2NF eliminates partial dependencies, while 3NF eliminates transitive dependencies.
2NF eliminates partial dependencies by ensuring all non-key attributes are fully functionally dependent on the primary key.
3NF eliminates transitive dependencies by ensuring that non-key attributes are not dependent on other non-key attributes.
Example: In a table with columns A, B, and C where A is the primary key, if B depends on A and C...
