What about defining primary keys? Why is that necessary?
Defining primary keys ensures that each record is unique, which helps maintain data integrity and prevents redundancy.
Are there any tools that can help with normalization?
Yes, tools like SQL, Python libraries (like Pandas), and ETL software can assist in the normalization process.
