An online book selling shop, BOI-POKA.com has recently launched its website. When a customer makes an inquiry about a book, the system first checks the availability of the book. If the book is available then the customer needs to validate him/herself. If a book is unavailable, the system shows an error message to the customer and also saves the list of unavailable books in a file. If a customer fails to validate him/herself, can register into the system and issue a book. For valid customers, the number of books issued to him is checked. If the maximum quota exceeds then an error message is shown to the customer. Otherwise the book is issued to the customer. After issuing the book the system updates the database and prints a receipt. In this way customers can receive the book. Please Draw a Activity diagram based on the above scenario.
