摘要 基于复杂对象的逻辑推理一直是演绎对象数据库中的研究热点。论文叙述了集合在演绎对象数据库中的应用和实现技术,重点介绍了部分集在规则中的两个作用:列举集合中的所有元素和聚集集合中所有元素。同时讨论了完整集的交、并、划分和差等运算的实现思想。 Logic reasoning based on complex objects has always been a research focus in deductive object-oriented database.Application and implementation techniques of sets in deductive object-oriented database are described in this paper.It focuses on two functions of partial sets:enumerating all elements of sets and grouping all elements of sets. Meanwhile it discusses implementation ideas of intersection,union,division and difference operations of sets.
