Abstract
This CCFD paper explores the idea of discovering the constant conditional functional dependencies (CCFDs). Constant CFDs are particularly important for object identification, which is essential to data cleaning and data integration. The further algorithm provides a set of cleaning rule discovery tools for users to choose it for different applications. These CCFDs are derived from conditional functional dependencies (CFDs). The algorithm is implemented for finding the constant conditional functional dependencies from a given relation.
