Microsoft SQL Server Database Quiz Questions

A table is in 3NF if it is in 2NF and has no transitive dependencies, meaning all non-key attributes must depend only on the primary key.

Partial dependencies are eliminated in Second Normal Form (2NF). 3NF focuses on eliminating transitive dependencies.

In 3NF, all non-key attributes must be directly dependent on the primary key, not on other non-key attributes.

3NF builds upon 2NF. Therefore, a table must first be in 2NF before it can be converted to 3NF.

While 3NF eliminates transitive dependencies, partial dependencies are addressed in 2NF.

3NF specifically eliminates transitive dependencies. A table with transitive dependencies cannot be considered in 3NF.

Derived attributes are not directly related to 3NF. 3NF focuses on eliminating transitive dependencies among non-key attributes.

While 3NF eliminates transitive dependencies, some redundancy might still exist if higher normal forms are not applied.

3NF requires that all non-key attributes depend solely on the primary key, and not on other non-key attributes.

3NF addresses transitive dependencies but does not completely resolve all data redundancy issues. Higher normal forms may be needed.

Repeating groups are eliminated in First Normal Form (1NF). 3NF specifically focuses on transitive dependencies.

Partial dependencies are handled in Second Normal Form (2NF). 3NF eliminates transitive dependencies rather than addressing partial dependencies.

3NF requires that non-key attributes depend only on the primary key and not on other non-key attributes.

3NF does not require a table to have a composite primary key. The focus is on eliminating transitive dependencies, regardless of the type of primary key.

While BCNF is a stricter version of 3NF, achieving 3NF does not require a table to be in BCNF. BCNF addresses additional anomalies not covered by 3NF.

A table is in 3NF if it is in 2NF and all non-key attributes are non-transitively dependent on the primary key.

3NF ensures that a table has no transitive dependencies. Other characteristics are related to different normal forms.

Removing transitive dependencies is essential for achieving 3NF.

A table must first be in Second Normal Form (2NF) before it can be converted to 3NF.

3NF addresses transitive dependencies. Other normalization forms address partial dependencies, repeating groups, and derived attributes.

3NF eliminates transitive dependencies to ensure that all non-key attributes depend only on the primary key.

The primary goal of 3NF is to eliminate transitive dependencies from a table.

A table in 3NF must have all non-key attributes directly dependent on the primary key, and no transitive dependencies.

Transitive dependencies are eliminated in Third Normal Form (3NF).

3NF extends from Second Normal Form (2NF) by eliminating transitive dependencies.

3NF focuses on removing transitive dependencies. Partial dependencies are addressed in 2NF, while repeating groups are handled in 1NF.

A table must first be in Second Normal Form (2NF) before it can be converted to 3NF.

To ensure a table is in 3NF, focus on removing transitive dependencies. Partial dependencies are addressed in 2NF.

Transitive dependencies are specifically addressed in Third Normal Form (3NF).

To meet 3NF requirements, ensure that all non-key attributes are dependent only on the primary key and there are no transitive dependencies.

3NF eliminates transitive dependencies. Other normal forms address partial dependencies and repeating groups.

To achieve 3NF, a table must first satisfy the requirements of Second Normal Form (2NF).

For a table to be in 3NF, it must have no transitive dependencies, and all non-key attributes must depend directly on the primary key.

3NF eliminates transitive dependencies where non-key attributes depend on other non-key attributes.

This is a characteristic of Third Normal Form (3NF), which eliminates transitive dependencies.

Third Normal Form (3NF) specifically targets the removal of transitive dependencies from a table.

In 3NF, all non-key attributes should be dependent only on the primary key, with no transitive dependencies.

3NF aims to eliminate transitive dependencies. Goals like removing repeating groups or derived attributes are handled by other normalization forms.

3NF is achieved by ensuring there are no transitive dependencies and all non-key attributes depend only on the primary key.

A table must first be in Second Normal Form (2NF) before it can be converted to 3NF.

Transitive dependencies are specifically addressed in Third Normal Form (3NF).

3NF requires that non-key attributes be dependent only on the primary key and not on other non-key attributes.

The main focus of 3NF is to eliminate transitive dependencies to ensure that all non-key attributes depend only on the primary key.

3NF requires no transitive dependencies and that all non-key attributes depend directly on the primary key, not other attributes.

This requirement is met by Third Normal Form (3NF), which eliminates transitive dependencies.
