In relational database theory, a functional dependency is the following constraint between two attribute sets in a relation: Given a relation R and attribute...

Functional dependency Functional dependency is the property that a value in a tuple may be derived from another value in that tuple. A functional dependency...

attributes (e.g. database columns) are functionally dependent on solely a key, except the case of functional dependency whose right hand side is a prime attribute...

By using BCNF, a database will remove all redundancies based on functional dependencies. Edgar F. Codd released his original article "A Relational Model...

multivalued dependency is a full constraint between two sets of attributes in a relation. In contrast to the functional dependency, the multivalued dependency requires...

its dependency on Format can be preserved: Now, both the Book and Price tables conform to 2NF. The Book table still has a transitive functional dependency...

for F (a set of functional dependencies on a relation scheme) is a set of dependencies such that F logically implies all dependencies in F c {\displaystyle...

Dependency injection involves four roles: services, clients, interfaces and injectors. A service is any class which contains useful functionality. In...

However, logical implication between dependencies that can be inclusion dependencies or functional dependencies is undecidable by reduction from the word...

join dependency is to say that the relationships in the join dependency are independent of each other. Unlike in the case of functional dependencies, there...
