Storing and Querying Data Using a Probabilistic Relational DBMS
A data integration system needs to deal with the three levels of uncertainty, the uncertainty of the data source, schema mapping uncertainty, uncertainty query. In this paper, a algorithm intends to use technology based on semantics, schema mapping for data integration solution space of possible worlds model to study the objects semantic knowledge of the possibility of the solution space of the solution set, through this research project to build the solution based on semantic model Spatial choice model to address uncertainty in a probability model for data fusion schema mapping problems in the complexity and increase the uncertainty of data quality and data integration, data query based on the reliability of uncertainty.
