Systems and methods for data quality management

摘要

Systems and methods that model and measure the propagation of error within information systems. The invention provides data management systems that determine an error measure that represent the accuracy, or inaccuracy of a query result achieved for processing a structured data set. In one embodiment, the invention provides systems that have a model of error which exists within a structured data set. The system can further include an error propagation monitor that processes the error model and the structured data set to determine errors within the structured data set that will propagate to a query result generated by performing a query process on the structured data set. The propagated error represents the error that exists within the query result signal.
