Normalization

What is database normalization?

• The process of organizing data into tables and columns

• The process of removing duplicate data from a database

• The process of structuring a database to minimize redundancy and dependency

• The process of indexing data for faster retrieval

Which of the following is not a normal form in database normalization?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Primary Normal Form (PNF)

• Third Normal Form (3NF)

In database normalization, which normal form ensures that each column in a table is dependent on the primary key?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Third Normal Form (3NF)

• Fourth Normal Form (4NF)
  

Which normal form eliminates transitive dependencies?

• First Normal Form (1NF)

• Third Normal Form (3NF)

• Second Normal Form (2NF)

• Boyce-Codd Normal Form (BCNF)

What is the purpose of denormalization in database design?

• To increase data redundancy

• To improve data integrity

• To simplify database queries and improve performance

• To reduce storage requirements

Which normal form allows for multivalued dependencies to be eliminated?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Third Normal Form (3NF)

• Fourth Normal Form (4NF)

Which normal form guarantees that there are no non-prime attributes functionally dependent on a proper subset of any candidate key?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Third Normal Form (3NF)

• Boyce-Codd Normal Form (BCNF)

What is a functional dependency in the context of database normalization?

• The relationship between two or more tables in a database

• The relationship between primary and foreign keys in a table

• The relationship between data types in a database schema

• The relationship between attributes in a table, where the value of one attribute determines the value of another

Which normal form allows for a dependency on a candidate key, as well as on other non-key attributes?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Third Normal Form (3NF)

• Boyce-Codd Normal Form (BCNF)

Which normal form is considered the highest level of normalization?

• First Normal Form (1NF)

• Second Normal Form (2NF)

• Boyce-Codd Normal Form (BCNF)

• Third Normal Form (3NF)
