Scenario: A database administrator is designing a new database schema for an e-commerce platform. What normalization techniques would you recommend to ensure data integrity and minimize redundancy?

Normalization is crucial in database design to ensure data integrity and minimize redundancy. Third Normal Form (3NF) is widely used, as it reduces data redundancy by removing transitive dependencies. Boyce-Codd Normal Form (BCNF) is stricter than 3NF, eliminating all non-trivial functional dependencies and ensuring each determinant is a candidate key. Fourth Normal Form (4NF) deals with multi-valued dependencies, and Fifth Normal Form (5NF) addresses join dependencies, further enhancing data integrity and minimizing redundancy.
