Team project. A tool that uses Monte Carlo simulations to explore the practical viability of different database normalization forms based on functional dependencies. It reveals that while Third Normal Form (3NF) remains practical, achieving Boyce-Codd Normal Form (BCNF) becomes less feasible as the number of attributes in a database increases.
