What are the benefits of SQL normalization?
SQL normalization helps reduce data redundancy and improve data integrity by organizing data into related tables.
Can you explain how it improves data integrity?
By ensuring that each piece of data is stored only once, normalization minimizes the risk of inconsistent data across the database.
Are there any performance drawbacks to normalization?
Yes, while normalization can improve data integrity, it may lead to more complex queries and potentially slower performance due to multiple table joins.
What are the different normal forms in SQL?
The main normal forms are 1NF (First Normal Form), 2NF (Second Normal Form), 3NF (Third Normal Form), and BCNF (Boyce-Codd Normal Form).
