CREATE TABLE Customers (
    customer_id SERIAL PRIMARY KEY,
    name VARCHAR(255),
    gender CHAR(1),
    rewards_member BOOLEAN
);

CREATE TABLE Orders (
    order_id SERIAL PRIMARY KEY,
    sales_date DATE,
    customer_id INT REFERENCES Customers(customer_id)
);

CREATE TABLE Items (
    item_id SERIAL PRIMARY KEY,
    name VARCHAR(255),
    price DECIMAL(10, 2)
);

CREATE TABLE Order_Items (
    order_id INT REFERENCES Orders(order_id),
    item_id INT REFERENCES Items(item_id),
);
