Q.1.
A functional dependency is a relationship between or among:
Q.2.
A primary key is a composite key that was selected to be the main identifier for the relation.
Q.3.
A primary key is a composite key that was selected to be the main identifier for the relation.
Q.4.
A primary key is a composite key that was selected to be the main identifier for the relation.
Q.5.
A primary key is a composite key that was selected to be the main identifier for the relation.
Q.6.
Relations are categorized into normal forms according to the referential integrity constraints that they have.
Q.7.
A relation is in Boyce-Codd Normal Form (BCNF) if every determinant is a composite key.
Q.8.
A functional dependency is always an equation.
Q.9.
A relation has cells that hold multi-value entries.
Q.10.
In a relation, the rows are sometimes called "fields".
Q.11.
A candidate key is a determinant that determines all the other columns is a relation.
Q.12.
The only reason for the existence of relations is to store instances of functional dependencies.
Q.13.
A relation is in 5NF when multivalued dependencies are isolated in their own relation.
Q.14.
In a relation, the order of the columns does not matter.
Q.15.
A functional dependency is a relationship between or among attributes.
Q.16.
A key is a group of one or more attributes that uniquely identifies a row.
Q.17.
The functional dependency R → S means that the value of S can be determined when we are given a value of R.
Q.18.
In a relation, the columns are sometimes called "attributes".
Q.19.
Keys made up of two or more attributes are called composite keys.
Q.20.
Given the functional dependency R → S , R is called the determinant.
