Abstract
A computer implemented method for detecting errors in data includes obtaining one or more graph functional dependency (GFD) rules comprising a set of GFD rules, obtaining a set of GFDs representative of the data, building a canonical graph for the GFD rules, and determining that one or more GFD of the set of GFDs conflict based on the set of GFD rules and the canonical graph and, based thereon, determining an error in the set of GFDs.
