Relations are categorized into normal forms according to the referential integrity constraints that they have.
A. True
B. False
Answer: Option A
Solution (By Examveda Team)
Option1: TrueRelations are indeed categorized into normal forms based on the referential integrity constraints they adhere to. Normalization is the process of organizing data in a database to minimize redundancy and dependency by dividing large tables into smaller tables and defining relationships between them. The different normal forms, such as 1NF, 2NF, 3NF, and BCNF, are based on specific rules regarding referential integrity constraints.
Option2: False
This statement is incorrect. Relations are actually categorized into normal forms based on the referential integrity constraints they follow. The level of normalization a relation has achieved is determined by how well it adheres to these constraints.
Conclusion: The correct option is Option1: True. Relations are categorized into normal forms according to the referential integrity constraints they have.
