A functional dependency is always an equation.

Solution (By Examveda Team)

Option1: True
- In the context of the relational model and normalization, a functional dependency is a relationship between two attributes in a relation. It is represented as X -> Y, where X determines Y uniquely. This relationship is not necessarily an equation but rather a logical statement about the data.

Option2: False
- A functional dependency is not always an equation. It is a statement about the relationship between attributes in a relation, indicating that the value of one attribute uniquely determines the value of another. It is a fundamental concept in database normalization.

Conclusion:
- The correct option is False. A functional dependency is not always an equation but a logical relationship between attributes in a relation.
