【摘要】 本文提出了一个基于关系数据库的Prolog系统,目的是使Prolog这个强有力的程序语言具有处理检索问题的能力,以适应于演绎和检索的共同需要.这个系统已在IBM-PC上初步实现.本文着重阐述了这种一体化系统在理论上及实际应用中的价值,系统的设计特点及其实现.更多还原

【Abstract】 In this paper,a PROLOG system based on a relational data base is described.The direction of my work is to produce a PROLOG system that is equally good for both data base and programming purpose.The method of our design is to combine the existing relational data base with PROLOG system in such a way as to allow deduction and control to be performed by PROLOG excuting mechanism while large amount of data retrieval to be handled by a relational data base.This system is implemented on IBM-PC in C programming language.更多还原
