摘要： 随着信息与通讯技术的快速发展，数据管理正面临着越来越多的挑战，其中之一就是数据的不确定性。提出一种基于元组存在性的概率数据模型 关键词: 数据不确定，概率数据库，概率数据模型，概率关系代数 Abstract: With the development of ICT, data management has meet more and more challenge, one of challenge is uncer tainty of data. This paper proposed a probabilistic data model based on existence of tuple, compared with other models,this model was proved to be complete, and we proposed corresponding probabilistic relational algebra and query algo rithm. Key words: Uncertain data, Probabilistic database, Probabilistic data model, Probabilistic relational algebra 引用本文 陈鹏. 基于元组存在性的概率数据模型研究[J]. 计算机科学, 2012, 39(Z6): 265-270. https://doi.org/ 使用本文 0 / / 推荐 导出引用管理器 EndNote|Reference Manager|ProCite|BibTeX|RefWorks 链接本文: https://www.jsjkx.com/CN/ https://www.jsjkx.com/CN/Y2012/V39/IZ6/265
