发明名称 METHOD AND SYSTEM FOR ACCELERATED DATA QUALITY ENHANCEMENT
摘要 Embodiments of the present invention solve the technical problem of identifying, collecting, and managing rules that improve poor quality data on enterprise initiatives ranging from data governance to business intelligence. In a specific embodiment of the present invention, a method is provided for producing data quality rules for a data set. A set of candidate conditional functional dependencies are generated comprised of candidate seeds of attributes that are within a certain degree of relatedness in the ontology of the data set. The candidate conditional functional dependencies are then applied to the data refined until they reach a quiescent state where they have not been refined even though the data they have been applied to has been stable. The resulting refined candidate conditional functional dependencies are the data enhancement rules for the data set and other related data sets. In another specific embodiment of the present invention, a computer system for the development of data quality rules is provided having a rule repository, a data quality rules discovery engine, and a user interface.
