How can database normalization help in properly categorizing customers and their orders in a PHP system?

Database normalization can help in properly categorizing customers and their orders in a PHP system by organizing the data into separate tables and reducing data redundancy. By breaking down the data into smaller, related tables, we can establish relationships between customers and their orders more efficiently. This ensures data integrity and makes it easier to manage and query the database. 

// Example of normalized tables for customers and orders

// Customers table
CREATE TABLE customers (
    id INT PRIMARY KEY,
    name VARCHAR(50),
    email VARCHAR(50)
);

// Orders table
CREATE TABLE orders (
    id INT PRIMARY KEY,
    customer_id INT,
    order_date DATE,
    total_amount DECIMAL(10, 2),
    FOREIGN KEY (customer_id) REFERENCES customers(id)
);
