(please design sequence diagram for this scenario)
When the researcher accesses the website to borrow a specific book. The system will request the researcher's data. If the user is new, the system will ask to record the data. If the user has already subscribed to the site, it records the users name with the secret code only. After the researcher enters his password, the system verifies that the entered password is correct. If the password is incorrect, the system displays a message inviting the customer to re-enter his password, but if the customer entered the password incorrectly three times, the user is terminated from entering. If the password is correct, the system enters the searcher into the website The system allows the searcher to browse and search for the name and location of the book on the site. The system shows the complete name of the book and its type along with the author's name and the date of publication that the researcher searched for. If the book is on the site, the researcher is allowed to borrow it, and if it is not available, then he returns to the home page. When the researcher borrows the book, the system records the date of borrowing and the date of return with the name of the book. If the researcher delays returning the book, the system alerts the researcher with notifications or text messages to return the pseudonym. If the researcher wants to exit the site, he will press Logout. The system updates the location data.
