@sakshi300699 @rupeshmohanty now I think it is clear and I hope it my PR accepted :)

@Raghad-Khaled I don't see any difference in the output except the database configuration. How is the new configuration better than the previous one?

[Raghad-Khaled]

@rupeshmohanty The previous configuration on Relation Project is not in 1NF (First-Normal-Form) because of multi-valued attribute tags and in the article in the link show my opinion https://www.geeksforgeeks.org/first-normal-form-1nf/ as the database schema should be normalized.
