Database Normalisation Questions
The role of foreign key constraints in database normalization is to establish and enforce referential integrity between tables. Foreign key constraints ensure that the values in a column (foreign key) of one table correspond to the values in a primary key column of another table. This helps maintain data consistency and prevents inconsistencies or anomalies in the database. By using foreign key constraints, database normalization ensures that relationships between tables are properly defined and maintained, leading to a more efficient and reliable database structure.
