In 2NF, which form of dependency is removed
Correct answer: B. Partial
- A. Functional
- B. Partial
- C. Associative
- D. Transitive
Explanation
In a relational database, a partial dependency exists when a non-prime attribute (an attribute that is not part of the primary key) is dependent on only a part of the candidate key (a minimal set of attributes that uniquely identifies a row in a table). This can lead to data redundancy and inconsistencies. Second Normal Form (2NF) specifically addresses this issue by eliminating partial dependencies

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.
