge of the data under consideration. It first ex-tracts syntactic dependencies between nouns and identifies attributes. Next, it eliminates redundancies existing in the logical constituents obtained and finally produces conceptual schema by gathering them. Semantic information necessary for designing a logical structure is obtained through the interaction with the user. A prototype system for DBMS "INQ" has been implemented in Prolog.
