2.) I decided to create a new query and optimize itSelect Book_ID, BookTitle, Author_First_Name, Author_Last_NameFrom 1bookWhere Book_ID = ‘1234’Groupby BookID

3.) One recommendation that I would make to secure the database is to use user access management. This will help protect the database sensitive information because we would be able to define each user in the database. Also, we would be able to create passwords, and assign certain access rights to each account. For example an account may only have READ access to certain parts of the database. This would protect and allow us to not have to give full rights to an account that does not need them.
