How to transform 2NF to 3NF?

To transform a database schema from Second Normal Form (2NF) to Third Normal Form (3NF), you need to eliminate transitive dependencies. This involves identifying attributes that depend on non-key attributes and moving them to separate tables. Each non-key attribute should only depend on the primary key of its table. After restructuring, ensure that all tables are in 2NF before proceeding to achieve 3NF.
