摘　　要：文章从介绍概率数据库的概念入手,分析了在实际应用中为了更灵活地操作关系中的元组,在原来的概率数据库基础上增加对元组之间存在的关系操作的必要性。文章提出在概率数据库中表示元组间存在的各种关系的方法,并且对这种改进进行了可行性分析。Starting with the introduction of the concept of probability database, this paper analyzes the necessity to increase operations of relationships existing in the tuples based on the original database for being more flexible to operating the tuples in relationship in practical application. The methods for representing all kinds relationships existing in tuples in probability database have been put forward and feasibility analysis about the improvement was done in this paper.
