概率关系模式与概率XML模式转换算法的研究
Research on conversion algorithm between probabilistic relation schema and probabilistic XML schema
摘要
Abstract
This paper compared the representation method of probabilistic data based on possible world model in relation data model with of in XML data model. Distinguished probabilistic relation schema between the 1NF schema and the 3NF schema based on the relation of probability attribute and ordinary attribute. And also distinguished probabilistic XML schema between the 1NF schema and the 3NF schema based on the relation of probability node and ordinary node. Designed the conversion algorithms between probabilistic relation schema and probabilistic XML schema, i.e. extended DTD document. The instance analysis results show that the algorithms are effective. And it provided an effective schema conversion method between the existent probabilistic relation data transformation and probabilistic XML data.关键词
