Are there any potential pitfalls or limitations to consider when creating multiple tables in a MySQL database for user data storage?

One potential pitfall to consider when creating multiple tables in a MySQL database for user data storage is the complexity of managing relationships between the tables. To address this, it is important to properly define and enforce foreign key constraints to maintain data integrity and ensure that related data remains consistent across tables. 

CREATE TABLE users (
    id INT PRIMARY KEY,
    username VARCHAR(50) NOT NULL,
    email VARCHAR(100) NOT NULL
);

CREATE TABLE user_details (
    user_id INT,
    full_name VARCHAR(100) NOT NULL,
    address VARCHAR(255),
    FOREIGN KEY (user_id) REFERENCES users(id)
);
