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."
