摘　　要：本文论述了用Prolog子句描述和表达关系模型中的关系、属性等基本问题,定义和构造了一组核心关系代数运算谓词.着重讨论了Turbo-Prolog的外部数据库特性以及用于开发和维护大型关系数据库的优势和潜能,阐明了如何在Turbo-Prolog外部数据库中构造关系代数运算规则子句.The description and representation of relational model by means of Prolog clauses are discussed in this paper, and a group of the predicates of kerndl relational calculus are presented. The focus of discussion is on T-P external database and its potential advantages in the development and maintenance of large-scale relational database, also the way to build the rule clauses of relational calculus in T-P external database is demonstrated.
