Empirical evidence for the usefulness of Armstrong relations in the acquisition of meaningful functional dependencies
WD Langeveldt, S Link - Information Systems, 2010 - Elsevier
Armstrong relations satisfy precisely those data dependencies that are implied by a given
set of data dependencies. A common perception is that Armstrong relations are useful in the …

Semantic sampling of existing databases through informative Armstrong databases
F De Marchi, JM Petit - Information Systems, 2007 - Elsevier
Functional dependencies (FDs) and inclusion dependencies (INDs) convey most of data
semantics in relational databases and are very useful in practice since they generalize keys …
