The problem is below

The faculty and students (we refer to them in our system as clients) can electronically check out any book at any time. A book must have at least one author but can have more authors. An author must have written at least one book or more to be included in the system. A book may have never been checked out, but can be checked out many times by the same client or different clients over time. A client may have never checked out a book or they may have checked out many books over time. To simplify determining which client currently has a given book checked out, a M:N relationship between BOOK and CLIENT should be maintained. The information recorded for each book is book number, book title, book subject, and year of publication. For each author, the library records the author ID, first and last name and year of birth. Because all faculty and students in the department are given accounts at the online library, the client ID, first and last name and client type need to be stored. Finally, checkout out date, checkout due date and checkout in date for each book must be tracked.
