Appropriate inferences of data dependencies in relational databases
J Biskup, S Link - Annals of mathematics and artificial intelligence, 2011 - Springer
We study inference systems for the combined class of functional and full hierarchical
dependencies in relational databases. Two notions of implication are considered: the …
