A key:

A relation is in Boyce-Codd Normal Form (BCNF) if every determinant is a composite key.

Row is synonymous with the term:

A functional dependency is a relationship between or among attributes.

The only reason for the existence of relations is to store instances of functional dependencies.

In a relation, the rows are sometimes called "records."

An attribute is a(n):

A functional dependency is always an equation.

The primary key is selected from the:

A key is a group of one or more attributes that uniquely identifies a row.

A relation is in 5NF when multivalued dependencies are isolated in their own relation.

A relation is a two-dimensional table.

Any table that meets the definition of a relation is said to be in first normal form.

A relation has cells that hold multi-value entries.

Keys made up of two or more attributes are called composite keys.

Given the functional dependency R → S , R is called the determinant.

The functional dependency R → S means that the value of S can be determined when we are given a value of R.

In a relation, the columns are sometimes called "attributes."

Given the functional dependency R → (S,T) , then it is also true that R → S.

In a relation, the rows are sometimes called "fields."
