What are the potential pitfalls of implementing a new column like "reihenfolge" in the user table for managing menu item order in PHP?

One potential pitfall of implementing a new column like "reihenfolge" in the user table for managing menu item order in PHP is the risk of data inconsistency if the ordering values are not properly updated or maintained. To solve this issue, consider using a separate table specifically for managing menu item order, linking it to the user table with a foreign key constraint. This way, the ordering information is kept separate from user data, reducing the risk of data corruption.

// Create a new table for managing menu item order
CREATE TABLE menu_order (
    id INT PRIMARY KEY,
    user_id INT,
    item_id INT,
    order_value INT,
    FOREIGN KEY (user_id) REFERENCES users(id),
    FOREIGN KEY (item_id) REFERENCES menu_items(id)
);

// Update the user table to remove the "reihenfolge" column
ALTER TABLE users DROP COLUMN reihenfolge;
