develop a bookstore information system. The bookstore
manages a collection of books it is selling, book orders, and customers who purchased from the store. A
book store also has a counter that accepts cash from book sales. Each book Customer can search for a
book by its ID, title, author, publisher, edition, year of publication and price. The book store also records
the number of copies available for each book. Customers can order a book from the bookstore. The
bookstore needs to keep information about its customers such as customer id, first name, last name,
phone, city and country. For every book purchase, the bookstore creates an order that stores the
customer id, book isbn, the quantity and the purchase date. The order sales will be added to the counter
cash that accepts money on each book sale. Your system can provide reports about all the books in the
store, book orders made, and customers who purchased books from this store.
