When there is a composite key and only one part of the primary key is needed to determine one or more other attributes of a table, what is called?
Correct answer: C. Determinant
- A. Partial dependency
- B. Transitive dependency
- C. Determinant
- D. Manually Exclusive
Explanation
Determinant is the term used in relational databases to describe a single attribute (part of a composite key) that can be used to uniquely identify all the other attributes in a row (tuple) of a table. In simpler terms, it's the single attribute within a composite key that holds the power to determine all other attributes' values for that specific row In conclusion, a determinant is the single attribute within a composite key that acts as the sole identifier for all other attributes in a particular row of a database table

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.
