The Theory of Functional and Subset Dependencies Over Relational Expressions
A formal system for reasoning about functional dependencies (FDs) and subset dependencies (SDS) defined over relational expressions is described. An FD e: X +Y indicates that Y is functionally dependent on X in the relation denoted by expression e; an SD e c f indicates that the relation denoted by e is a subset of that denoted by f. The system is shown to be sound and complete by resorting to ...
متن کاملLearning Statistical Patterns in Relational Data Using Probabilistic Relational Models
Many real-world domains are relational in nature, consisting of a set of objects related to each other in complex ways. This paper focuses on predicting the existence and the type of links between entities in such domains. We apply the relational Markov network framework of Taskar et al. to define a joint probabilistic model over the entire link graph — entity attributes and links. The applicat...
متن کاملFunctional Dependencies in a Relational Data Base and Propositional Logic
An equivalence is shown between functional dependency statements of a relational database, where “+” has the meaning of “determines,” and implicational statements of propositional logic, where “.$” has the meaning of “implies.” Specifically, it is shown that a dependency statement is a consequence of a set of dependency statements iff the corresponding implicational statement is a consequence o...
متن کاملFunctional Dependencies Analyse in Fuzzy Relational Database Models
This paper presents a literature overview of Fuzzy Relational Database Models with emphasis on the role of functional dependencies in logical designing and modeling. The aim is the analysis of recent results in this fi eld. Fuzzy set theory is widely applied for the classical relational database extensions resulting in numerous contributions. This is because fuzzy sets and fuzzy logic are power...
