Repeatability - DCs

This is a repeatability page for DC discovery algorithms. The algorithms are provided in the state their results have been published, but they may not represent the most recent version of their implementations.

DC Algorithms

The efficient discovery of denial constraints in tables is a challenging task. We have released a hybrid DC discovery algorithm "Hydra", which is available as part of the metanome-algorithms respository. The data profiling tool Metanome provides standardized interfaces to facilitate the comparison of different DC discovery methods.


All DC algorithms have been exhaustively tested on the following datasets:
