The attribute on the left-hand side of the arrow in a functional dependency is the
Correct answer: A. Candidate Key
- A. Candidate Key
- B. Determinant
- C. Foreign Key
- D. Primary Key
Explanation
In a functional dependency (FD), denoted by an arrow (->), the attribute(s) on the left side of the arrow determine the attribute(s) on the right side. The left side is often referred to as the determinant or independent side. A candidate key is a minimal set of attributes that uniquely identifies rows in a table. While a table can have multiple candidate keys, there can only be one primary key. So, the determinant in a functional dependency can be a candidate key, but not necessarily the primary key.

About Databases
Databases cover tables, records, fields, keys and relationships, together with database management systems and relational database design. The subject includes primary and foreign keys, normalization, SQL commands such as SELECT, INSERT, UPDATE and DELETE, queries, forms and reports, while distinguishing a database from a spreadsheet used for simple tabular data.
