What is the difference between functional dependency and multi-valued dependency?
- Functional dependency and multi-valued dependency are terms used interchangeably to describe the same concept.
- Functional dependency captures the relationship between attributes within a single table, ensuring unique determinants for other attributes. Multi-valued dependency, on the other hand, deals with situations where one attribute uniquely determines another, but multiple values can exist for the same determinant.
- Functional dependency only applies to numeric attributes, while multi-valued dependency is exclusive to alphanumeric attributes.
- Functional dependency signifies a one-to-one relationship, while multi-valued dependency implies a many-to-many relationship.
Functional dependency and multi-valued dependency are distinct concepts. Functional dependency deals with one-to-one relationships within a table, whereas multi-valued dependency handles situations where one attribute uniquely determines another, allowing for multiple values for the same determinant.
