Question
In database management systems (DBMS), which
normalization form removes partial dependency?Solution
Second Normal Form (2NF) removes partial dependency, which occurs when a non-prime attribute is functionally dependent on part of a candidate key. A table is in 2NF if it is in 1NF and all non-key attributes are fully dependent on the primary key. Why Other Options are Wrong: a) 1NF deals with atomicity, ensuring that each column contains only indivisible values. c) 3NF removes transitive dependency, not partial dependency. d) BCNF is a stronger version of 3NF but does not specifically address partial dependency. e) 4NF deals with multi-valued dependencies.
