Efficient discovery of functional dependencies and armstrong relations
In this paper, we propose a new efficient algorithm called Dep-Miner for discovering minimal
non-trivial functional dependencies from large databases. Based on theoretical foundations …

Achievements of relational database schema design theory revisited
J Biskup - International Workshop on Semantics in Databases, 1995 - Springer
Database schema design is seen as to decide on formats for time-varying instances, on
rules for supporting inferences and on semantic constraints. Schema design aims at both …
