Q1. Consider the following relational database for the GBP case.

Green Book Publisher (GBP) wants to maintain data about its authors, the books, editorial staff, and their work for the books. Each author has a unique author ID, name, address, telephone number, unique email address. A book has a unique ISBN, title, category, publication year, and publishing city. An author can write many books, and each book can be authored by many authors. An editorial staff member has a unique employee ID, employee name, title, and year hired. Some editorial staff members supervise others. Each book is usually edited by many editorial staff members. Each editorial staff member generally works for many books, but may not work for any book yet. Each time when an editorial staff member performs a specific editorial work for the book, the job type, start date, and end date are recorded. An editorial staff member can work for a book for multiple times with multiple start dates.

The database with five tables is described as follows.
