演绎数据库的研究与实现

THE RESEARCH AND IMPLEMENTATION OF DEDUCTIVE DATABASE

讨论了演绎数据库研究的必要性,然后分析了与其相关的理论和实现方法,提出了一种有效的演绎数据库系统DDBASE的实现方法。该系统在功能上分为一般DB操作和演绎推理两部分,并为用户提供一种数据结构独立、非过程化的自主型演绎查询语言(Deductive Qcerg Language),该系统已建立在IBM PC微型机上,实验结果表明:这种实验方法是行之有效的。

The necessity to the research on deductive database,its theory and implementing method are discussed. In addition,an efficient method for designing deductive database system——DDBASE is alsopresented. The system includes a database operation and a deductive inference,and provides users with a data-structure-independence, non-procedural and independent deductive query language. DDBASE has been built in IBM PC and the experiment result has shown that the method is of great effective.
