The only reason for the existence of relations is to store instances of functional dependencies.
A. True
B. False
Answer: Option A
Solution (By Examveda Team)
Option1: TrueRelations in the relational model are used to store data in a structured way. Functional dependencies are a key concept in database normalization, which helps in organizing data efficiently. Therefore, the main purpose of relations is indeed to store instances of functional dependencies.
Option2: False
Relations in the relational model serve a broader purpose than just storing instances of functional dependencies. They are used to represent entities, attributes, and relationships in a database, allowing for data manipulation and retrieval. While functional dependencies play a crucial role in database design, they are not the sole reason for the existence of relations.
Therefore, the correct option is Option1: True.
