• Query the pre-orderable products: Query the products with sufficient inventory from the product table and the current time is between the reservation start and end dates.
• Submit an order: When the user selects the product to be reserved, click the "Reserve" button to insert the product information and the user's information into the order table, and reduce the inventory by the corresponding amount.
• Confirm order: After the merchant reviews the order, it updates the order status to "Confirmed" and sends a confirmation message to the user.
• Modify reservation: If the user needs to modify the reservation information, he can refill the form and update the original order information to the new order information.
• Cancel reservation: If the user needs to cancel the reservation, he can select the corresponding order, update the order to "cancelled" in the order status, and increase the inventory accordingly.

In order to provide a better user experience, it is necessary to design a simple and intuitive front-end page, including the following content:

• Product list: Displays the currently available product list.
• Order page: When the user clicks the "Reservation" button, it jumps to the order page, which displays the order information of the currently reserved product.
• Reservation rules: Display the reservation rule information set by the merchant on the order page.
• Order management: Merchants can view, review, cancel reservations and other operations in the backend management interface.
