The database design of the online bookstore should include the following components:
1. Item Information Table (Item) -Store the basic information of the item such as title, author, price, description, classification, etc.
2. Order Information Table ( Order) -Store the order information of the customer, including the order number, customer name, order status, order items, etc.
3. Stock-Storage of stock information, including item number, stock quantity, purchase date, supplier, etc.
4. Order Management-used to record all orders created, modified, deleted, and the status of the order (completed, in progress, not processed, etc.).
5. Customer Information Form-used to record the basic information of the customer, such as name, email address, telephone number, etc.
6. The payment information table-used to record all payment methods such as credit card, AliPay, Weixin Pay, etc.
7. The supplier information sheet-used to record the basic information of the supplier, such as company name, address, contact information, etc.
The following is a simple online bookstore database design example. The product information table, order information table, and inventory information table already include some basic data fields:
```
--Item Information Form (Product)
CREATE TABLE Product (
Product_ID INT PRIMARY KEY
Product_Name VARCHAR(50) NOT NULL
Product_Price DECIMAL(10 2) NOT NULL
Product_Description TEXT NOT NULL
Product_category VARCHAR(20) NOT NULL
FOREIGN KEY (Product_ID) REFERENCES Product(ID)
);
--Order Information Form (Order)
CREATE TABLE Order (
Order_ID INT PRIMARY KEY
Customer_Name VARCHAR(50) NOT NULL
Order_Status VARCHAR(20) NOT NULL
Order_Product VARCHAR(50) NOT NULL
Order_Time TIMESTAMP NOT NULL
FOREIGN KEY (Order_ID) REFERENCES Order(ID)
);
--Storage Information Form (Stock)
CREATE TABLE Stock (
Stock_ID INT PRIMARY KEY
_
Arrival_Date Date NOT Empty
<strong></strong><strong></strong>
FOREIGN KEY (Stock_ID) REFERENCES Stock(ID)
);
--Order Management
CREATE TABLE Order Management (
Order_ID INT NOT NULL
Order_'s status VarCHAR(20) NOT nil
Order_'s method VARCHAR(20) NOT nil
FOREIGN KEY (Order_ID) REFERENCES Order(ID)
);
--Customer Information Form
CREATE TABLE Customer (
Customer_ID INT NOT NULL
Customer_Name VARCHAR(50) NOT NULL
Customer_Email VARCHAR(100) NOT NULL
Customer_Phone VARCHAR(20) NOT NULL
FOREIGN KEY (Customer_ID) REFERENCES Customer(ID)
);
--payment information form (Payment)
CREATE TABLE Payment (
Payment_ID INT NOT NULL
Payment_Name VARCHAR(50) NOT NULL
Payment_Type VARCHAR(20) NOT NULL
Payment_Time TIMESTAMP NOT NULL
FOREIGN KEY (Payment_ID) REFERENCES Payment(ID)
);
```
In the above design, each table has a unique ID as the primary key to ensure the uniqueness and integrity of the data. At the same time, in order to support multi-currency transactions, the payment information table also included a payment type field to distinguish different payment methods.

The online name " Beacon Fire Playing with the Dukes " meant " Igniting the Beacon Fire Playing with the Dukes ". It described a person who exaggerated, made something out of nothing, or deliberately exaggerated his role in order to achieve a certain purpose at banquets or other occasions for entertainment or decoration.
When designing a web name, you can understand it as an idiom and combine it with other elements to name it. For example,"Beacon" could be understood as "Beacon Tower" and "Playing with the Dukes" could be understood as "Playing with the Dukes". This way, a net name such as "The Dukes of Beacon Tower" could be designed.
In addition, you can also combine other elements to design an online name such as "Beacon Fire in the Sky". By understanding "Beacon Fire" as "Beacon Tower" and "Beacon Fire in the Sky" as "Continuous", you can design an imaginative online name such as "The Lord of Beacon Fire in the Sky".
The online name of "Beacon of Fire" could combine the two elements of "Beacon of Fire" and "Beacon of Fire" with other elements to create an imaginative and cultural name.
Maintain a consistent color scheme. This gives your stories a more professional and cohesive look. For example, if you're a beauty brand, you might use pastel colors throughout your stories. Also, use fonts that are easy to read. Avoid overly fancy or hard - to - read fonts.
Use text effectively. Choose fonts that are easy to read and make sure the text size is appropriate for mobile viewing. Highlight important words or phrases. For example, if you're promoting a sale, make the percentage off or the discount code stand out.
