Discovery Algorithms for Embedded Functional Dependencies
Summary: eFD discovery is NP-complete and W[2]-hard in the output, with a larger minimum solution space than classical FDs. Row-, column-, and hybrid data structures with efficient search enable scalable eFD discovery; ranking by redundant values highlights meaningful eFDs and showcases completeness benefits for approximate and genuine FDs.
