摘要:
在处理不确定信息的概率关系模型PRM(Probabilistic Relational Model)的基础上,为了弱化关系中元组间互斥的约束条件,从事件发生条件概率和谓词的角度出发,进一步论述了概率关系数据库模式的语义、定义及相关操作,给出了更为合理的概率型数据库结构的形式化描述,并对关键字的定义、性质以及概率数据库更新、查询等应用方面做了深入研究.
Abstract:
Based on a probabilistic relational model PRM which can deal with indeterminate information, this article recomprehend its syntax purport, definition and operation concerned from the probability of the occurrence to debase the mutually exclusive restricted qualification between temples and putforward a logicaler formalized description of the structure of the probabilistic database and also do some deep research at the aspect of keywords’definition, character and the updating and querying application of the probabilistic database.
