functional dependency technical

Each left side of a functional dependency in is unique.

Functional dependency was based on need for assistance with activities of daily living.

A classic example of functional dependency is the employee, department model.

Reducing any functional dependency will change the content of S.

This basic fact can be expressed by a functional dependency:

Functional dependencies are another type system feature that have similar uses to associated types.

These three rules are a sound and complete axiomatization of functional dependencies.

Database theory has a concept called functional dependency, written .

Each right set of a functional dependency of S contains only one attribute.

Every set of functional dependencies has a canonical cover.

Let be a set of functional dependencies on .

It is in fact the base-point from which jets derive their functional dependency.

Certain sets of functional dependencies lead to exponentially many candidate keys.

Functional dependency The degree to which an attribute is an inherent characteristic of an entity type.

This case represents an example where multiple functional dependencies are embedded in a single representation of data.

A functional dependency is a special case of multivalued dependency.

Type families are regarded as being generally easier to type-check than functional dependencies.

This example illustrates the concept of functional dependency.

In this constraint, there is a functional dependency .

The most common uses of functional dependencies can be directly converted to associated types and vice versa.

A key concept is functional dependency, which is often referred to as determinacy.

A functional dependency on part of any candidate key is a violation of 2NF.

Thus the functional dependency still holds true.

Functional dependency is frequently illustrated by an arrow.

Functional dependencies, which constrain parts of that relation to be a mathematical function on types.
