一种基于事例推理的数据库模式设计专家系统的体系结构

Research and Construction of an Ecpert System with Case-Based Reasoning for Database Schema Design

提出一种基于事例推理的 DB模式设计专家系统 DES- DS的体系结构 ,分别从设计需求说明的表达 ,设计事例的表达、组织与检索、调整与学习等几个方面来探讨 DB模式设计问题求解中的事例推理技术 ,旨在提高 DB模式设计的效率和质量 .

Database schema design is the core task in developing information system.A Design Expert System for Database Schema(DES DS) is proposed based upon case based reasoning.In order to solve the database schema design problems by using CBR technipues,the representations of the users' design specification and previous design cases,organization and retrieval of th case bases,adjustment and learning of the cases are described respectively.Hence the efficiency and effectiveness of database schema design can be improved.
