How many tables?

A college library keeps everything in one table:

Loan(issue_id, book_isbn, book_title, author_name, author_country, member_id, member_name, member_dept, issue_date, due_date)

What is true about the data:

• issue_id is unique for every loan
• one ISBN is always one title, by one author
• one author has one country
• one member has one name and one department
• the same book can be borrowed many times, by different members

The librarian reports three problems. Corrections to an author's country have to be made in many rows. A newly acquired book that nobody has borrowed cannot be recorded at all. And when the last loan of a book is deleted, the book's details disappear from the database.
